This is actually incredible. I never knew people regularly worked at such depths. I feel like I got the bends just by hearing some of those depths ! Thanks
The maximum depth increased rapidly after WWII from about 200M to 400M but after 400M was reached as maximum working depth it has crept deeper at a much slower pace again. Surface fed supply is a completely different game to SCUBA.
Those deep sea workers actually work at tremendous risk all the time. there was a terrible accident in the 80's where their compression chamber explossively decompressed due to negligence by the company. the divers literally exploded like a bomb due to the rapid decompression. if there is a mercy in this, they died too fast to know what was happening.
how about 24 days of decompression? 😭 Though at least that human lab rat got to stay in the hyperbaric research chamber instead of being underwater. I hope they compensated the shit out of them lmao
They don't just wait in one spot, they go up in stages and have decompressions stops bases on calculations from their dive computers which record depth and time to calculate how long the decompression should take.

There is something a little bit misleading in the NITROX part of the video in my opinion. It is suggested in the video that NITROX allows you to dive deeper, which is not the case, rather the opposite actually. NITROX allows divers to STAY LONGER at certain depths without having to decompress in order to get rid of the Nitrogen in your body, which is totally different. NITROX can be used in many forms but if you use the usual mixes, such as Nitrox36 (though Nitrox32 is more frequent in recreational diving) you should not go deeper than about 29 meters (about 34 meters with Nitrox32) because of oxygen toxicity. And this is a very important safety matter, because you might simply die if you cross the maximum operating depth threshold. But as far as you stay within the limit, it's safer to dive with Nitrox, as you don't need to be as careful about the time you stay at depth (usually below 20 meters) as with air, because your body aggregates less Nitrogen, thus allowing you to to stay longer.
Helium doesn't help saturation divers retain heat, the fact that it is so good at conducting heat is actually a detriment as it conducts body heat away from the diver more quickly than normal.
I haven’t watched the video yet, but as a Technical scuba diver myself, the reason they use helium is because they need to DILUTE the amount of oxygen and nitrogen your body absorbs at depth. Here’s what happens: OXYGEN can kill you at depth (oxygen toxicity, causes convulsions among other things which leads to drowning), and NITROGEN is also harmful at depth (nitrogen narcosis)… at extreme depths, you’d get so drunk/high from it that you’d basically black out and end up drowning. Also, too much nitrogen absorbed = huge decompression (deco) times. And the reason “depth” makes gases toxic, is because depth = more pressure, which means that gases CONDENSE. So you absorb more molecules of gas, in a breath of air, the deeper that you go. So anyway, the reason they add helium to the gas mixture, is because helium is harmless to the body. It doesn’t “do” ANYthing, but that’s precisely THE POINT. They want you to be absorbing less oxygen and less nitrogen at depth, because at depth, the gas gets CONDENSED. So they add helium to the mix so that your body absorbs the correct amount of oxygen and nitrogen it
@@gordonlawrence1448 Most divers actually choose diving because of the beautiful aspects of diving. Most people in traffic choose the car because they need to get somewhere. It would be easier to quit diving than quit driving in every day life.
Thanks for the video. I am ultimately amazed at how many people it took to figure all of this out. This wasn't an over night, "we'll sleep on this and have the answer in the morning" kind of scenario. This took a LOT of time and deaths.
BUT! What if you wore a spacesuit to the dephs? They have they're own pressure, Atmoshpere, Plenty of protection from the enviroment, And everything else. Something to think about!
They are called atmospheric suits. Able to maintain normal atmospheric pressures at extreme depths and extremely expensive to maintain and don't have good dexterity as a diver would without the suit.
Very good question! However, space suits are more or less the reverse of those bulky diving suits. When you go higher up in the atmosphere, the pressure gets lower and lower until your body can't handle it anymore, and a space suit is designed to keep the surrounding pressure by the suit by stopping it from expanding. When you dive down, the pressure gets greater and greater until ultimately it crushed you. A diving suit prevents this by keeping the surrounding pressure out of the suit by stopping it from imploding. Hope this helps
As few people said: spacesuits are designed for vacuum= less than 1 atomsphere difference-> less than -1 bar. While underwater it would need to hold +1 bar for every 10m of depth. so a suit like this have to be much tougher. at this point you might as well use a mini submarine instead.
I swear RUclips recommends all the interesting content when I should be going to sleep. Just one more i say then just 1 more and 1 more and 1 more......
I went to 142 max depth and I got pretty damn NARC’d, lol. I definitely recommend trimix if you go below 130… I was lucky I was on a sloped 45 degree wall, and not a straight-up-and-down wall. If I lost control of buoyancy on a vertical slope I would’ve been in serious trouble. Being narc’d is enjoyable tho for sure but it’s also dangerous if you’re on a vertical wall. On the other hand I think it’s pretty safe to dive to 140 on regular air IF the bottom is a “hard bottom” that doesn’t go below 150 or 160. Such as doing a “wreck dive” where the ocean floor bottom is exactly 152 feet deep.. That way, if you lose control of buoyancy, you at least won’t die and the dive master can always yank you up if you’re acting a fool. But in general I recommend being a responsible diver lol. Thankfully when I was NARC’d I didn’t do anything stupid, and I ascended (went up) slowly but steadily until I was at 120 feet, and got my senses back. Lol. When you go super deep it can mess with your head Oh and ironically I just had sinus surgery 2 days ago to make my sinuses better for life/allergies (and also for diving) and I’m on pain meds right now as I’m commenting lmao… so yeah 😂
With the mammalian diving reflex, there is an increase in systemic vascular resistance via peripheral vasoconstriction, but this would cause an increase in blood pressure, not a decrease. Wonderful video though.
The video neglects to mention that oxygen becomes toxic if you breath too much of it (at high pressure). Around 223 feet, you come at risk for being poisoned by the oxygen of breathing regular air mix Scuba gear, and much sooner if using NITROX mix (because it has more oxygen). 223 feet isn’t a hard limit, so there is no need to tell about the time your uncle dove to 260 feet. It’s just that beyond this, you risk convulsions with zero warning, which, at that depth, is going to be hard to survive.
The crazy thing beside this already achieved depths is that the deepest part of the ocean is around 11000m... This is almost 22 times deeper as the record of 534m.
"Evolved perfectly for walking and running on land"? Have you seen the rubber bands and paper clips that make up the human foot? Or the wobbly teacup stack nightmare that is the spine? We're evolved adequately at best for walking and running. 😅
One remark, sign NITROX on dive tanks... In underwater diving, nitrox is normally distinguished from regular air, used for regular scuba diving. Divers marking tanks with Nitrox mixes with oxygen proportion over regular 21%, like nitrox-32, nitrox-36 & etc.
KRI Nanggala 402 has reported drown for 850meters deep in the ocean on 22 april 2021 at 3.00pm Indonesian West Time. About 53 people inside expected still alive for next 72 for the rest of oxygen they have. 💔💔💔 It’s 25 april today and we still hope there’s miracle for them to keep alive😞

I did free dive up to 45 metres. But now I have a permanent tinnitus at my left ear, althought I never had problems equalizing nor ever felt anything painful from pressure. That's what you get for trying to break your own limits
8:05 I remember watching a video on a tragedy on one of these. If I remember, the vessel wasn't fully decompressed when a worker opened the door, shredding everyone inside to pieces. 😱😵
Just today that I have found your channel. Watched your video on what’s are the limits on human survival. Watched the whole vid through. Subscriber earned. I am now going to have a look through your vault of knowledge and see what else I can find. Really good Vids.
The biological limit for humans is 1000 meters. The increasing pressure affects the cell membrane; if the pressure becomes too high, substances can no longer diffuse through the cell membrane (oxygen, sugar, fats, etc.). Therefore, deep-sea organisms have thinner cell membranes. If you bring such animals to the surface, they appear gelatinous / wobbly due to the much lower pressure on the surface. Because the thinner cell membrane gives the cells less rigidity.
As a diver, the short and easy answer is: at the depth where the partial pressure of Oxygen makes it toxic. They try certain gas mixes to extend it but it doesn't help much, and certainly not for long.
@maxmock2661 Oxygen toxicity occurs in most people when the partial pressure of oxygen reaches 1.4 atmospheres or greater. mixes of an assortment of different inert gases can help, but eventually the risk of the toxicity of oxygen becomes to great (results differ among different people. I refer you to the National Institues of Health(NIH) concerning the "ABC's of Oxygen", and laugh in your face.
I searched for this due to Subnautica gameplay. You can sink and crush your submarine and Pronsuit, but depth pressure can't kill you or even cause Benz from resurfacing to fast. Subnautica must have magical default diving suits that instantly scrub nitrogen from your blood or something. Though your suit's O2 tank is so tiny that you'd inevitably dround if you're 17 minutes of travel distances deep underwater. Given the choice between a large 30 minute O2 tank or a magic Benz preventing skintight diving suit, which would you rather have?
Liquid breathing ran into issues of removing corbon dioxide from the blood. It was also difficult to remove from the lungs after finishing diving and caused pneumonia in one of the test divers. And test animals drowned over the course of 8 hours. What I heard of it left it as more of an unfinished scifi concept. These commercial divers who use 1 percent of thier lungs don't sound like they're in desperate need of upgrading to the fluid breathing that risks being unable to get rid of corbon dioxide waste. I can't remember the name of the vid that discussed liquid breathing but it sounded super risky.
...The aurora is a city sized spaceship sent out to build an interstellar phasegate.. it 3d prints anything by repositioning the molecules in resources you find.. I think they're a bit smarter than we are.
Simple. The submersible is pressurized to the surface pressure. This means that the submersible had to fight to keep the huge pressure difference between the outside and inside, but it failed for whatever reason. The saturation diving “pod” is pressurized to the same pressure as the surrounding water, alleviating the need for high structural integrity. Water pressure does not crush humans, it crushes air spaces. The sudden implosion of the submersible caused the pressurized hull to completely collapse in on itself, and thats what caused the death of the passengers, not the water.
Humans are mostly water, which is not compressible. The only thing you need to worry about is the gasses inside of you. This includes tissues that absorb nitrogen, your ears, and your sinuses.
For the most part, free divers are safe from DCS. You’re correct on the depth, doing repetitive deepdives in a single day or periodically in a couple of days will cause DCS but only due to deep depths
I had never heard of breathing hydrogen+oxygen to get past the maximum helium depth. But hydrogen and oxygen can combine to form water. So I'm surprised this works. The deepest I've ever been was 2,050 feet, in a home-made submarine in Roatan, Honduras. Very cool experience; fascinating stuff down there. That was on my bucket list long before I'd ever heard of the idea of a bucket list.
@@Paul-vi7kh He is right, the issue is the oxygen, not the pressure, the body is mainly water, and as long as you keep breathing the pressure in your lungs its equal to the pressure around you. If it was about the pressure you would not see marine life in deep sea. This video has a lot of BS, if you research you find what is the biggest issue with diving. You need a mixture of gases that are safe to breathe at high pressures. There is also an article that i found saying that if you could dive deeper than 1000m your chest muscles might not be able to function properly, but is just a theory since nobody reached that depth yet.
Does the volume of water affects pressure in diving deep? for example a 5x5 pool which is 100m deep with 1k gallons of sea water vs 100m deep ocean with tons of seawater. Will it influence pressure? Why Or why not?
Pressure depends on depth and weight 1m^3 of liquid. Guess, ocean water is slightly different by composition to a swimming pool water (more salt e. t. c), as well the weight of 1 m^3 of water can be slightly different too. What is length, width of pool doesn't matter. Only how much water atop of you.
1. volume of waster doesn't affect diving deep - it's relatively proportional with depths, ~ 10m/32feets ~ +1 atmosphere, meaning at 20m/64feets there 3 atm, 40m -> 5 atm and etc. 2. volume affecting weight - 1 gallon ~ 133.53 oz/1.37kg , but pressure 10inch depth is same with slightly diff of how salty water is.
Lol just came from an old video of the world record being set at 315m. Reached in about 13 minutes, 12.5 hour dive! Edit: from the title, I expected more info on the many free and assisted deep dive record holders.
Former Sports Diver... still remember my instructors telling us that if we stayed above 10 meters / 33 feet (1 atm), we could stay there for hours with zero risk of the bends. Too bad air tanks can't hold enough air to spend hours underwater. I do have friends who are Technical Divers. They accept the risks and follow careful protocols. They also live in Florida and regularly dive next to sharks, gators, and other nasty sea creatures. They accept those risks as well. None of them will dive the Blue Hole in Egypt, too dangerous. I just chuckle.
How do they get use the toilet while waiting days to decompress? If they were at 1000' working depth and used the toilet and opened a valve to (flush) it would be at 445 PSI!

Liquid breathing ran into issues of removing corbon dioxide from the blood. It was also difficult to remove from the lungs after finishing diving and caused pneumonia in one of the test divers. And test animals drowned over the course of 8 hours. What I heard of it left it as more of an unfinished scifi concept. These commercial divers who use 1 percent of thier lungs don't sound like they're in desperate need of upgrading to the fluid breathing that risks being unable to get rid of corbon dioxide waste.
I can't remember the name of the vid that discussed liquid breathing but it sounded super risky.
whats the point of liquid breathing? there is a proper gas mixture for every depth.
My cousin dive about 5k meters deep, but he never surfaced, so I guess that's how deep you can dive.
😟
What a factual and interesting presentation! I will be watching it again like I usually do on videos that I want to remember important facts.👍
So tldr: subnautica has either crazy new tech, or is just impossible ^^
...The aurora is a city sized spaceship sent out to build an interstellar phasegate.. it 3d prints anything by repositioning the molecules in resources you find.. I think they're a bit smarter than we are.
@@1nstantis642 maybe a tiny bit^^
This is a very phenomenal video. Thank you
Staying underwater for 15 hours? No thanks
Came here after knowing ‘ Titan implosion’
8:26 caught me off guard 💀
10:08 they turned him into a psychopath
As a commercial diver..I was taught in school..1280 Fsw is the deepest a human can be in the water with diving gear
So you also have come here after oceangate implosion 🥴
Nobody carea
I've seen like a million videos about oceans, submarines and fish since oceangate. RUclips is flooding me with these videos 🤣🤣🤣
Scientists are the modern philosophers, they talk about real things with abstract thinking while sitting on a comfortable couch , change my mind
Ahmed Gabr also used more than 4 scuba tanks!
Just came here because of titan sub implosion 😨
Humans cannot survive at any depth (without aide) for much more than a few minutes (we cannot breath down there remember)
35 meters and my head is already felt like its gonna explode
The irony this showed up after I watched the titan submarine fail😅😅😅
Same😅😅
KRI Nanggala 402 is 850 meters 😭😭😭😭
Stu smiles like devil ahahahaha 😂😂 Love you Stu ♥️😜
😈
@@DebunkedOfficial Hahahahahah 😂😂😂♥️♥️♥️♥️
damn. This channel deserves 10m not 0.5
Thanks! 🤞 One day
I freedive 10 meters deep with no training. Mostly just shell-diving. I'm content.
That is one record I don't want to beat
I dive to 30 meters regularly, I don't die and respawn ...
thanks stu
Just can’t wait
Hope you enjoyed it!
So at that depth you could dive down and visit the Yamato Battleship and swim around it, and almost down to the USS Independence.
Using Nitrox didn't allow you to dive deeper! It's the exact opposite! With Nitrox, your maximum depth decreases!
If that submersible imploded due to the pressure how can saturation divers work on the ocean floor without their bodies being crushed
Simple. The submersible is pressurized to the surface pressure. This means that the submersible had to fight to keep the huge pressure difference between the outside and inside, but it failed for whatever reason. The saturation diving “pod” is pressurized to the same pressure as the surrounding water, alleviating the need for high structural integrity. Water pressure does not crush humans, it crushes air spaces. The sudden implosion of the submersible caused the pressurized hull to completely collapse in on itself, and thats what caused the death of the passengers, not the water.
Humans are mostly water, which is not compressible. The only thing you need to worry about is the gasses inside of you. This includes tissues that absorb nitrogen, your ears, and your sinuses.
Those saturation diving depths are insane. The balls on those commercial divers. I can't think of a more insane job.
i really want to use Respiration III, and Turtle Helmet,
i bet you holding your breath while watching this 😂
I know what you mean 😆
Romainian Unit 39 combat divers have a record for 501 m for chamber..
Thanks for the extra info 👍
Correct me if I’m wrong but I thought you couldn’t get the bends from free diving because you’re not respiring? Was it from the insane depth?
For the most part, free divers are safe from DCS. You’re correct on the depth, doing repetitive deepdives in a single day or periodically in a couple of days will cause DCS but only due to deep depths
I had never heard of breathing hydrogen+oxygen to get past the maximum helium depth. But hydrogen and oxygen can combine to form water. So I'm surprised this works. The deepest I've ever been was 2,050 feet, in a home-made submarine in Roatan, Honduras. Very cool experience; fascinating stuff down there. That was on my bucket list long before I'd ever heard of the idea of a bucket list.
home-made submarine? please elaborate sir
@@009fly Stanley’s submarines in Roatan. They’ll take you down to 3,000 feet
Pretty sure the lack of air is a bigger issue than the pressure
Pretty sure the pressure would kill you before your brain could even think to take a breath.
@@Paul-vi7kh He is right, the issue is the oxygen, not the pressure, the body is mainly water, and as long as you keep breathing the pressure in your lungs its equal to the pressure around you. If it was about the pressure you would not see marine life in deep sea. This video has a lot of BS, if you research you find what is the biggest issue with diving. You need a mixture of gases that are safe to breathe at high pressures. There is also an article that i found saying that if you could dive deeper than 1000m your chest muscles might not be able to function properly, but is just a theory since nobody reached that depth yet.
Was you a teacher at one point? You'd be a great one! Thanks for the info! Saturation divers is new to me.
Does the volume of water affects pressure in diving deep? for example a 5x5 pool which is 100m deep with 1k gallons of sea water vs 100m deep ocean with tons of seawater. Will it influence pressure? Why Or why not?
Pressure depends on depth and weight 1m^3 of liquid. Guess, ocean water is slightly different by composition to a swimming pool water (more salt e. t. c), as well the weight of 1 m^3 of water can be slightly different too.
What is length, width of pool doesn't matter.
Only how much water atop of you.
1. volume of waster doesn't affect diving deep - it's relatively proportional with depths, ~ 10m/32feets ~ +1 atmosphere, meaning at 20m/64feets there 3 atm, 40m -> 5 atm and etc.
2. volume affecting weight - 1 gallon ~ 133.53 oz/1.37kg , but pressure 10inch depth is same with slightly diff of how salty water is.
I've been 210' down on SCUBA on the shelf in Fla. off Dirtona Beach.
4:33 like for the piston legs lol
i want to know how they live on that capsule of water for a month... like, how they eat or poop
The capsule is quite large, like a well-equipped RV. It has a kitchen, toilets, sleeping bunks, etc.
And no mention of all the saturation divers that got their health totally ruined by diving to 400 - 500m...
Nice. So I can stand at the bottom of the 10ft pool without worrying my lungs will collapse or something.
Lol just came from an old video of the world record being set at 315m. Reached in about 13 minutes, 12.5 hour dive!
Edit: from the title, I expected more info on the many free and assisted deep dive record holders.
Ad ends at 1:17
Former Sports Diver... still remember my instructors telling us that if we stayed above 10 meters / 33 feet (1 atm), we could stay there for hours with zero risk of the bends. Too bad air tanks can't hold enough air to spend hours underwater.
I do have friends who are Technical Divers. They accept the risks and follow careful protocols. They also live in Florida and regularly dive next to sharks, gators, and other nasty sea creatures. They accept those risks as well.
None of them will dive the Blue Hole in Egypt, too dangerous. I just chuckle.
I would love to take a selfie at the deepest part of the ocean one day. At least if I can’t get to mars (up), I might as well go down as a legend 😂
Makes my deepest SCUBA dive of just over 50 mtrs look a tad feeble.
I have been to 22 mtrs on free dives!
How do they get use the toilet while waiting days to decompress? If they were at 1000' working depth and used the toilet and opened a valve to (flush) it would be at 445 PSI!
