Hello! I am a respiratory care practitioner who is also a diver. So you are right! Carbon dioxide acts as a trigger to ventilate because we possess chemoreceptors in different areas of our body that react to oxygen, carbon dioxide and hydrogen (hydrogen ions being the main source of ventilatory response. Carbon dioxide possesses a value of hydrogen ions so you can argue that the reaction to carbon dioxide is secondary). Oxygen, in one reaction, actually works as a mechanism to dull chemoreceptor response to hydrogen ions, therefore, switching to a lower percent oxygen or higher percent oxygen at a given level of hypercapnia will have an inverse relationship with your respiratory rate (lower [oxygen]=higher resp. rate, higher [oxygen] lower resp. rate) but this mechanism I have not seen in action in healthy individuals, but is pronounced with people who have chronic lung disease. Sorry to be writing an essay, but to answer your question on building CO2 while working to eliminate CO2 can be answered in terms of the degree of increased work of breathing vs ventilatory support. So if your work of breathing is greater than the amount of support you have then you will go into respiratory failure (Our natural support is our muscles of inspiration i.e. the diaphragm, internal intercostals). If your support is equal to or outperforms your work of breathing your urge to ventilate and work of breathing will tend to diminish after 5-10 minutes as the doctor was saying (assuming you have no chronic lung disease or anything like that). So since the only airway support you have underwater is your regulator and muscles to inhale, if you have a CO2 hit AND you also have venturi/rotator knob adjustment then that may help relieve some of the work you have to produce with your muscles alone, although I haven't heard anything to support this. But after analyzing many blood samples from patients with acute non-chronic hypercapnia, I can get a high level of CO2 (PaCO2) initially and after I put them on a BIPAP or invasive ventilator I will usually see a reduction to normal levels within 10 minutes. I hope this helped and I didn't butcher any explanations. Oh and also. Woody and Gus, love your videos, they definitely have made me a more conscious diver. Don't change a thing. You guys rock and looking forward to the next dive talk trip!
I’m an ICU nurse. If a patient starts acting crazy… we check blood gases. CO2 is normally what’s causing people to act up. People try to jump out of windows, become aggressive, rip off their BIPAP and refuse to put it back on even though they can’t breathe etc. We see it a lot with covid patients.
29:36 -> We actually did this experiment at Uni once (I'm studying biology). Well not with scuba diving gear but with the same premice, basically seeing how our bodies reacted to air gradually being enriched with CO2 as well as running out of oxygen without increasing the amount of CO2. It was quite interessting to see how fast your body reacted to an increase in CO2 levels and how you had no idea that the O2 levels decreased when CO2 levels did not increase. You could one second breath normally and the next pass out an die without ever noticing something was wrong. (obviously we were under supervision the whole time to make sure that does not happen)
I work around liquid nitrogen, and once i learned that if i ended up in a 100% nitrogen atmosphere i would just pass out within a few breaths without noticing anything was wrong. CO2 is suddenly much less scary.
I was ODH (oxygen depravation hazard) trained several times, to work near nitrogen purged spacecraft (which is truly terrifying--you just breath N2 like normal and blackout), and around liquid helium--which only gets loose in an accident, but we had miles of it to cool superconducting magnets: hit the floor and GTFO.
I am a recreational diver, no rebreathers, caves etc. One time I had an issue like this. I had multiple problems happening on a dive. A leak, a messed up mask, a buddy having ear problems and couple other minor things. I got myself stabilized, but I was breathing very shallow and quick. I was then agitated; the weird thing was all the issues were taken care of. I was stable and not having any issues in shallow water. I couldn't figure out what was going on. I surfaced and called the dive off for me. I was baffled and embarrassed. I am not a dive master or super diver, but I have close to 300 dives and never had this issue. Second dive, no issues with equipment, but in the back of my head I had questions. About 15 minutes in the same thing, agitation and wanting to surface. I went to the dive master and pulled him aside, (we where on a liveaboard for a week). He explained what he thought was happening. I was breathing too shallow and basically causing myself CO2 poisoning. He told me to breath out twice for every in breath. He took me on the next dive as my buddy. It was fine. Very simple, but I had no idea, and my head was screwing me.
I often think that, because CO2 is heavier than air, it can pool in the lower lung cavities. Proper trim while diving should help with this, but i wonder if a head down angle would clear this pooling faster if needed.
Why do I love watching these when I have no interest in actually diving myself? I find this weird. I am entertained and comforted by you guys for some reason. Welp keep it up.
it's the same for me, after watching a lot of videos, I'm even less interested in diving myself, because there is no safety zone for errors. Still the videos are sooo interesting, I can't stop watching
Hey me too, I'm claustrophobic and would be afraid to do it, but it's very interesting(also medical background). I figure you can never have too much knowledge right,? God Bless
I totally get it; I'm one of those people too. Before I met and fell in love with my first dog, I was planning to do a dive course. I'm glad I didn't because so much can go wrong especially when your mental faculties are also at risk. That's a deal-breaker for me so I'll stick to the simplicity of free-diving and snorkeling.
Woody, one time I was having issues lighting the pilot light on my water heater. I had done this many times before no problem. …..well this time , it wouldn’t light. I kept trying over and over. I was getting gassed without even realizing it. The more gas I inhaled, the more I felt stuck in a loop . I became even more determined to light that damn pilot light! It was strange. I can’t believe it but I didn’t realize in the moment what was happening. Evening though I’m very aware that it could happen. It effects your brain to where you deny it . It’s so weird. I was stuck in a loop of lightning the light. I felt very stubborn. At some point I gave up . Walked back into the house from the garage. Still feeling stubborn and stuck, I didn’t tell my husband that I couldn’t get the light lit. I sat down. My heart was racing. I was breathing heavy to try to slow my heart down. Finally it hit me what had happened. ..the interesting thing was how I was stuck in a loop doing the same thing over and over. And I was still thinking I was in control even though I felt different. It crept up on me. It sounds weird but I find that the be such a valuable lesson to me. I now sorta of understand how it feels to have this happen. To where as before I just thought it was a black and white issue. I feel normal, now I feel bad. But it wasn’t like that immediately. By time I started to realize what was happening , I was in too deep. Luckily , I stepped away and went inside. It took a good 30 minutes to an hour for me to feel normal again. I feel strangely lucky to have experienced that and be ok.
anyone else SO grateful that gus and woody actually listen to our comments and deliver the content we ask for!! and never fail to teach us (or at least me) something new every single time. always love coming home after a long day and seeing a video from dive talk,, couldn’t ask for a better way to end my day :)
When you breathe, even normally. you only exhale about 10 percent of the air in your lungs. When taking shallow breaths this is going to be even less. So it takes many breaths to replace the total volume and then you are basically trying to clean a bucket of dirty water by taking out one cup of dirty water and then putting one clean cup of water back in and repeating the process. The water will get clean over time but you will have to move many more cups than the total volume of the bucket. Hyperventillating in this analogy is like using the smallest possible cup to move water back and forth as fast as possible, when what you really want to do is is empty out the bucket in one go and completely refill it. To be clear that is why your CO2 levels will continue to rise even after bailing out, even if you could instantly completely swap out the air in your lungs it will still take sometime to clear the excess CO2 in your bloodstream, think of a runner who's just run a long race, he is going to continue to breathe hard for a while even after he's stopped running.
@@overcash007 It's very simple to show he is correct. Average human lung capacity is 6 liters, and average tidal volume (amount moved per breath) is 500 millilitres (0.5 liters). So with each breath the average human is only moving 1/12 of their total lung volume. Rodney is correct.
I had a hypercapnia experience on open circuit a few years ago. It was terrifying. I was working way too hard in cold water (around 50 F, diving wet, finning and breathing hard to stay warmer, which I no longer do) at around 120 feet. At first I felt slight nausea, but it quickly progressed to rapid breathing, racing pulse, and feeling like I just couldn't get enough air. My body wanted to bolt. I couldn't catch my breath. Panic was coursing through me. My air seemed bad somehow. It really felt like I was going to die. I was solo diving, so I had to sort all that out on my own while trying like hell to just keep mechanically breathing deeply and slowly making my ascent, which I did by staring intently at my computer and the sandy slope in front of me. It passed in a few minutes of really slowing down and breathing deeply. I would wager that being a bit narced played into the whole mental situation. I wouldn't recommend it. 😂
I used to do hard hat diving and a few times my hat would fog up due to my breathing cycle. Thankfully with hats we have a free flow mode. So after a while if I was doing heavy demand stuff, I just cracked it open and let it flow since I had an "unlimited" supply due to it all being supplied at the surface.
I’m so happy I found this channel. I haven’t dove yet but I have always wanted to learn. I’m held back by the money aspect. I have now set a goal for myself now that I’m doing a bit better financially. After I hit my weight goal (60 more pounds to go) I’m going to start taking scuba classes. In the mean time, I’m gonna learn as much as I can about diving and the community and save with each pound I loose (so far I have lost 15)
Good job! You can do this. My celebratory goal for my biz goals is the first scuba course to get certified. $580 here in Austin. It includes everything you need for the class. Save $5 or $6 bucks a day and we’ll have that class money in 100 days!
Called my ER physician friend about this. He told me two things: 1) often times people with elevated CO2 don’t feel like they’re getting air despite accelerated breathing (maybe why Kevin claimed that with the safety diver’s alternate), and 2) if this happens you want long exhales to really off-gas the CO2…really empty your lungs on each breath.
This happens because hemoglobin has 4 binding points which usually lock o2 in, when you get CO2, it binds to one of your points, and cannot be removed via your body's normal trick to displace the oxygen where it is needed. It causes you to feel as if you're suffocating because even though you have air in your blood, it can't be released (this will actually cause your blood cells to break down as well and form a new toxic compound that your body can filter over time). Extremely watered down, but 1) is very true. Long exhalations DO work, but it can be hard to remember that in highly confused states, which is usually where you will end up with CO2 poisoning because of the panic of the suffocation feeling.
I was about to write something similar. Fast breathing happening for the guy in the vid are shallow breaths. Meaning that the lungs never really get rid of the CO2 build-up, only replacing a small portion of the air. Your body is saying you already have to little air, so a long exhale is the last thing your body wants you to do, the one thing that would fix it. I think it is the same reason panicked divers sometimes forget to exhale in a torpedo (uncontrolled) ascend and blow their lungs. Firemen (Smoke divers) here were taught to do something called skip breathing, that can save air and calm you down, which is 2 inhales per exhale. This was shown to build up CO2 levels, so the method was changed to long inhale, 3 sec pause, long exhale, 3 sec pause, repeat. This reduces heart rate, but does get rid of the issue of CO2. This is something similar to what biathlon (ski shooting) athletes are trained to do as well.
The more you breath the more co2 is removed. This is the ONLY process to lower co2. The alveoli in the lung do the gas exchange. You must get your breath own to the bottom if your lung capacity.Quick shallow breaths wont work.
@@2011blueman Seriously? It is also a physiological response to hold your breath when you go underwater, yet scuba diving is a thing. Ask any scuba instructor if students have to mentally overcome this response when they begin their training.
@@Sheltered me too! But Gus and Woody are so entertaining so I stuck around. I have a fear of water that I’m working through and this channel is definitely helping. Becoming educated in a fun way 😆
I'm a veterinary surgical tech and I have worked for more than 1 person who was cheap and made us re-use any non-purple scrubber granuals on our anesthetic gas equipment!! I used to secretly dump the whole canister bc that made me really nervous! The anesthesia machine is a closed circuit rebreather but we used a non-rebreather open circuit attachment on small animals!
If I were in that position, I’d have anonymously reported that faculty to their governing board! That’s criminal & just because they are animals, it doesn’t give anyone the right to risk their lives. As an animal lover, this makes me so angry!! Thank you for not following their unsafe protocols!! 🎉
I love the way gus keeps looking back at woody during a controversial part of the video their viewing. You know gus values his opinion and is observing woody's reaction. I totally 100% understand this behavior as I do this all the time when showing someone (who's opinion I value) a new song I wrote (in my case since I'm a musician). Honestly everything about your guys' content is so refreshing. So glad I found your channel.
the scariest thing about respiration / gas issues in diving is that the diver is faced with a complex problem solving task **while their problem solving faculties are getting more and more impaired**. solving the issue with full control of your faculties is one thing...solving the problem while quickly becoming hypoxic or narc'd is a whole different animal.
I found you guys through Mr. Ballen lol. Watching his vids about underwater caves only enforced my fear of water bc so many dangers. But after binge watching you guys, I think diving would be on my bucket list....not too sure about caves though. Im more open to it. Im still wary of underwater darkness and the unknown 😣😣😣. Happy to support yall ❤
I'm pretty sure gus was the kid that would tell all the other kids not to go in the abandoned house but nobody listened and they all came out fine with a great story. Then would tell on them to his parents so all the other kids got in trouble from there moms when they got home that night
Yeah, Factboy says "hit that dislike 👎 button" on his more casual channels like "The Casual Criminalist" because it really doesn't matter whether you liked it or not it only matters that you actually hit A button.
@@cbracing808 Of course it matters for people watching weather they think the video is b.s. or truth, not just traction. A heavy dislike favouring ratio indicates somethings wrong in the info presented for the discerning viewer so they may proceed to watch with caution.
@@yugimotobutjacked3231yea im sad Woody is sensitive to the haters. He could be perfect and still have people saying negative things and disliking the video. Its impossible to please everyone and some people like hating on others to feel better about themselves. Focus on the majority who love Dive Talk.
Im not a diver , but I was always so fascinated with diving, cave diving etc and would occasionally stumble upon cool random videos Now having subbed to you guys I learned soooo much about diving that I hadn't a clue. Thanks alot guys
In veterinary medicine we use a non-rebreather system and an open circuit. The non-rebreather is used on small animals up to about 12 lbs. I have had co-workers be super lazy about changing the scrubber and it makes me INSANE! Nobody realizes how important it is to change it! A little bit of purple and I dump the whole thing 💜🦈
My claustrophobia would never allow me to dive and I don't understand half of the tech stuff but I love listening to you both...super interesting and fun 😃 ❤️🐳
You can forget cave diving, wreck diving etc, but, unless you have trouble donning a thermal insulating suit or holding a stage in your mouth, you should be ok in open water
If you want to try to tackle this; - gradually learn to use a scuba mask in a pool, putting your face under water, getting deeper over time - work with a dive instructor to have a longer time to get used to the dive equipment in the pool classes, then in a very shallow open water dive (maybe even only chest deep water to start) - next open water class would be deeper - ask the instructor to take their time teaching you and practicing mask clearing and calming techniques - have caring buddies who stay very close and encourage you - depending on your progress, maybe only do shallow (30 ft.), high visibility, warm water dives in calm conditions with trusted buddies I've seen people do these steps and progress to where the claustrophobia, at least while diving, totally goes away.
I'm a non-diver and over the past couple of months, I've learnt one helluva lot about diving (& caving), technique, health & safety issues, narcosis, open circuit, rebreathers etc, along with the names of caves and the top rescue guys! Your vids are truly addictive & I love the chemistry and banter between you two!
You guys are the kinda guys that could do a whole documentary on diving and we'd still be begging for more content! We cannot get enough !! We Love you guys keep up the good work 💙🤿
Just got off work to listen to a dive talk. I've never dived before. I don't like water. At all. But i love listening to this and listening on how to save your life in case need be. And i feel like I've learned a lot on this channel for if im ever in a situation in water, i might have a chance of survival. Lol
You don’t have to be underwater to experience hypercapnia. SEAL training includes breathing open circuit gas that contains CO2 while not underwater. I’ve done the poor man’s hypercapnia experience. I stuck a snorkel in a bag of dry ice. The dry ice was vaporizing into CO2 gas which I was inhaling through the snorkel. I built up CO2 more rapidly than you would with a rebreather. But, the symptoms should be similar. So long as you have another experienced diver watching you and you’re not underwater, I think it’s helpful to experience hypercapnia in a controlled environment. Mainly so you have a better idea of how it affects you. Because, different people get different symptoms in different orders.
Great video! It's also just a great reminder that for anything the safety procedures are there for a reason and how dangerous either cutting corners or incorrect training can be
While under hypercania, your body make you breath against your will (as you were mentionning, you just cant stop breathing). You cant/dont exhale enough, your body already ask more air and try to inhale again. It makes you use the dead space of your breathing apparel, preventing to bring fresh air to the zone into your lungs where CO2 would get out and exhale this CO2 air. As long as you can't exhale enough, you'll keep fastly breathing like hell without getting out of the CO2 from the blood and the air trapped in lungs. This is taught in CMAS N4 lessons for info, and it can also happen with open circuit if you're deep and making too much effort. As an early detection of this phenomena, it's advised to try just for a second to hold your breath. If you can't, you're hypercanic.
Guys, I feel I should say that you have the balance just right with this video. You've got a great channel and the commentary really hit the nail now! Great rapport. Keep it up.
Im a secondary teacher from the Uk and im absolutely hooked on your videos . I played and incorporated some segments from your videos into my lesson planning and my year 10 students are hooked to . Thank you for this awsome content 💜
I really enjoy all your videos. But I especially appreciate this one for the level of detail and very technical explanations. These kinds of discussions are the difference between surviving to dive again and being the subject of your next reaction video to an avoidable situation.
46 breaths a minute...the average is 12 - 20...anything above 25 is classed as laboured and cause for concern. And resusing the powder? Pfft, just shows how much SKY value their staffs lives to save a couple of quid. I love how woody says "you swarm em" 🤣 I'd appreciate being swarmed by my dive team if I was struggling, I'd feel taken care of and not alone. Pure teamwork💪🏻 Another great video guys! I loved it. I'm up at 4am nearly in tears with a dislocated knee and you've kept my mind pre occupied❤🤣 take care guys xxx
As an RN , CCRN, for thirty years, you guys present this info great!! Of course, as an ICU RN, I deal with ventilators and these oxygen delivery mechanisms hourly. But you two are great do for non medical viewers!! Love y'all and be careful always!!
You guys are great, and Gus’ ability to anticipate Woody’s questions and have someone join them on the pod, or have reached out to someone before hand for the answers is excellent. I appreciate the respect and appreciation you guys have for safety procedures and protocol. Awesome video.
Hi Gus and Woody, I did my first Pedi classes last week - I hurt my ears - so at home in bed recovering and loving your channel. Learning heaps - what a brilliant channel. I learnt from you guys to start equalising early and at the beginning of the descent - at shallow depth to prevent ear trauma. Looking forward to learning tonnes over the next three months it will take to heal. Thank you so much for your incredible help.
When in doubt, you must bail out! 💯 Not a bad motto in general, but seems spot-on for rebreather divers. 🙂 Great episode guys! Very interesting and informative, best rebreather seminar ever! 🤓👏 Without Dive talk, I'd have no idea what a KISS rebreather is... instead I can explain how one works, and what mistake to avoid when packing one's scrubbing cannister! AND, I know how KISS rebreathers differ from others. 😁🤘Hope KISS are makin' it rain up in there for you two ambassadors. 💸💰👍
Holy cow, what a unique fresh and entertaining channel. I'm 31 and have never had an interest in diving. I'm a few videos down the rabbit hole with you as my guide. I gotta say, well done! I'm a total fan. Just got membership
Quality video as always guys. I know you have mentioned it before but videos like this really bring into focus the importance of not only getting training, but making sure it is the correct training. Maybe a link to the video where you talked about what to look for when finding an instructor would be good or even another focused vid just on researching the correct training you need. I know it may be boring for some but would be hugely beneficial to the ones that need it and you could just put the link to it in your vids and mention it when relevant. Idk maybe that is too much. I was just thinking out loud.
Hel here-so great that you can bring in Mike Young to explain why no sensor yet and Dr Doug Ebersole for explanation of what is happening in C O 2 hit!Access to the horse's mouth,the Masters! Excellent,informative video and please don't think we Brits are weird cheapskates, just a poorly informed instructor passing on bad practice that could kill you! Glad the camerman survived!
I've known individuals that did this, or variations thereon. But I'd never heard of anyone actually teaching it. A lot of folks will push the duration on a scrubber somewhat, with seemingly far better results. Though it's still a roll of the dice. About breathing under higher CO2 you can't entirely fight it, but with focus you can adjust to taking deeper somewhat slower breaths. It won't really reduce your gas consumption in the moment, but does seem to help get back to a normal pattern a bit faster. And yes, you can get CO2 buildup on open circuit just like on the surface when you're exerting. You can go through a lot of gas, and get to breathing so hard you try to breathe more than the reg will deliver. When working hard underwater you need to take more and more frequent breaks to help stay out of that zone. Areas of "bad air" high CO2 also occur in dry caves and can be dangerous, though in most cases the symptoms are easy to spot. If you want to experience that, there's nothing that says you have to be in the water. Easily accomplished on the couch, and much safer.
20:18 He does have “normal” sized bailout tanks, they say it, but doesn’t get to it. For some reason they aren’t carrying their bailout tanks on them, but must have tied them to a line or something. The thing is, on every rebreather you can bailout to your diluent and use your rebreather on open circuit breathing directly from your diluent without having the gas loop through your scrubber. Usually you’d use this function as a mean of having something to breath while your sorting out your bailout tanks, or if your near the end of your dive, close to the surface and without any more deco to do, as your diluent usually is contained in a very small tank, usually between 2 to 4 litres, and as such is used very fast. It’s the same principle with the kiss rebreathers Woody and Gus use, but their diluent is contained in a bigger tank.
Lots of scary things about this video! But lack of judgement due to his impairment really hits hard. Even if you're the best, highly trained, certified diver with expensive equipment, that mental fog from the CO² hit can cause you to underestimate the danger you are in. It reminds me a little of Nitrogen narcosis. If you lose your ability to make good decisions at depth, you could easily die.
I've had a co2 hit, which is why I switched to a rebreather with a co2 monitor, as per a previous conversation we had here. My experience was similiar to what Doug described for around 10 minutes, but on top of that, I felt sick, nauseous and fatigued for well over half an hour. And while those effects aren't fatal like hypercapnia itself can be, they're certainly not good under water either.
@@E_Clampus_Vitusit's because CO2 sensors aren't reliable enough right now for rebreathers. It's in the video where Gus mentioned that question and what Mike Young said about it.
I am a master cave diver with knowledge of every cert.....I also have never touched a body of water in scuba gear. Thank you for the master class dive talk!...
My 2 cents, as a rebreather diver who has experienced a CO2 hit: once you bail out to open circuit your CO2 level is not going to increase, but when breathing VERY shallow rapid breaths you aren't getting rid of the existing CO2 very quickly. It's not a function of being on the loop vs OC, even on the surface it would take a significant amount of time to flush that CO2 out of your system.
Yeh it worries me that diving instructors don't actually know this, I don't dive but I have common sense and my common sense tells me how can U possibly build up more CO2 if there is none in the air Ur breathing.. I'm obviously talking about nitrox or trimix not regular compressed air though (which is what they were talking about because Gus said he asked Doug that)
Also worries me when they said that's another thing we should think about when gas planning because it seems as though I'd want to make sure I had enough bail out gas to make it out alive if I did get a CO2 hit and was breathing 5 litres per minute..
Aloha. Thank for the video. I didn’t read all comments. As a deep diver very important things to do when starting over breathing, 1 exhale more to reduce your co2 level, 2 stop moving making effort ( swimming) because more you move more you create co2. Ask for assistance to do your ascent !
I just watched Monty Hall’s Blue Hole dive I think from like 5-7 yrs ago? In it, they were going to use rebreathers and practiced day before. The cameraman actually had a filter problem so he was breathing in CO2 and he needed help. Luckily they hadn’t gone far down. Then Monty does a test in a lab and they recreate what happened to cameraman. Monty was doing that super fast breathing. It was a good example of what happened. I understand more now what a rebreather is because I don’t dive but it’s nice to know what the equipment looks like that you guys talk about! Nice vid guys!
Hey guys, I had an interesting conversation with my dive instructor about the kids being rescued in that Taiwan cave a few years ago. I would love a video from you guys about what happened there.
Best kind of safety training for anything needs to give people a good enough functional understanding of the chemistry, the mechanics, or the physics of what they're dealing with that they can't just invent their own seemingly "smarter" protocols for how to operate the device. If they had been taught the sorb reaction progresses as a single layer throughout the scrubber they'd have known that mixing it all up was just as bad as poking a straw through it.
So true!I like when I explain things to my GF whilst using physics, engineering, and chemistry. Just had a conversation about dimethyl Mercury vs regular mercury.
Sometimes tweaking it on your own as necessary. Protocol was to mix it back in 2004 in this video. That is how the experts taught people how to do it. These divers anyway and I'm sure they're not the only one. It takes time to figure things out and unfortunately the first people in a new technology or even way of doing things are simply Test Dummies. You have to know what not to do before you know what exactly to do and you learn that through trial and error. Unfortunately rmd through manufacturers doesn't always do a thorough enough job and the consumers are the ones figuring out the details for the producers to tweak. Sometimes when you have a few hundred devices out there being tested doesn't give you the full picture until you have thousands of them out there being used in real-world everyday scenarios
Dive talk THANKS A LOT FOR EXPLAINING THE RE-BREATHER PROCESS!! Anyone could understand the way you guys explained it...keep up the good videos and we'll keep watching!
I have been binge watching these videos for the last week i have no interest in diving but dang i just love watching you guys and learning about all of this but it has definitely reassured me that I'm never getting in the water again lmao i hope you guys always stay safe we need yall here making these video's keep up the great work guys :)
I’m stuck home on quarantine, I’ve been watching your videos non-stop. I was PADI Open Water certified in 2007 in Curaçao and I was so lucky to have an amazing team of instructors, it was a school trip and they had gone with the same team of people for over 15 years. It was amazing, it was the best thing I’ve done! I was so lucky to have nannied for a family who were going on a trip to get their advanced open water certification and they wanted to include me on their vacation. I am hyped on trying for cave after seeing your passion for it, I was too afraid from misinformation online 😞 - I love your channel! Thank you!
That almost went from a practice body recovery drill, to an actual body recovery drill. He was surrounded by all The technology and help one could ask for. If he was diving alone, or diving with just one dive buddy, he would probably be dead.
Another good one guys. I think Woody pushing it in a pool with support would be a mega video and give Rebreather divers a real time experience to be aware of
Thumbs up for Woody and Gus! Let’s give them a 100% likes for once- they’ve earned it! Update: 8 people are jerks lol! (Jk, no one attack me, everyone can have an opinion). Unfortunately for Woody, I don’t think any YT vid has no dislikes. 😕
29:20 If you want to feel a CO2 hit then all you need is high intensity exercise for 20-30 minutes. 20 hard mins on a bike your SAC rate will go crazy, your lungs will be screaming and you'll be gasping for air thinking you might die.
Aaawww So Sweet @24:16 That's What all Divers should Live by Woody.. "Never Dive Alone" Woody and Gus Australia Here, I Can Not Swim Petrified of Deep Water. Yet I'm watching Your Video's Of Diver's Nearly Dying of Drowning. Listening to your Comments is in one Ear out the Other. There is a Pool in my Backyard it is an in ground pool and I Have Not set Foot in it. I'm ok in the Shower Not a Bath. That is Showing you Both how Calming your Making this all Sound, Even though I don't Understand anything. Sending you Both and Your Families Kindest Thoughts from Australia. 🌏🐨🦘😇
Woody: *asks question* Gus: "I read your mind, and I have the answer you seek." This is fascinating stuff that even non-divers like myself can enjoy. And Woody will be pleased to know that 3 months later, this video still has no downvotes (I can see dislike counts on videos with a browser add-on).
Everytime I watch one of your videos I get more educated and the world of diving which I love so much but I haven't had the opportunity to dive in many years but I still love learning more so your videos are very helpful when I do dive in the future. Thank you for these!
Wow those guys were trained/taught to keep old scrubber and save a few bucks 🤦🏼♂️. Gus “Just repack it bro” I knew absolutely nothing about rebreathers before watching this video. Although technical, I still found it very interesting. 👍🏼👍🏼
I go between 4 channels, You guys, Bedtime Stories, That Chapter and MrBallen. You guys are the only channel I watch where I feel that my voice is heard and you guys actually care. Thank you for all you do!
I'm not a diver, don't plan on learning to dive. I am an ex royal navy Submarine veteran so I have an interest in the water in general but I love just putting these videos on and chillin, watching and learning Great!
New diver here from Long Island working on completing open water now...your videos are helping me understand so much more about the diving community and are extremely informative and entertaining! I get more excited to dive every time I watch your videos. Thanks for all you do and for the great content every week 😎
You can experience a CO2 hit without having to risk it in a pool. Just breath into a sealed plastic bag and keep breathing in and out without letting any fresh air into the bag. Within 10 to 15 breaths you will already start to feel the effects. Your body will already start wanting to pull the bag away to get fresh oxygen into your system. And then you realize even after you take the bag away and do breath fresh air, it takes a few minutes for the effects to go away.
@@vashisl33t I didn't say put your whole head in the bag, lol. Just put it up to your mouth goofball. You would need to keep breathing like that far FAR past where your instincts are pulling the bag away for you in order to come close to passing out. You won't pass out. And even in the small sliver of a chance you do, your hand falls away from your mouth and your breathing oxygen again. Do you panic everytime someone breathes into a paper bag while having anxiety and tell them they are going to die ? Relax. You can do things safely within reason that doesn't put you into danger.
I guess stuff like this happens cause people just doesnt think through these things, they are just like 'ye doesnt look that bad i can reuse a part of it...' thats just common sense and how most people would think about it. But if you look closley and calculate it you notice that youre saving only 1dollar per dive for risking your life! Imagine being in a cave at this situation... It shows again how good or even important it is to be mindful and understand evrything arround your gear, and also that you guys talk about these things. So thank you for that and it was very intressting to see how Rebreathers function. Keep up the great work :)
I'm not a rebreather driver, but I have had asthma since I was very young. One of the things I learned early on was that quick, shallow breathing doesn't get oxygen in your body; and the most important thing to do when having an asthma attack is to breathe as deeply as possible
Goes for many situations in life like if you get a severe panic attack also slow and deep breaths is the key to calm down and help to get the panic attack under control. We can help our body in many ways by just trying to be calm and breath. Now I don't have asthma but I used to work as a paramedic and met many patients with asthma and its really hard to see a person struggle so hard to breath, but I'd like to remind everyone that has asthma to always have their inhalor with them at all times. Even if the inhalor might not help completely sometimes and the patient need stronger medicines and treatment it will help to improve and the person struggling with breathing difficulties and make it a bit easier for them until the ambulance arrives. I hope you are ok!
So why didn't the two people that were with him when he switched over to his tank immediately take him up? At that point he was surely in trouble. Sounds to me like he doesn't like to take responsibility for screwing up. So it didn't get him this time, but if he doesn't rethink his training; it will.
I can see by your facial expressions you were thinking this too, but this guy has a huge ego. Refuses to admit he was not in control after the co2 hit.
I'm not convinced it's his ego talking. My understanding is since he confesses confusion, and probably guesses that he's hit, he then tells the story of how that hit did not allow him to think straight, therefore keep believing that he is in control of the situation even though he clearly isn't. And he says that probably to emphasise how grave the situation really was for him. That's my opinion
If the other divers are still on the loop of the ccr it’s hard to do an oral inflation. So they need to get of the loop first, go in to OC or BO mode and then inflate the buddies bcd. Experienced divers will maybe able to manage that without going OC but this is beyond my level
We learned so much from this video. No trying hypercapnia Woody!!! That animation video really helped me understand sort of how the rebreathers work and so glad you guys have such amazing friends to be able to ask questions and share that knowledge with us. Before long you guys will be running your own scuba school!!! Thanks as always for another great video you guys!!
Pretty scary how the diver is so adamant he was in control even after all the facts and expert opinions are clear. Almost seems prideful or egotistical, cant say i made a mistake (reusing scrubber), and didn't have proper equipment (proper size bailout tank). One thing your channel and Mr. Ballens have tought me: ego and diving doesn't mix to well 😆
15:47 this segment is what i was mainly pointing at about "ego". He still seems convinced it was a controlled ascent. Being in a haze from C02 and running out of your own air, relying on two different divers air (he even rejected a good air source from panic) doesn't seem so controlled. I dont even blame him for the accident, this video made it clear that there was a problem with the teaching/culture of diving at this time and region (the shocking number of divers that thought reusing sorb was a viable option). Point is: Just seemed like he was downplaying it (saying he was in control), which i attributed to ego. Just my worthless non diver opinion tho 😆
@@GapingClam he didnt say he was in control. go watch it again he remembers it being a totally normal ascent. he was so fogged out what he remembers is it going well and the ascent was fine only realizing after because of the video
@@dominicklittle9828 umm i gave u a time stamp... He says "i do believe, and i still believe now, that we did it in a controlled manner" Edited to get quote right
@@PaulAnthonyDuttonUk how is it just emphasis? He literally states that even now believes he was in control, even though the experts disagree... Thats not emphasis thats him clearly saying he disagrees with the experts
woody i think you missed the part where they said they were taught incorrectly. they not saying this is how it should be done. they are admitting its wrong. love how passionate woody gets, he just wants to share his knowledge and teach. i highly doubt they did this to save money they were just taught wrong. i can finally relate aswell to the body as a good co2 sensor aand trusting yourself. I used to load lorries via overhead crane and we had these dodgy barriers that were to go up to the lorry on the sides so if we fell the barrier would save us...however like the co2 sensor they were unreliable and would move, i told health and safety i rather no barrier forcing me to be cautious than a false sense of security of a barrier knowing if i did fall my weight would push the barrier and id end up between the barrier and lorry.
I don’t know much about rebreathers, but I assume that you have some instrument that will indicate when you have a problem with your oxygen, right? Now my next question is, if you have an issue with your oxygen, does it mean by default that your CO2 levels will go up? If the answer to this 2 questions is YES, then per my logic (which might be filled with missing information), then you don’t need a CO2 indicator. Your oxygen indicator will alarm you of a problem with oxygen, by default you CO2 levels should rise (plus your own “body” indicator) and you’ll switch to your bail out. I would love to know if my logic is correct, and if not, to learn more about why. Your channel is very entertaining for me to watch, thanks! And by the way, I give you a 100% thumbs up 👍. At least so far on all the videos I watched.
Im glad I found this Chanel! Not looking to dive but after watching Mr. Ballens videos I found yall and its so cool and informative to find out how it is seen from the eyes of veteran divers
![Blox Fruits Dragon Rework Update [Full Stream]](http://i.ytimg.com/vi/EqDAp8udhm0/mqdefault.jpg)
Hello! I am a respiratory care practitioner who is also a diver. So you are right! Carbon dioxide acts as a trigger to ventilate because we possess chemoreceptors in different areas of our body that react to oxygen, carbon dioxide and hydrogen (hydrogen ions being the main source of ventilatory response. Carbon dioxide possesses a value of hydrogen ions so you can argue that the reaction to carbon dioxide is secondary). Oxygen, in one reaction, actually works as a mechanism to dull chemoreceptor response to hydrogen ions, therefore, switching to a lower percent oxygen or higher percent oxygen at a given level of hypercapnia will have an inverse relationship with your respiratory rate (lower [oxygen]=higher resp. rate, higher [oxygen] lower resp. rate) but this mechanism I have not seen in action in healthy individuals, but is pronounced with people who have chronic lung disease. Sorry to be writing an essay, but to answer your question on building CO2 while working to eliminate CO2 can be answered in terms of the degree of increased work of breathing vs ventilatory support. So if your work of breathing is greater than the amount of support you have then you will go into respiratory failure (Our natural support is our muscles of inspiration i.e. the diaphragm, internal intercostals). If your support is equal to or outperforms your work of breathing your urge to ventilate and work of breathing will tend to diminish after 5-10 minutes as the doctor was saying (assuming you have no chronic lung disease or anything like that). So since the only airway support you have underwater is your regulator and muscles to inhale, if you have a CO2 hit AND you also have venturi/rotator knob adjustment then that may help relieve some of the work you have to produce with your muscles alone, although I haven't heard anything to support this. But after analyzing many blood samples from patients with acute non-chronic hypercapnia, I can get a high level of CO2 (PaCO2) initially and after I put them on a BIPAP or invasive ventilator I will usually see a reduction to normal levels within 10 minutes. I hope this helped and I didn't butcher any explanations.
Oh and also. Woody and Gus, love your videos, they definitely have made me a more conscious diver. Don't change a thing. You guys rock and looking forward to the next dive talk trip!
Sorry for the long story book as well!
Thanks for this info! I use my intercostals to fine-tune my buoyancy when I need critical control. It's taxing caloricly, but adds needed precision.
I’m an ICU nurse. If a patient starts acting crazy… we check blood gases. CO2 is normally what’s causing people to act up. People try to jump out of windows, become aggressive, rip off their BIPAP and refuse to put it back on even though they can’t breathe etc. We see it a lot with covid patients.
Woody asks a question, and Gus has the answer prepared (or a surprise guest on-hand). Just great stuff!
I knew it was coming :)
@@DIVETALK great stuff guys!
lol, I love it when that happens. Whenever i hear Gus start to say, "well, I went and called x--" I'm like Gasp!! :D
Love when they do this!
@@DIVETALK Honestly, I do love it. Knowing your boy is unlike anything else
29:36 -> We actually did this experiment at Uni once (I'm studying biology). Well not with scuba diving gear but with the same premice, basically seeing how our bodies reacted to air gradually being enriched with CO2 as well as running out of oxygen without increasing the amount of CO2. It was quite interessting to see how fast your body reacted to an increase in CO2 levels and how you had no idea that the O2 levels decreased when CO2 levels did not increase. You could one second breath normally and the next pass out an die without ever noticing something was wrong. (obviously we were under supervision the whole time to make sure that does not happen)
I work around liquid nitrogen, and once i learned that if i ended up in a 100% nitrogen atmosphere i would just pass out within a few breaths without noticing anything was wrong.
CO2 is suddenly much less scary.
I was ODH (oxygen depravation hazard) trained several times, to work near nitrogen purged spacecraft (which is truly terrifying--you just breath N2 like normal and blackout), and around liquid helium--which only gets loose in an accident, but we had miles of it to cool superconducting magnets: hit the floor and GTFO.
I am a recreational diver, no rebreathers, caves etc. One time I had an issue like this. I had multiple problems happening on a dive. A leak, a messed up mask, a buddy having ear problems and couple other minor things. I got myself stabilized, but I was breathing very shallow and quick. I was then agitated; the weird thing was all the issues were taken care of. I was stable and not having any issues in shallow water. I couldn't figure out what was going on. I surfaced and called the dive off for me. I was baffled and embarrassed. I am not a dive master or super diver, but I have close to 300 dives and never had this issue. Second dive, no issues with equipment, but in the back of my head I had questions. About 15 minutes in the same thing, agitation and wanting to surface. I went to the dive master and pulled him aside, (we where on a liveaboard for a week). He explained what he thought was happening. I was breathing too shallow and basically causing myself CO2 poisoning. He told me to breath out twice for every in breath. He took me on the next dive as my buddy. It was fine. Very simple, but I had no idea, and my head was screwing me.
I often think that, because CO2 is heavier than air, it can pool in the lower lung cavities. Proper trim while diving should help with this, but i wonder if a head down angle would clear this pooling faster if needed.
Why do I love watching these when I have no interest in actually diving myself? I find this weird. I am entertained and comforted by you guys for some reason. Welp keep it up.
Me too, I don't even know how to swim properly lol, but stil watch their videos a lot.
it's the same for me, after watching a lot of videos, I'm even less interested in diving myself, because there is no safety zone for errors. Still the videos are sooo interesting, I can't stop watching
Me too, I don’t even swim but I like to listen those guys👍🥰
Hey me too, I'm claustrophobic and would be afraid to do it, but it's very interesting(also medical background). I figure you can never have too much knowledge right,? God Bless
I totally get it; I'm one of those people too. Before I met and fell in love with my first dog, I was planning to do a dive course. I'm glad I didn't because so much can go wrong especially when your mental faculties are also at risk. That's a deal-breaker for me so I'll stick to the simplicity of free-diving and snorkeling.
When I heard “bailing out” in your stories I automatically thought the diver was getting out the water. Lol. Glad you explained that one. 👍🏻
By the way, a thumbs up means "abort the dive, surface immediately" :)
How do you get out the water at sixty feet below
@@mikerollo8653 go to the surface. 🤔
Same. Learn some thing new every day 😌.
Woody, one time I was having issues lighting the pilot light on my water heater. I had done this many times before no problem. …..well this time , it wouldn’t light. I kept trying over and over. I was getting gassed without even realizing it. The more gas I inhaled, the more I felt stuck in a loop . I became even more determined to light that damn pilot light! It was strange. I can’t believe it but I didn’t realize in the moment what was happening. Evening though I’m very aware that it could happen. It effects your brain to where you deny it . It’s so weird. I was stuck in a loop of lightning the light. I felt very stubborn. At some point I gave up . Walked back into the house from the garage. Still feeling stubborn and stuck, I didn’t tell my husband that I couldn’t get the light lit. I sat down. My heart was racing. I was breathing heavy to try to slow my heart down. Finally it hit me what had happened. ..the interesting thing was how I was stuck in a loop doing the same thing over and over. And I was still thinking I was in control even though I felt different. It crept up on me. It sounds weird but I find that the be such a valuable lesson to me. I now sorta of understand how it feels to have this happen. To where as before I just thought it was a black and white issue. I feel normal, now I feel bad. But it wasn’t like that immediately. By time I started to realize what was happening , I was in too deep. Luckily , I stepped away and went inside. It took a good 30 minutes to an hour for me to feel normal again. I feel strangely lucky to have experienced that and be ok.
YIKES!
That's really interesting
anyone else SO grateful that gus and woody actually listen to our comments and deliver the content we ask for!! and never fail to teach us (or at least me) something new every single time. always love coming home after a long day and seeing a video from dive talk,, couldn’t ask for a better way to end my day :)
Thank you Beth!
When you breathe, even normally. you only exhale about 10 percent of the air in your lungs. When taking shallow breaths this is going to be even less. So it takes many breaths to replace the total volume and then you are basically trying to clean a bucket of dirty water by taking out one cup of dirty water and then putting one clean cup of water back in and repeating the process. The water will get clean over time but you will have to move many more cups than the total volume of the bucket. Hyperventillating in this analogy is like using the smallest possible cup to move water back and forth as fast as possible, when what you really want to do is is empty out the bucket in one go and completely refill it. To be clear that is why your CO2 levels will continue to rise even after bailing out, even if you could instantly completely swap out the air in your lungs it will still take sometime to clear the excess CO2 in your bloodstream, think of a runner who's just run a long race, he is going to continue to breathe hard for a while even after he's stopped running.
Incredible analogy, Rodney. Thank you for that.
your numbers seem a little made up
@@overcash007 It's an analogy to explain how a process works. It's not scientific notation.
Excellent analogy. Hard to play catch up with abnormal physiology.
@@overcash007 It's very simple to show he is correct. Average human lung capacity is 6 liters, and average tidal volume (amount moved per breath) is 500 millilitres (0.5 liters). So with each breath the average human is only moving 1/12 of their total lung volume. Rodney is correct.
I had a hypercapnia experience on open circuit a few years ago. It was terrifying. I was working way too hard in cold water (around 50 F, diving wet, finning and breathing hard to stay warmer, which I no longer do) at around 120 feet. At first I felt slight nausea, but it quickly progressed to rapid breathing, racing pulse, and feeling like I just couldn't get enough air. My body wanted to bolt. I couldn't catch my breath. Panic was coursing through me. My air seemed bad somehow. It really felt like I was going to die. I was solo diving, so I had to sort all that out on my own while trying like hell to just keep mechanically breathing deeply and slowly making my ascent, which I did by staring intently at my computer and the sandy slope in front of me. It passed in a few minutes of really slowing down and breathing deeply. I would wager that being a bit narced played into the whole mental situation. I wouldn't recommend it. 😂
Thanks for sharing!
the one they said would comment lol 19:00
I used to do hard hat diving and a few times my hat would fog up due to my breathing cycle. Thankfully with hats we have a free flow mode. So after a while if I was doing heavy demand stuff, I just cracked it open and let it flow since I had an "unlimited" supply due to it all being supplied at the surface.
I’m so happy I found this channel. I haven’t dove yet but I have always wanted to learn. I’m held back by the money aspect. I have now set a goal for myself now that I’m doing a bit better financially. After I hit my weight goal (60 more pounds to go) I’m going to start taking scuba classes. In the mean time, I’m gonna learn as much as I can about diving and the community and save with each pound I loose (so far I have lost 15)
Good job! You can do this. My celebratory goal for my biz goals is the first scuba course to get certified. $580 here in Austin. It includes everything you need for the class. Save $5 or $6 bucks a day and we’ll have that class money in 100 days!
Called my ER physician friend about this. He told me two things: 1) often times people with elevated CO2 don’t feel like they’re getting air despite accelerated breathing (maybe why Kevin claimed that with the safety diver’s alternate), and 2) if this happens you want long exhales to really off-gas the CO2…really empty your lungs on each breath.
This happens because hemoglobin has 4 binding points which usually lock o2 in, when you get CO2, it binds to one of your points, and cannot be removed via your body's normal trick to displace the oxygen where it is needed. It causes you to feel as if you're suffocating because even though you have air in your blood, it can't be released (this will actually cause your blood cells to break down as well and form a new toxic compound that your body can filter over time).
Extremely watered down, but 1) is very true.
Long exhalations DO work, but it can be hard to remember that in highly confused states, which is usually where you will end up with CO2 poisoning because of the panic of the suffocation feeling.
I was about to write something similar. Fast breathing happening for the guy in the vid are shallow breaths. Meaning that the lungs never really get rid of the CO2 build-up, only replacing a small portion of the air. Your body is saying you already have to little air, so a long exhale is the last thing your body wants you to do, the one thing that would fix it. I think it is the same reason panicked divers sometimes forget to exhale in a torpedo (uncontrolled) ascend and blow their lungs.
Firemen (Smoke divers) here were taught to do something called skip breathing, that can save air and calm you down, which is 2 inhales per exhale. This was shown to build up CO2 levels, so the method was changed to long inhale, 3 sec pause, long exhale, 3 sec pause, repeat. This reduces heart rate, but does get rid of the issue of CO2. This is something similar to what biathlon (ski shooting) athletes are trained to do as well.
The more you breath the more co2 is removed. This is the ONLY process to lower co2. The alveoli in the lung do the gas exchange. You must get your breath own to the bottom if your lung capacity.Quick shallow breaths wont work.
@@2011blueman Simply not true. It is difficult, and everything in you will tell you otherwise, but you CAN control your breathing.
@@2011blueman Seriously? It is also a physiological response to hold your breath when you go underwater, yet scuba diving is a thing. Ask any scuba instructor if students have to mentally overcome this response when they begin their training.

Thanks for listening
I'm a veterinary surgical tech and I have worked for more than 1 person who was cheap and made us re-use any non-purple scrubber granuals on our anesthetic gas equipment!! I used to secretly dump the whole canister bc that made me really nervous! The anesthesia machine is a closed circuit rebreather but we used a non-rebreather open circuit attachment on small animals!
If I were in that position, I’d have anonymously reported that faculty to their governing board! That’s criminal & just because they are animals, it doesn’t give anyone the right to risk their lives. As an animal lover, this makes me so angry!!
Thank you for not following their unsafe protocols!! 🎉
I love the way gus keeps looking back at woody during a controversial part of the video their viewing. You know gus values his opinion and is observing woody's reaction. I totally 100% understand this behavior as I do this all the time when showing someone (who's opinion I value) a new song I wrote (in my case since I'm a musician).
Honestly everything about your guys' content is so refreshing. So glad I found your channel.

I catch myself smiling and find that y’all have perfect buoyancy not only in the water but in life as well. Ty. Biloxi,MS
the scariest thing about respiration / gas issues in diving is that the diver is faced with a complex problem solving task **while their problem solving faculties are getting more and more impaired**. solving the issue with full control of your faculties is one thing...solving the problem while quickly becoming hypoxic or narc'd is a whole different animal.
reminds me of fighter pilots
I found you guys through Mr. Ballen lol. Watching his vids about underwater caves only enforced my fear of water bc so many dangers. But after binge watching you guys, I think diving would be on my bucket list....not too sure about caves though. Im more open to it. Im still wary of underwater darkness and the unknown 😣😣😣. Happy to support yall ❤
Sometimes i feel like Gus is the only one keeping Woody safe and sound from his experiment ideas 🤣 thank u Gus for your public service.
Hahaha you are welcome
Woody is playing 'devils advocate', I recon.
I'm pretty sure gus was the kid that would tell all the other kids not to go in the abandoned house but nobody listened and they all came out fine with a great story. Then would tell on them to his parents so all the other kids got in trouble from there moms when they got home that night

@@cbracing808 Of course it matters for people watching weather they think the video is b.s. or truth, not just traction. A heavy dislike favouring ratio indicates somethings wrong in the info presented for the discerning viewer so they may proceed to watch with caution.

Thanks!
Im not a diver , but I was always so fascinated with diving, cave diving etc and would occasionally stumble upon cool random videos
Now having subbed to you guys I learned soooo much about diving that I hadn't a clue.
Thanks alot guys
In veterinary medicine we use a non-rebreather system and an open circuit. The non-rebreather is used on small animals up to about 12 lbs. I have had co-workers be super lazy about changing the scrubber and it makes me INSANE! Nobody realizes how important it is to change it! A little bit of purple and I dump the whole thing 💜🦈
Doesn't Non-rebreathing system specifically mean there is no canisters and it's just flushing with oxygen?
Thats terrible 😭 People are entrusting their beloved pet and some vets don't care.
The way Gus says "omelet", that was great!!
My claustrophobia would never allow me to dive and I don't understand half of the tech stuff but I love listening to you both...super interesting and fun 😃 ❤️🐳
You rock!
You can forget cave diving, wreck diving etc, but, unless you have trouble donning a thermal insulating suit or holding a stage in your mouth, you should be ok in open water
Me too!!!
If you want to try to tackle this;
- gradually learn to use a scuba mask in a pool, putting your face under water, getting deeper over time
- work with a dive instructor to have a longer time to get used to the dive equipment in the pool classes, then in a very shallow open water dive (maybe even only chest deep water to start)
- next open water class would be deeper
- ask the instructor to take their time teaching you and practicing mask clearing and calming techniques
- have caring buddies who stay very close and encourage you
- depending on your progress, maybe only do shallow (30 ft.), high visibility, warm water dives in calm conditions with trusted buddies
I've seen people do these steps and progress to where the claustrophobia, at least while diving, totally goes away.
@@betsybarnicle8016 Thank you, very helpful!
I'm a non-diver and over the past couple of months, I've learnt one helluva lot about diving (& caving), technique, health & safety issues, narcosis, open circuit, rebreathers etc, along with the names of caves and the top rescue guys! Your vids are truly addictive & I love the chemistry and banter between you two!
You guys are the kinda guys that could do a whole documentary on diving and we'd still be begging for more content! We cannot get enough !! We Love you guys keep up the good work 💙🤿
Just got off work to listen to a dive talk. I've never dived before. I don't like water. At all. But i love listening to this and listening on how to save your life in case need be. And i feel like I've learned a lot on this channel for if im ever in a situation in water, i might have a chance of survival. Lol
YES TWO FAVORITE RUclipsRS IN THE SAME MORNING !!! BEST MONDAY EVER Dive talk n mrballen !
You don’t have to be underwater to experience hypercapnia. SEAL training includes breathing open circuit gas that contains CO2 while not underwater.
I’ve done the poor man’s hypercapnia experience. I stuck a snorkel in a bag of dry ice. The dry ice was vaporizing into CO2 gas which I was inhaling through the snorkel. I built up CO2 more rapidly than you would with a rebreather. But, the symptoms should be similar.
So long as you have another experienced diver watching you and you’re not underwater, I think it’s helpful to experience hypercapnia in a controlled environment. Mainly so you have a better idea of how it affects you. Because, different people get different symptoms in different orders.
Great video! It's also just a great reminder that for anything the safety procedures are there for a reason and how dangerous either cutting corners or incorrect training can be
While under hypercania, your body make you breath against your will (as you were mentionning, you just cant stop breathing). You cant/dont exhale enough, your body already ask more air and try to inhale again. It makes you use the dead space of your breathing apparel, preventing to bring fresh air to the zone into your lungs where CO2 would get out and exhale this CO2 air. As long as you can't exhale enough, you'll keep fastly breathing like hell without getting out of the CO2 from the blood and the air trapped in lungs.
This is taught in CMAS N4 lessons for info, and it can also happen with open circuit if you're deep and making too much effort. As an early detection of this phenomena, it's advised to try just for a second to hold your breath. If you can't, you're hypercanic.
Guys, I feel I should say that you have the balance just right with this video. You've got a great channel and the commentary really hit the nail now! Great rapport. Keep it up.
Much appreciated!
Im a secondary teacher from the Uk and im absolutely hooked on your videos . I played and incorporated some segments from your videos into my lesson planning and my year 10 students are hooked to .

I really enjoy all your videos. But I especially appreciate this one for the level of detail and very technical explanations. These kinds of discussions are the difference between surviving to dive again and being the subject of your next reaction video to an avoidable situation.
46 breaths a minute...the average is 12 - 20...anything above 25 is classed as laboured and cause for concern. And resusing the powder? Pfft, just shows how much SKY value their staffs lives to save a couple of quid. I love how woody says "you swarm em" 🤣 I'd appreciate being swarmed by my dive team if I was struggling, I'd feel taken care of and not alone. Pure teamwork💪🏻
Another great video guys! I loved it. I'm up at 4am nearly in tears with a dislocated knee and you've kept my mind pre occupied❤🤣 take care guys xxx
Get well soon!
@@DIVETALK thankyou! I'll feel so much better after surgery 😊
As an RN , CCRN, for thirty years, you guys present this info great!! Of course, as an ICU RN, I deal with ventilators and these oxygen delivery mechanisms hourly. But you two are great do for non medical viewers!! Love y'all and be careful always!!
these videos make me value breathing fresh air
I never comment on your videos but I just wanted to say I find you both incredibly authentic. You’re a pleasure to “spend time with” 😄
You're the best!
You guys are great, and Gus’ ability to anticipate Woody’s questions and have someone join them on the pod, or have reached out to someone before hand for the answers is excellent. I appreciate the respect and appreciation you guys have for safety procedures and protocol. Awesome video.
Hi Gus and Woody, I did my first Pedi classes last week - I hurt my ears - so at home in bed recovering and loving your channel. Learning heaps - what a brilliant channel. I learnt from you guys to start equalising early and at the beginning of the descent - at shallow depth to prevent ear trauma. Looking forward to learning tonnes over the next three months it will take to heal. Thank you so much for your incredible help.
When in doubt, you must bail out! 💯 Not a bad motto in general, but seems spot-on for rebreather divers. 🙂
Great episode guys! Very interesting and informative, best rebreather seminar ever! 🤓👏 Without Dive talk, I'd have no idea what a KISS rebreather is... instead I can explain how one works, and what mistake to avoid when packing one's scrubbing cannister! AND, I know how KISS rebreathers differ from others. 😁🤘Hope KISS are makin' it rain up in there for you two ambassadors. 💸💰👍
PLEASE more videos with Mike Young!! Would love to learn more about the engineering behind the rebreathers
Holy cow, what a unique fresh and entertaining channel. I'm 31 and have never had an interest in diving. I'm a few videos down the rabbit hole with you as my guide.
I gotta say, well done! I'm a total fan. Just got membership
Quality video as always guys. I know you have mentioned it before but videos like this really bring into focus the importance of not only getting training, but making sure it is the correct training. Maybe a link to the video where you talked about what to look for when finding an instructor would be good or even another focused vid just on researching the correct training you need. I know it may be boring for some but would be hugely beneficial to the ones that need it and you could just put the link to it in your vids and mention it when relevant. Idk maybe that is too much. I was just thinking out loud.
Hel here-so great that you can bring in Mike Young to explain why no sensor yet and Dr Doug Ebersole for explanation of what is happening in C O 2 hit!Access to the horse's mouth,the Masters! Excellent,informative video and please don't think we Brits are weird cheapskates, just a poorly informed instructor passing on bad practice that could kill you! Glad the camerman survived!
I've known individuals that did this, or variations thereon. But I'd never heard of anyone actually teaching it.
A lot of folks will push the duration on a scrubber somewhat, with seemingly far better results. Though it's still a roll of the dice.
About breathing under higher CO2 you can't entirely fight it, but with focus you can adjust to taking deeper somewhat slower breaths. It won't really reduce your gas consumption in the moment, but does seem to help get back to a normal pattern a bit faster.
And yes, you can get CO2 buildup on open circuit just like on the surface when you're exerting. You can go through a lot of gas, and get to breathing so hard you try to breathe more than the reg will deliver. When working hard underwater you need to take more and more frequent breaks to help stay out of that zone.
Areas of "bad air" high CO2 also occur in dry caves and can be dangerous, though in most cases the symptoms are easy to spot. If you want to experience that, there's nothing that says you have to be in the water. Easily accomplished on the couch, and much safer.
I absolutely LOVE you too. Not just for your love of diving but the stewardship you both possess towards this hobby.
20:18 He does have “normal” sized bailout tanks, they say it, but doesn’t get to it. For some reason they aren’t carrying their bailout tanks on them, but must have tied them to a line or something. The thing is, on every rebreather you can bailout to your diluent and use your rebreather on open circuit breathing directly from your diluent without having the gas loop through your scrubber. Usually you’d use this function as a mean of having something to breath while your sorting out your bailout tanks, or if your near the end of your dive, close to the surface and without any more deco to do, as your diluent usually is contained in a very small tank, usually between 2 to 4 litres, and as such is used very fast.
It’s the same principle with the kiss rebreathers Woody and Gus use, but their diluent is contained in a bigger tank.
Not a diver but your videos are soooo interesting. I geek out on science. Plus I’m too terrified to ever dive. I live vicariously through y’all.
"Saving two dollars in the process... Worth it." Lol you guys are great.
Lots of scary things about this video! But lack of judgement due to his impairment really hits hard.
Even if you're the best, highly trained, certified diver with expensive equipment, that mental fog from the CO² hit can cause you to underestimate the danger you are in.
It reminds me a little of Nitrogen narcosis. If you lose your ability to make good decisions at depth, you could easily die.
I've had a co2 hit, which is why I switched to a rebreather with a co2 monitor, as per a previous conversation we had here.
My experience was similiar to what Doug described for around 10 minutes, but on top of that, I felt sick, nauseous and fatigued for well over half an hour. And while those effects aren't fatal like hypercapnia itself can be, they're certainly not good under water either.
@@E_Clampus_Vitusit's because CO2 sensors aren't reliable enough right now for rebreathers. It's in the video where Gus mentioned that question and what Mike Young said about it.
I am a master cave diver with knowledge of every cert.....I also have never touched a body of water in scuba gear. Thank you for the master class dive talk!...
My 2 cents, as a rebreather diver who has experienced a CO2 hit: once you bail out to open circuit your CO2 level is not going to increase, but when breathing VERY shallow rapid breaths you aren't getting rid of the existing CO2 very quickly. It's not a function of being on the loop vs OC, even on the surface it would take a significant amount of time to flush that CO2 out of your system.
Yeh it worries me that diving instructors don't actually know this, I don't dive but I have common sense and my common sense tells me how can U possibly build up more CO2 if there is none in the air Ur breathing.. I'm obviously talking about nitrox or trimix not regular compressed air though (which is what they were talking about because Gus said he asked Doug that)
Also worries me when they said that's another thing we should think about when gas planning because it seems as though I'd want to make sure I had enough bail out gas to make it out alive if I did get a CO2 hit and was breathing 5 litres per minute..
Aloha. Thank for the video. I didn’t read all comments. As a deep diver very important things to do when starting over breathing, 1 exhale more to reduce your co2 level, 2 stop moving making effort ( swimming) because more you move more you create co2. Ask for assistance to do your ascent !
That's crazy, i had no idea how rebreathers worked or that this could happen. That fella is lucky he had his team there!
Sometimes I feel like Gus is a parent and Woody is a kid being like, "But DaD... I want to" lol.
All the time!
it seems like the opposite to me though that is funny
I just watched Monty Hall’s Blue Hole dive I think from like 5-7 yrs ago? In it, they were going to use rebreathers and practiced day before. The cameraman actually had a filter problem so he was breathing in CO2 and he needed help. Luckily they hadn’t gone far down. Then Monty does a test in a lab and they recreate what happened to cameraman. Monty was doing that super fast breathing. It was a good example of what happened. I understand more now what a rebreather is because I don’t dive but it’s nice to know what the equipment looks like that you guys talk about! Nice vid guys!
Hey guys, I had an interesting conversation with my dive instructor about the kids being rescued in that Taiwan cave a few years ago. I would love a video from you guys about what happened there.
It’s coming
There is something so absolutely pure about Woody wondering out loud about an idea and Doug giving him the answer he gets so excited :,)
Best kind of safety training for anything needs to give people a good enough functional understanding of the chemistry, the mechanics, or the physics of what they're dealing with that they can't just invent their own seemingly "smarter" protocols for how to operate the device.
If they had been taught the sorb reaction progresses as a single layer throughout the scrubber they'd have known that mixing it all up was just as bad as poking a straw through it.
So true!I like when I explain things to my GF whilst using physics, engineering, and chemistry. Just had a conversation about dimethyl Mercury vs regular mercury.
Sometimes tweaking it on your own as necessary. Protocol was to mix it back in 2004 in this video. That is how the experts taught people how to do it. These divers anyway and I'm sure they're not the only one. It takes time to figure things out and unfortunately the first people in a new technology or even way of doing things are simply Test Dummies. You have to know what not to do before you know what exactly to do and you learn that through trial and error. Unfortunately rmd through manufacturers doesn't always do a thorough enough job and the consumers are the ones figuring out the details for the producers to tweak. Sometimes when you have a few hundred devices out there being tested doesn't give you the full picture until you have thousands of them out there being used in real-world everyday scenarios
@@OrcinusLaryngologist Mr Ballen fan?
@@berrtusmaximus5212 he has to be,mercury is a random subject to talk about unless you just watched MrBallen recently haha
Great vid! As always, Gus’s face when Woody says something crazy, priceless!
Woody is the real mvp here he's willing to risk it all for research woody ill hold your beer any day my friend
Dive talk THANKS A LOT FOR EXPLAINING THE RE-BREATHER PROCESS!! Anyone could understand the way you guys explained it...keep up the good videos and we'll keep watching!
I have been binge watching these videos for the last week i have no interest in diving but dang i just love watching you guys and learning about all of this but it has definitely reassured me that I'm never getting in the water again lmao i hope you guys always stay safe we need yall here making these video's keep up the great work guys :)
Me too! I’m not a diver and highly doubt I ever will be. But I love Dive Talk!
I’m stuck home on quarantine, I’ve been watching your videos non-stop. I was PADI Open Water certified in 2007 in Curaçao and I was so lucky to have an amazing team of instructors, it was a school trip and they had gone with the same team of people for over 15 years. It was amazing, it was the best thing I’ve done! I was so lucky to have nannied for a family who were going on a trip to get their advanced open water certification and they wanted to include me on their vacation. I am hyped on trying for cave after seeing your passion for it, I was too afraid from misinformation online 😞 - I love your channel! Thank you!
That almost went from a practice body recovery drill, to an actual body recovery drill. He was surrounded by all
The technology and help one could ask for. If he was diving alone, or diving with just one dive buddy, he would probably be dead.
Another good one guys. I think Woody pushing it in a pool with support would be a mega video and give Rebreather divers a real time experience to be aware of
Thumbs up for Woody and Gus! Let’s give them a 100% likes for once- they’ve earned it!
Update: 8 people are jerks lol! (Jk, no one attack me, everyone can have an opinion). Unfortunately for Woody, I don’t think any YT vid has no dislikes. 😕
ikr. I posted a lovely video of my kayaking trip and got a dislike. Why do people do dissss doesn't seem to make sense lol.
@@ChristelVinot Is it important? Do what you enjoy and ignore everything that's not constructive
29:20 If you want to feel a CO2 hit then all you need is high intensity exercise for 20-30 minutes. 20 hard mins on a bike your SAC rate will go crazy, your lungs will be screaming and you'll be gasping for air thinking you might die.
Aaawww So Sweet @24:16 That's What all Divers should Live by Woody.. "Never Dive Alone"
Woody and Gus Australia Here, I Can Not Swim Petrified of Deep Water. Yet I'm watching Your Video's Of Diver's Nearly Dying of Drowning. Listening to your Comments is in one Ear out the Other. There is a Pool in my Backyard it is an in ground pool and I Have Not set Foot in it. I'm ok in the Shower Not a Bath. That is Showing you Both how Calming your Making this all Sound, Even though I don't Understand anything. Sending you Both and Your Families Kindest Thoughts from Australia. 🌏🐨🦘😇
Woody: *asks question*
Gus: "I read your mind, and I have the answer you seek."
This is fascinating stuff that even non-divers like myself can enjoy.
And Woody will be pleased to know that 3 months later, this video still has no downvotes (I can see dislike counts on videos with a browser add-on).
Everytime I watch one of your videos I get more educated and the world of diving which I love so much but I haven't had the opportunity to dive in many years but I still love learning more so your videos are very helpful when I do dive in the future. Thank you for these!
Wow those guys were trained/taught to keep old scrubber and save a few bucks 🤦🏼♂️.
Gus “Just repack it bro”
I knew absolutely nothing about rebreathers before watching this video. Although technical, I still found it very interesting. 👍🏼👍🏼
I go between 4 channels, You guys, Bedtime Stories, That Chapter and MrBallen. You guys are the only channel I watch where I feel that my voice is heard and you guys actually care. Thank you for all you do!
Awe thank you...and of course your voice is heard.
On submarines you can tell if the CO2 is high and you can tell when the just added oxygen
Interesting!
I'm not a diver, don't plan on learning to dive. I am an ex royal navy Submarine veteran so I have an interest in the water in general but I love just putting these videos on and chillin, watching and learning Great!
Guys I love your stuff, I think diving is about the most Rad thing you can do, but God knows I will never do it!! Be safe under there🤙🏼
New diver here from Long Island working on completing open water now...your videos are helping me understand so much more about the diving community and are extremely informative and entertaining! I get more excited to dive every time I watch your videos. Thanks for all you do and for the great content every week 😎
You can experience a CO2 hit without having to risk it in a pool. Just breath into a sealed plastic bag and keep breathing in and out without letting any fresh air into the bag. Within 10 to 15 breaths you will already start to feel the effects. Your body will already start wanting to pull the bag away to get fresh oxygen into your system. And then you realize even after you take the bag away and do breath fresh air, it takes a few minutes for the effects to go away.
Yeah do not try this at home. This is how you die. What if you pass out before you take the bag away and your alone?
@@vashisl33t that's why it's always best to have a partner and they know what's going on and have a plan already in place.
@@vashisl33t You don't put your head in the bag, just seal it around your mouth with your hand, if you pass out you'll break the seal
@@vashisl33t I didn't say put your whole head in the bag, lol. Just put it up to your mouth goofball. You would need to keep breathing like that far FAR past where your instincts are pulling the bag away for you in order to come close to passing out. You won't pass out. And even in the small sliver of a chance you do, your hand falls away from your mouth and your breathing oxygen again. Do you panic everytime someone breathes into a paper bag while having anxiety and tell them they are going to die ? Relax. You can do things safely within reason that doesn't put you into danger.
I guess stuff like this happens cause people just doesnt think through these things, they are just like 'ye doesnt look that bad i can reuse a part of it...' thats just common sense and how most people would think about it. But if you look closley and calculate it you notice that youre saving only 1dollar per dive for risking your life! Imagine being in a cave at this situation...
It shows again how good or even important it is to be mindful and understand evrything arround your gear, and also that you guys talk about these things. So thank you for that and it was very intressting to see how Rebreathers function.
Keep up the great work :)
I'm not a rebreather driver, but I have had asthma since I was very young. One of the things I learned early on was that quick, shallow breathing doesn't get oxygen in your body; and the most important thing to do when having an asthma attack is to breathe as deeply as possible
Goes for many situations in life like if you get a severe panic attack also slow and deep breaths is the key to calm down and help to get the panic attack under control. We can help our body in many ways by just trying to be calm and breath. Now I don't have asthma but I used to work as a paramedic and met many patients with asthma and its really hard to see a person struggle so hard to breath, but I'd like to remind everyone that has asthma to always have their inhalor with them at all times. Even if the inhalor might not help completely sometimes and the patient need stronger medicines and treatment it will help to improve and the person struggling with breathing difficulties and make it a bit easier for them until the ambulance arrives. I hope you are ok!
Best channel on RUclips! Hope you guys smash 1 Million very soon!
Why does it seem the victim is downplaying the entire incident?
It almost appears he is in denial about how bad a situation he was really in
The only water I like diving in, is 2m deep and full of chlorine, but I just cant stop watching these videos! Keep it up guys!
Your bathtub?
So why didn't the two people that were with him when he switched over to his tank immediately take him up? At that point he was surely in trouble. Sounds to me like he doesn't like to take responsibility for screwing up. So it didn't get him this time, but if he doesn't rethink his training; it will.
You would think they noticed him switch over. So they should have a policy to then immediately start a rescue and safe surfacing.
I know nothing about scuba diving but these guys are awesome and so entertaining to watch
15:05 perfect moment for Gus's traditional comment about 🍌
I can see by your facial expressions you were thinking this too, but this guy has a huge ego. Refuses to admit he was not in control after the co2 hit.
I'm not convinced it's his ego talking. My understanding is since he confesses confusion, and probably guesses that he's hit, he then tells the story of how that hit did not allow him to think straight, therefore keep believing that he is in control of the situation even though he clearly isn't. And he says that probably to emphasise how grave the situation really was for him. That's my opinion
Danke!
Oh wow...thank you for this!
"there is no way of inflating Kevin's BCD" what about oral inflation? This is really a question. I can do it with my gear
If the other divers are still on the loop of the ccr it’s hard to do an oral inflation. So they need to get of the loop first, go in to OC or BO mode and then inflate the buddies bcd. Experienced divers will maybe able to manage that without going OC but this is beyond my level
We learned so much from this video. No trying hypercapnia Woody!!! That animation video really helped me understand sort of how the rebreathers work and so glad you guys have such amazing friends to be able to ask questions and share that knowledge with us. Before long you guys will be running your own scuba school!!! Thanks as always for another great video you guys!!
Great to hear!
Pretty scary how the diver is so adamant he was in control even after all the facts and expert opinions are clear. Almost seems prideful or egotistical, cant say i made a mistake (reusing scrubber), and didn't have proper equipment (proper size bailout tank). One thing your channel and Mr. Ballens have tought me: ego and diving doesn't mix to well 😆
he is constructively criticizing himself while showing how being impared from co2 can put you in a dream like state
15:47 this segment is what i was mainly pointing at about "ego". He still seems convinced it was a controlled ascent. Being in a haze from C02 and running out of your own air, relying on two different divers air (he even rejected a good air source from panic) doesn't seem so controlled. I dont even blame him for the accident, this video made it clear that there was a problem with the teaching/culture of diving at this time and region (the shocking number of divers that thought reusing sorb was a viable option). Point is: Just seemed like he was downplaying it (saying he was in control), which i attributed to ego. Just my worthless non diver opinion tho 😆
@@GapingClam he didnt say he was in control. go watch it again he remembers it being a totally normal ascent. he was so fogged out what he remembers is it going well and the ascent was fine only realizing after because of the video
@@dominicklittle9828 umm i gave u a time stamp... He says "i do believe, and i still believe now, that we did it in a controlled manner"
Edited to get quote right
@@PaulAnthonyDuttonUk how is it just emphasis? He literally states that even now believes he was in control, even though the experts disagree... Thats not emphasis thats him clearly saying he disagrees with the experts
Thumbs up for getting opinions and references from the specialists when needed.
woody i think you missed the part where they said they were taught incorrectly. they not saying this is how it should be done. they are admitting its wrong. love how passionate woody gets, he just wants to share his knowledge and teach. i highly doubt they did this to save money they were just taught wrong. i can finally relate aswell to the body as a good co2 sensor aand trusting yourself. I used to load lorries via overhead crane and we had these dodgy barriers that were to go up to the lorry on the sides so if we fell the barrier would save us...however like the co2 sensor they were unreliable and would move, i told health and safety i rather no barrier forcing me to be cautious than a false sense of security of a barrier knowing if i did fall my weight would push the barrier and id end up between the barrier and lorry.
I don’t know much about rebreathers, but I assume that you have some instrument that will indicate when you have a problem with your oxygen, right? Now my next question is, if you have an issue with your oxygen, does it mean by default that your CO2 levels will go up?
If the answer to this 2 questions is YES, then per my logic (which might be filled with missing information), then you don’t need a CO2 indicator.
Your oxygen indicator will alarm you of a problem with oxygen, by default you CO2 levels should rise (plus your own “body” indicator) and you’ll switch to your bail out.
I would love to know if my logic is correct, and if not, to learn more about why.
Your channel is very entertaining for me to watch, thanks!
And by the way, I give you a 100% thumbs up 👍. At least so far on all the videos I watched.
Im glad I found this Chanel! Not looking to dive but after watching Mr. Ballens videos I found yall and its so cool and informative to find out how it is seen from the eyes of veteran divers
