hey, my grandpa frank was the first human subject for these experiments (and got pneumonia, as you mentioned). i can ask my dad if anyone has questions, but sadly it’ll all be second hand as grandpa frank passed on years ago. i believe it was actually a talk he gave that inspired cameron to include the fluid breathing scenes in his stories.

As someone who does research in microbiology/immunology I am very worried about this technique. Altough many points I initially thought of at the beginning of the video (the difficulty/weight related to breathing the liquid, adding a scrubber for co2) were added later I still have lots of concerns pneumonia being the main concern. Our lungs are covered with a thin layer of protective mucus that helps trap and expel pathogens. Having a liquid in the lungs disolve and remove this barrier brings lots of concern. What happens to the epithelial cells long-term? I would believe irritation and inflammation would come in fast. Normal bacteria that are usually harmless would have the opportunity to have an easy point of entry during the long time of the dive and then cause infection. Another point to think of, breathing and swallowing are done via the same tube. Who's to say you won't swallow that liquid? Obviously it was thought of and it should be safe to swallow. However, what happens if you have gastric fluids that leak up? This is not something that happens when you are filled with air and standing upright but in a neutral buoyancy situation and filled with water? I cant imagine the problems of having gastric acids mix in everything. Also, as gus pointed out, other air cavities add more complexity to the development of this technology. How will you even see? All in all, there is a lot to think about and tesf before this ever becomes a thing.
human body is clearly not designed to do that, not even to go deep in water, thats probably why sat dive is one of the most dangerous job ! we could get a graft of gill that these issue wouldnt be resolved, i know i watch waterworld to much :D
@@vallsz To your credit, there IS a deer(?) in China that has GILLS... Should someone study them before the little thing is sent into extinction, there's at least some chance that via crspr or some similar gene-splicing and artificial bio-tech, we could "tailor make" tissues for gills and have a plastic surgeon alongside a cardio-pulmonary specialist work out how (exactly) to "install" them...

To be fair, it is possible to develop a liquid that doesn't dissolve the mucus layer. Mucus in of itself is a very good substance when it comes to resisting reactions. But yeah, we would be better off trying to create unlimited rebreathers that separate oxygen from hydrogen in the surrounding water or trying to create temporary gills for divers. But everything essentially has their golden hurdles to overcome.

@@JustSomeDinosaurPerson "Unlimited Rebreather" : You don't get around the fact that the more you compress a gas, the more issues it will cause. Non-reactive parts of the mix will dissolve into your tissues (and thus require lengthy decompression stops) and the reactive parts (O2 primarily for breathing gases) have to be very carefully adjusted so they don't become toxic. Also as the breathing gas compresses a lot of the same issues as breathing liquids start happening, such as reduced CO2 expulsion and increased breathing effort. Our lungs simply didn't evolve to move and process dense substances..
I imagine coming out of the liquid would be the hardest part. Lungs have a huge surface area that they get that by basically being huge cave systems for air to travel down. Now imagine you flood them and then allow them to drain. You are gonna have a ton of areas that are basically blocked like a P-Trap preventing air flow. Which is good in your sink to stop sewer gasses coming out, but not so good when you need oxygen to live.
I don't think that's going to be such a problem, as you're going down the pressure is going to increase which would decrease the physical size of bubble. As well as the bubble shrinking the body will slowly absorb the gas. My $0.02 for the problem that you've stated is that it will need to be factored into any decompression that needs to happen as the diver returns to the surface
They're starting to seem annoyed with each other. And honestly Gus is getting a little annoying but woody getting so visibly annoyed makes it all the more un enjoyable to watch
Personally I think we will get very advanced drones and pressurized suits far before this happens. So demand for this will probably just diminish more and more. Overall, liquid breathing is riddled with problems, that even if you actually somehow solve them, it's going to be *very* uncomfortable.
I know I’m replying to a 2 year old comment. But I’m sure you are right we will get alternative technologies before liquid breathing… just don’t underestimate the human drive to go somewhere themselves. Like sure. We could invent drones that go to Mt. Everest or the bottom of the sea, that won’t stop people from going in person 😅
2:48 - In fact, the trials of "Francis J. Falejczyk" were followed closely by James Cameron and would ultimately be the inspiration for the Liquid Breathing Suit, in "The Abyss". Therefore, Woody's comparisons aren't necessarily unfounded.
Abyss is one of my favourite films. So glad you guys talked about liquid diving because I have always wondered (but not got around to researching myself) if it really is a thing. Love you guys keep up the amazing work.
I only ever dived once in open shallow water as an introduction while on vacation. The first thing I thought of on this topic was what Gus said about clearing your mask if it's flooded, I also saw the mice and rats experiment some years ago. Great content as usual guys. Thanks. Greetings from Ireland to the hosts and subs.
As someone who has had 3 angiograms and has 5 stents in coronary arteries, you don't want to have a catheter up your femoral artery. During an angiogram, you have to lay flat and still. Afterwards, they put this strap device around your pelvis and butt that applies precise pressure to the incision site and you have to lay flat for 6 freaking hours. No sitting up as they don't want you to activate your abs.
@@mikedineen7857 yep. Depending on the patient they can go through the radial. There’s actually a similar band called a TR band that’s used for pressure on the radial artery.
This has probably been said by someone already, but I’m on Woody’s side with this. I can definitely see this happening, plus I know that I’d be willing to take the risk to try this out eventually once science and technology advances enough to either manually drain your lungs of liquid or to beat pneumonia with a very high chance of survival and full recovery. Also, as a side note, your channel is truly amazing. I found it just a few weeks ago and have been watching it all the time and it’s been a blessing for me. Your channel has helped to renew my love of diving and of the water in general, as well as helped me to get myself out of a rough patch of my life where I wasn’t in the best place mentally, so I thank you both, Woody and Gus. You two are truly amazing and are extremely educational. One more side note, don’t ever worry about scaring people away from diving, for some that get scared away, maybe it’s better they don’t try diving because I could see them being more prone to panicking since they are already at least somewhat nervous about diving, if not just the water in general. Thank you both again for being such amazing and knowledgeable divers, as well as great entertainers at the same time.
I don’t think people understand how painful it would be to have liquid in your lungs. It would trigger your coughing response and you’d vomit, your lungs hate having anything other than air in your lungs.
A much more realistic solution to replace the need for breathing world be some sort of miniaturized coronary bypass machine. They are used in surgeries for people with heart surgeries. They pump the blood throughout the body but also oxygenate it and remove carbon dioxide. Maybe in the future we could find a way to take just the blood oxygenator and carbon dioxide remover portion of the bypass machine (since you wouldn’t need to also pump the blood as the heart is still actively breathing) and miniaturize it enough to be worn. Then you would have to suspend lung activity and empty them of air so it can’t be compressed (or some other solution to them being filled with air as like you guys mentioned there are other areas of the body that have pockets of air that would need some sort of solution. Obviously we are far off from a tech like this but at the rate technology is improve and being miniaturized I think it’s definitely possible to create the machine. It seems more likely that creating a viable method of making out lungs act as a set of gills.
First of all, I want you guys to know I am a non-diver who has been watching your videos for awhile; and even though I have always had a fear of scuba diving (my dad was a former scuba diver who described an accident he witnessed to me when I was about 5) your videos have literally led me to sign up for an open water scuba class! Second, I just wanted to say that liquid breathing comes in two forms... partial liquid breathing and total liquid ventilation. For the purposes of diving you would require full liquid ventilation, which is absolutely possible (and already done in the case of some premature babies). The problem for full liquid ventilation for adults is that, in the context of diving, the CO2 exchange between the lungs and the liquid just is not good enough. In other words, divers would end up dying from C02 build up. One solution, which has been patented, but not actually built or tested, is a manual CO2 scrubber that would scrub the C02 from your blood. As you can guess this would require a diver to have a C02 scrubber attached directly to one of the major veins in your body... And yes, overcoming the the mammalian instinct to not inhale liquid is a big deal as is removing the liquid after the 'dive.' It seems to me that taken together these things would seriously limit who would be willing and capable of using a liquid breathing dive system. It would probably limit liquid diving to the purview of the military or serious professional divers... But yeah, you guys know all of this because its in this video! :D
Hi Gus as and hi Woody a big hello from Michael Edinburgh,I came across a video of yours about 7 months ago and your warm at humerus presentation draws you in keep your excellent work subs are rising very nearly 200kyou deserve all good fortune and long have an ever growing subscriber count Best wishes and love to you and your family Michael

Woody's cup-of-joe, $4.95...Woody's hat, $19.99...Gus' reaction to Woody saying "I know aliens have been here...I can't scientifically prove that, yet"...🙄🤦...😂🤣🤣...Priceless
I meeeeeeean, it's still likely to have the natural instinct to get out of the water. It thinks it's drowning but that's a lot different from actually drowning.
Love watching you guys and catch myself binging on many of the guests you guys feature. Still can’t wrap my head around that panic right before drowning you’d feel when breathing liquid. How much confidence would you have in that synthetic liquid in that moment?!
Realistically, even if this was possible, would it actually become a widespread thing or would it be some very niche form of diving? I’d suspect that standard compressed air/rebreather diving would probably still remain the normal option, especially as many divers don’t want to and likely don’t actually need to go down past recreational or today’s technical dive depth limits.
@@stevenr6397 my understanding is that for some places, even saturation diving is being phased out in favour of using RVs or similar, because as long as humans are involved there is always that element of risk.
I had to pause it at 41seconds I’m already dying. Gus (every time we talk about science you have the wildest theories ….and people get behind them..)🤣🤣🤣 (Woody first of all I don’t think that’s fair to say to me …)🤣🤣🤣🤣
13:21 ask people who have been conscious on ventilators. It’s a horrific and painful experience. It’s isn’t at the same rate at which by body is directing your diaphragm to work… meaning your natural reflex is constantly fighting it. Apparently it’s extremely painful and you’re in constant discomfort. This is with the pressure from the ventilator. Now imagine that same pain and issue from fighting your natural breathing to the pain from crushing your rib cage to move the liquid. I imagine unless they can overcome that pain and constant discomfort, even a viable safe solution would still find little to no one willing to do it even for massive paychecks.
Ok if it has been mentioned before sorry I am not reading all comments #1 over coming the startup. Do the infusion process under sedation. #2 over come the problem of respiration pressure of the Flouro fluid. Don't use the diver to circulate the fluid, Use pumps like a ventilator. #3 Use a tracheotomy tube and not flood the helmet with the breading fluid but a fluid that is easier to see though with special contact lenses. #4 after the dive. Again put the diver under sedation and invert them. Allow gravity to help transition from fluid to gas. This way the diver doesnt have to suffer the transition and the most amount of fluid can be removed.
The 701m deep dive was actually done in a pressurised tank, the deepest saturation divers have worked in the open ocean is 530m. Both dives were a part of the Comex Hydra I - X dives in the 1980s.
I actually met a person who participated in experiment in San Diego in 80-s. He had one lung filled with PFC and felt well. No pnemonia either, but some cough few weeks afterwards. The method probably can be improved with better purification of PFC, minimizing medical risks.
Dropping a drone into Devils hole would work, the tripods emergency services use over holes (Ghostbusters II style) and lower some kind of sonar mapping device first, those things can pick up detail a long way, if it measured water speed and direction you would know if a drone could be strong enough to navigate autonomously, the water speed would drop off if the way opens up until it reached another smaller exit.
Ideas: 1. What about PFC and Saline H2O + NaCl solution? That partially helps alleviate the density problem. Add just enough PFC to dissolve the needed CO2 and let the saline be the carrier for O2. 2. Artificial gills - this is actually a great idea. Our blood vessels can be tapped or augmented (for instance when doing heart-lung bypass or a central line) and some form of CO2 exchanging media that interacts with sea water could be created. And speaking of bypass 3. Put divers on lung-bypass. Simply create a pack-worn bypass unit that oxegenates and scrubs the blood and the diver actually WONT NEED TO BREATHE AT ALL. It will be like holding your breath and not running out of air. Imagine holding your breath and NOT feeling the urge to inhale after 30 seconds... I actually think this is probably the best bet. Bypass the need to breathe entirely by having a machine exchange blood gasses for you.
David Blaine once tried to breath liquid oxygen for one his breath hold attempts but ultimately failed due to the pressure it would generate on the lungs. It would be like an elephant standing on your chest while trying to breathe.
You mentioned Ben McDaniel. I was at Vortex diving the day(s) they were looking for him 12 years ago.. We spoke to the crew and the ROV was talked about.. There was a mention of only using it at the point where no divers would risk going.. they said they found his staged tanks, and there was some scratch marks on some rocks near a sandy bottom, but there was no way anyone could have fit in the tiny opening unless he dug the sand out somehow.
You guys make cave diving look AWESOME! I am not a diver at all! I’m a Buddhist teacher, but i can only imagine the peace one finds in the water. We use many things to train our minds to focus..i’ve learned that in times of life and death our focus can become super Human! 🙏🏻 be well..
There are certain pressures where cellular biochemistry changes, so even with liquid breathing, there will still be depths beyond normal human reach, but... They're pretty damn deep. Now.... There is. A potential alternative to oxygenating people without the lungs. It can be done to a degree through gut tissue (I'm talking up the rear, it was explored because it's actually how some turtles suppliment their oxygen levels during underwater brumation), but that doesn't really fix the gas pocket issue. I just wanted to let yall know that there may be even less glamorous tech in the future lol
On 10 May 2014, Nereus ROV was lost while exploring the Kermadec Trench at a depth of 9,900 meters (32,500 ft). Communications were cut off at around 2 p.m. local time, and debris retrieved later revealed that it imploded due to high pressure. Or so says Wiki. That is crazy deep.
i think its something like 30% of drowning victims have no water in their lungs because of a bodily reaction to shut the throat as soon as water hits the back on an inhale, so some people might be unable to breathe liquid oxygen because their body wont let them
There is a way to eliminate the limitations that breathing air at depth imposes on the body. It’s called heliox diving. You breathe mostly helium air with a couple of percent oxygen. It’s what saturation divers breath. My diving instructor Jerry Clourser at marine diving technologies in Santa barbers told me a story about navy experimental divers, which Jerry was, breathing liquid o2. The divers that did this almost always got pneumonia. Jerry said that liquid o2 was used to treat people that had inhaled particles in there lungs to flush the particles out. Like someone who was in a dune buggie wreck and inhaled a bunch of sand. They still might catch pneumonia but it’s better than a lung full of sand.
Gus, you are correct that this is not a technology that will be adopted by recreational diving, but don’t forget that there are many commercial and military divers willing to take these extreme risks. It’s great to see technology developed for diving moving to the medical field to help so many people.
I literally just watched this video the other day and was hoping you’d give your perspectives. Pretty interesting stuff, I can’t imagine how it would feel breathing liquid tho, it must go against all of your bodies natural instincts and must be horrible. But it would solve so many diving issues if it was possible!
I've been scuba diving since 1976 and probably half the diving I did in my life was Cave Diving concerning fluid breathing systems I think it's going to be completely possible I'm a respiratory care practitioner and I think if they set up a type of ventilator that detects when you're taking a breath in a pump is activated and assists in pushing the fluid into your lungs and the same when you exhale when it comes to initially starting the system I think they would put the person out with propofol so they're not conscious when they're drowning and then immediately take them off and start the dive
If they had an enclosed helmet they would need to leave some space at the top and some sort of surface agitator to break surface tension and make the exchange of CO/2 much easier. Kind of like an air stone in an aquarium. The air bubbles are not oxygenating the water, they are breaking surface tension and allowing CO/2 to escape from the water.
Just thinking about it, like Woody said, there'd be a better method of transitioning from the air to liquid breathing, simple drowning just isn't on the menu, but, the physiological reactions and triggers for the drowning response CAN be modified. The coughing reflex is triggered by receptors in the trachea so they could be anesthetized pretty much like they do when intubating a patient and whole mental aversion to the idea can be dulled with some nice minor tranquilizers, some Xanax with your lidocaine sir ? oh yes please !
Just konk my ass out and let me wake up in the g** d*** thing... I'll handle it all then when I HAVE to. Making me try to sit through it willingly... um... no. ;o)

I imagine coming out of the liquid would be the hardest part. Lungs have a huge surface area that they get that by basically being huge cave systems for air to travel down. Now imagine you flood them and then allow them to drain. You are gonna have a ton of areas that are basically blocked like a P-Trap preventing air flow. Which is good in your sink to stop sewer gasses coming out, but not so good when you need oxygen to live.
I don't think that's going to be such a problem, as you're going down the pressure is going to increase which would decrease the physical size of bubble. As well as the bubble shrinking the body will slowly absorb the gas.
My $0.02 for the problem that you've stated is that it will need to be factored into any decompression that needs to happen as the diver returns to the surface
I just want you guys to know your chemistry as friends is what makes this channel so amazing!
Yeah all you need is a rib cage crusher device and a underwater portable dialysis machine. Sign me up!
Gus answering her questions, priceless...Woody always thinking ahead and game for anything. You're the perfect team,
They're starting to seem annoyed with each other. And honestly Gus is getting a little annoying but woody getting so visibly annoyed makes it all the more un enjoyable to watch
@@skytho5799 Oh no I don't think they are. I think they're joking around.
Personally I think we will get very advanced drones and pressurized suits far before this happens. So demand for this will probably just diminish more and more. Overall, liquid breathing is riddled with problems, that even if you actually somehow solve them, it's going to be *very* uncomfortable.
true
in theory they could make it from superfluid... virtualy 0 resistence
I know I’m replying to a 2 year old comment.
But I’m sure you are right we will get alternative technologies before liquid breathing… just don’t underestimate the human drive to go somewhere themselves.
Like sure. We could invent drones that go to Mt. Everest or the bottom of the sea, that won’t stop people from going in person 😅
2:48 - In fact, the trials of "Francis J. Falejczyk" were followed closely by James Cameron and would ultimately be the inspiration for the Liquid Breathing Suit, in "The Abyss". Therefore, Woody's comparisons aren't necessarily unfounded.
It took 3 minutes for woody to mention aliens.. I'm surprised it took so long that's out of character for him
Someone check him for the bends 😂
I believe that Ed Harris's character wore special eye contacts which allowed him to see through the liquid.
Dangit guys! You always post right before I work and I struggle with saving it for after or starting my day with it. Keep up the content!
Abyss is one of my favourite films. So glad you guys talked about liquid diving because I have always wondered (but not got around to researching myself) if it really is a thing.
Love you guys keep up the amazing work.
The pre-video smackdown between you two was epic!!♥️🤣🤣
“Join the Navy, they said”. I’m cracking up!!!
I haven't looked forward to Mondays in years, between you and the Divers ready channel, I get excited.
The Abyss is one of the best science fiction movies ever made! And it's about diving! ;)
I only ever dived once in open shallow water as an introduction while on vacation. The first thing I thought of on this topic was what Gus said about clearing your mask if it's flooded, I also saw the mice and rats experiment some years ago.
Great content as usual guys.
Thanks.
Greetings from Ireland to the hosts and subs.
Congrats on 200K guys!! Been a fan of your channel for awhile, since your first MrBallen react vid.
As someone who has had 3 angiograms and has 5 stents in coronary arteries, you don't want to have a catheter up your femoral artery. During an angiogram, you have to lay flat and still. Afterwards, they put this strap device around your pelvis and butt that applies precise pressure to the incision site and you have to lay flat for 6 freaking hours. No sitting up as they don't want you to activate your abs.
Ah, the good old fem-stop device.
I actually think it's a error in the original video. The catheter can/should be venous for this.
They go up your arm now.
@@mikedineen7857 yep. Depending on the patient they can go through the radial. There’s actually a similar band called a TR band that’s used for pressure on the radial artery.
I retired after 43 years of nursing.
@@mikedineen7857 I've had it both ways. The reconned thru my radial and placed stents through the femoral.
I love coming back from work to a video of dive talk!
The Ben McDaniel story is insane. Can't wait til you guys cover it!
Gus your face when Woody started talking about aliens made me cackle like a fool lol
Gongrats on 200k you deserve it. Love you guys
This has probably been said by someone already, but I’m on Woody’s side with this. I can definitely see this happening, plus I know that I’d be willing to take the risk to try this out eventually once science and technology advances enough to either manually drain your lungs of liquid or to beat pneumonia with a very high chance of survival and full recovery.
Also, as a side note, your channel is truly amazing. I found it just a few weeks ago and have been watching it all the time and it’s been a blessing for me. Your channel has helped to renew my love of diving and of the water in general, as well as helped me to get myself out of a rough patch of my life where I wasn’t in the best place mentally, so I thank you both, Woody and Gus. You two are truly amazing and are extremely educational.
One more side note, don’t ever worry about scaring people away from diving, for some that get scared away, maybe it’s better they don’t try diving because I could see them being more prone to panicking since they are already at least somewhat nervous about diving, if not just the water in general.
Thank you both again for being such amazing and knowledgeable divers, as well as great entertainers at the same time.
I don’t think people understand how painful it would be to have liquid in your lungs. It would trigger your coughing response and you’d vomit, your lungs hate having anything other than air in your lungs.
A much more realistic solution to replace the need for breathing world be some sort of miniaturized coronary bypass machine. They are used in surgeries for people with heart surgeries. They pump the blood throughout the body but also oxygenate it and remove carbon dioxide. Maybe in the future we could find a way to take just the blood oxygenator and carbon dioxide remover portion of the bypass machine (since you wouldn’t need to also pump the blood as the heart is still actively breathing) and miniaturize it enough to be worn.
Then you would have to suspend lung activity and empty them of air so it can’t be compressed (or some other solution to them being filled with air as like you guys mentioned there are other areas of the body that have pockets of air that would need some sort of solution.
Obviously we are far off from a tech like this but at the rate technology is improve and being miniaturized I think it’s definitely possible to create the machine. It seems more likely that creating a viable method of making out lungs act as a set of gills.
"I cant prove that scientifically.... Yet" Favorite line hahaha
First of all, I want you guys to know I am a non-diver who has been watching your videos for awhile; and even though I have always had a fear of scuba diving (my dad was a former scuba diver who described an accident he witnessed to me when I was about 5) your videos have literally led me to sign up for an open water scuba class!
Second, I just wanted to say that liquid breathing comes in two forms... partial liquid breathing and total liquid ventilation. For the purposes of diving you would require full liquid ventilation, which is absolutely possible (and already done in the case of some premature babies). The problem for full liquid ventilation for adults is that, in the context of diving, the CO2 exchange between the lungs and the liquid just is not good enough.
In other words, divers would end up dying from C02 build up. One solution, which has been patented, but not actually built or tested, is a manual CO2 scrubber that would scrub the C02 from your blood. As you can guess this would require a diver to have a C02 scrubber attached directly to one of the major veins in your body...
And yes, overcoming the the mammalian instinct to not inhale liquid is a big deal as is removing the liquid after the 'dive.'
It seems to me that taken together these things would seriously limit who would be willing and capable of using a liquid breathing dive system. It would probably limit liquid diving to the purview of the military or serious professional divers...
But yeah, you guys know all of this because its in this video! :D
Starting the day with a Dive Talk video ? Yes please ! Also, congrats on the 200k subs!
Congrats on the 200k subs. I'm no diver but this channel a gem
4:15 "Will you just back it up and not talk?"
Passive aggressive Woody moments are the best.
Ive been waiting on this video for a long time! Cool to see you guys get to it!
Hi Gus as and hi Woody a big hello from Michael Edinburgh,I came across a video of yours about 7 months ago and your warm at humerus presentation draws you in keep your excellent work subs are rising very nearly
200kyou deserve all good fortune and long have an ever growing subscriber count Best wishes and love to you and your family Michael
Also the knowledge and info on safe practice is ultra important to anybody enagening in this potentially dangerous work will help most people to engage in safe practice lol be Michael Edinburgh
Gahahaha when he brings up the Abyss I was like, Whoa, slow down, and let everyone else catch up with you. lmao.
Bud had special contacts in. The whole scene showed him putting them in so he could focus thru the liquid
Love it when you guys do diving science and technology videos! This one was particularly interesting. More, please ... :)
Woody's cup-of-joe, $4.95...Woody's hat, $19.99...Gus' reaction to Woody saying "I know aliens have been here...I can't scientifically prove that, yet"...🙄🤦...😂🤣🤣...Priceless
"yes the rat is breathing water" as it shows a rat acting identically to a rat which isn't underwater but at deaths door.
Exactly, poor thing was gasping. That broke my heart.
I meeeeeeean, it's still likely to have the natural instinct to get out of the water. It thinks it's drowning but that's a lot different from actually drowning.
Love watching you guys and catch myself binging on many of the guests you guys feature. Still can’t wrap my head around that panic right before drowning you’d feel when breathing liquid. How much confidence would you have in that synthetic liquid in that moment?!
the video they reviewed nailed the science of diving. probably the best I've seen them review
Realistically, even if this was possible, would it actually become a widespread thing or would it be some very niche form of diving? I’d suspect that standard compressed air/rebreather diving would probably still remain the normal option, especially as many divers don’t want to and likely don’t actually need to go down past recreational or today’s technical dive depth limits.
I think breathing liquid would be safer in the aspect of pressure but as for other aspects or whether it is even possible, I don’t know
deffinately one to put used as the next notch up from saturation diving - only for specific extreme reasons
It could let space travel be easier too
@@stevenr6397 my understanding is that for some places, even saturation diving is being phased out in favour of using RVs or similar, because as long as humans are involved there is always that element of risk.
I saw aliens doing snorkeling, my glasses got flooded and I saw them
“I cannot prove that scientifically, YET” 😂😂. Please put this on some merch.
I had to pause it at 41seconds I’m already dying. Gus (every time we talk about science you have the wildest theories ….and people get behind them..)🤣🤣🤣
(Woody first of all I don’t think that’s fair to say to me …)🤣🤣🤣🤣
Hahaha! Gus, your face was perfect once you heard the subject of the video and realized that's just what Woody said lol. That was awesome...
😁
13:21 ask people who have been conscious on ventilators. It’s a horrific and painful experience. It’s isn’t at the same rate at which by body is directing your diaphragm to work… meaning your natural reflex is constantly fighting it. Apparently it’s extremely painful and you’re in constant discomfort. This is with the pressure from the ventilator.
Now imagine that same pain and issue from fighting your natural breathing to the pain from crushing your rib cage to move the liquid.
I imagine unless they can overcome that pain and constant discomfort, even a viable safe solution would still find little to no one willing to do it even for massive paychecks.
You guys are awesome, I was so curious about this!
We just need that little breathable mouthpiece qui gon and obiwan used to dive with jar jar.
Compliments to Gus and woody for teaching us a thing or two from Alma and Glen from Australia
Love the banter between Gus and Woody.
"maybe even the Mariana trench"
Gus: [epic eye roll]
🤣
Ok if it has been mentioned before sorry I am not reading all comments
#1 over coming the startup. Do the infusion process under sedation.
#2 over come the problem of respiration pressure of the Flouro fluid.
Don't use the diver to circulate the fluid, Use pumps like a ventilator.
#3 Use a tracheotomy tube and not flood the helmet with the breading fluid but a fluid that is easier to see though
with special contact lenses.
#4 after the dive. Again put the diver under sedation and invert them.
Allow gravity to help transition from fluid to gas.
This way the diver doesnt have to suffer the transition and the most amount of fluid can be removed.
Woody is correct. End of statement. I'll be your first pink squid-hat-wearing disciple. You can be our conduit to THEM. HAHAHAHAHAHAHAHAHA
Love you dudes! Have a reply for your hard work.
Woody: the Aliens in the Abyss! Gus: blank, dead stare. Snort. Y’all are the literal best. 🤣
The 701m deep dive was actually done in a pressurised tank, the deepest saturation divers have worked in the open ocean is 530m. Both dives were a part of the Comex Hydra I - X dives in the 1980s.
Great episode!! Loved the Abyss!! You guy's rock.. ♥️
That dude who completed this experiment by being submerged in oxygenated liquid has nads the size of an m1 abrams tank.
Congratulations on 200k subs 🤗🎉🎈✨ keep up the grind much love ta ya guys stay safe
I actually met a person who participated in experiment in San Diego in 80-s. He had one lung filled with PFC and felt well. No pnemonia either, but some cough few weeks afterwards. The method probably can be improved with better purification of PFC, minimizing medical risks.
"You can't see through liquid!" Lol. Funniest thing I've heard in a while.
Dropping a drone into Devils hole would work, the tripods emergency services use over holes (Ghostbusters II style) and lower some kind of sonar mapping device first, those things can pick up detail a long way, if it measured water speed and direction you would know if a drone could be strong enough to navigate autonomously, the water speed would drop off if the way opens up until it reached another smaller exit.
Ideas:
1. What about PFC and Saline H2O + NaCl solution? That partially helps alleviate the density problem. Add just enough PFC to dissolve the needed CO2 and let the saline be the carrier for O2.
2. Artificial gills - this is actually a great idea. Our blood vessels can be tapped or augmented (for instance when doing heart-lung bypass or a central line) and some form of CO2 exchanging media that interacts with sea water could be created. And speaking of bypass
3. Put divers on lung-bypass. Simply create a pack-worn bypass unit that oxegenates and scrubs the blood and the diver actually WONT NEED TO BREATHE AT ALL. It will be like holding your breath and not running out of air. Imagine holding your breath and NOT feeling the urge to inhale after 30 seconds... I actually think this is probably the best bet. Bypass the need to breathe entirely by having a machine exchange blood gasses for you.
David Blaine once tried to breath liquid oxygen for one his breath hold attempts but ultimately failed due to the pressure it would generate on the lungs. It would be like an elephant standing on your chest while trying to breathe.
You mentioned Ben McDaniel. I was at Vortex diving the day(s) they were looking for him 12 years ago.. We spoke to the crew and the ROV was talked about.. There was a mention of only using it at the point where no divers would risk going.. they said they found his staged tanks, and there was some scratch marks on some rocks near a sandy bottom, but there was no way anyone could have fit in the tiny opening unless he dug the sand out somehow.
LMFAO… Woody; “the abyss,” Gus just rubs his face. Gus; “ok,alright!” Lolol you guys rock!
You guys make cave diving look AWESOME! I am not a diver at all! I’m a Buddhist teacher, but i can only imagine the peace one finds in the water. We use many things to train our minds to focus..i’ve learned that in times of life and death our focus can become super Human! 🙏🏻 be well..
Lol, when the abyss came up... The reaction... The facepalm...lol
There are certain pressures where cellular biochemistry changes, so even with liquid breathing, there will still be depths beyond normal human reach, but... They're pretty damn deep.
Now.... There is. A potential alternative to oxygenating people without the lungs. It can be done to a degree through gut tissue (I'm talking up the rear, it was explored because it's actually how some turtles suppliment their oxygen levels during underwater brumation), but that doesn't really fix the gas pocket issue. I just wanted to let yall know that there may be even less glamorous tech in the future lol
😂 Gus face was so awesome
I’m sure Woody would try it when tested safe 😅
it's supposed to be educational... but I'm here for Gus' funny reactions 😂
On 10 May 2014, Nereus ROV was lost while exploring the Kermadec Trench at a depth of 9,900 meters (32,500 ft). Communications were cut off at around 2 p.m. local time, and debris retrieved later revealed that it imploded due to high pressure. Or so says Wiki. That is crazy deep.
Thank you for sharing this! The video was AMAZING! I love the science explained.
I'm concerned that Gus will obtain an injury by the sheer number of eye rolls in this video. Also: the minimum wage comment ☠️🤣🤣🤣
🤣🤣🤣
🍻🤣😂
i think its something like 30% of drowning victims have no water in their lungs because of a bodily reaction to shut the throat as soon as water hits the back on an inhale, so some people might be unable to breathe liquid oxygen because their body wont let them
Nobody's breathing LOX and living to tell the tale lol.
@@jwm6314 i didnt mean actual LOX i meant oxygenated liquid
I love when woody goes on his alien tangents lol it’s so funny
7:00 - The exact moment when the guy on the right realizes that N2 makes up 4/5 of the air.
There is a way to eliminate the limitations that breathing air at depth imposes on the body. It’s called heliox diving. You breathe mostly helium air with a couple of percent oxygen. It’s what saturation divers breath. My diving instructor Jerry Clourser at marine diving technologies in Santa barbers told me a story about navy experimental divers, which Jerry was, breathing liquid o2. The divers that did this almost always got pneumonia. Jerry said that liquid o2 was used to treat people that had inhaled particles in there lungs to flush the particles out. Like someone who was in a dune buggie wreck and inhaled a bunch of sand. They still might catch pneumonia but it’s better than a lung full of sand.
I asked in a livestream If you guys would react to liquid breathing and Gus said “NO” 😹
Can’t be giving away all our secrets
Gus, you are correct that this is not a technology that will be adopted by recreational diving, but don’t forget that there are many commercial and military divers willing to take these extreme risks. It’s great to see technology developed for diving moving to the medical field to help so many people.
I literally just watched this video the other day and was hoping you’d give your perspectives. Pretty interesting stuff, I can’t imagine how it would feel breathing liquid tho, it must go against all of your bodies natural instincts and must be horrible. But it would solve so many diving issues if it was possible!
This was educating, loved it!.
Thanks guys.
I've been scuba diving since 1976 and probably half the diving I did in my life was Cave Diving concerning fluid breathing systems I think it's going to be completely possible I'm a respiratory care practitioner and I think if they set up a type of ventilator that detects when you're taking a breath in a pump is activated and assists in pushing the fluid into your lungs and the same when you exhale when it comes to initially starting the system I think they would put the person out with propofol so they're not conscious when they're drowning and then immediately take them off and start the dive
If they had an enclosed helmet they would need to leave some space at the top and some sort of surface agitator to break surface tension and make the exchange of CO/2 much easier. Kind of like an air stone in an aquarium. The air bubbles are not oxygenating the water, they are breaking surface tension and allowing CO/2 to escape from the water.
That atmosphere suit looks like something out of the Bioshock franchise amazing
I love Woody's smile at the start of every video :) but to be honest, sometimes it looks uncanny to me haha
Just thinking about it, like Woody said, there'd be a better method of transitioning from the air to liquid breathing, simple drowning just isn't on the menu, but, the physiological reactions and triggers for the drowning response CAN be modified. The coughing reflex is triggered by receptors in the trachea so they could be anesthetized pretty much like they do when intubating a patient and whole mental aversion to the idea can be dulled with some nice minor tranquilizers, some Xanax with your lidocaine sir ? oh yes please !
Just konk my ass out and let me wake up in the g** d*** thing... I'll handle it all then when I HAVE to. Making me try to sit through it willingly... um... no. ;o)
I'm a pediatric RN and loooooved hearing that there are positive implications for our CF kiddos. 💕💕💕
The movie The Abyss portrayed this SO well. What a masterpiece !
Apparently James Cameron nailed it !!! 🤣🤣🤣
