@@pimp2570 did you know that mice are capable of passing down information all the way to their grandchildren through their genes? For example one generation of rats were subjected to electric shock when they were near a certain gas. To the point where their brains were conditioned to react to the gas by shuddering even when there was no electric shock. The interesting fact is, the offspring of these rats who had never been around this gas their entire lives still reacted the same way their parents did.
I mean, presumably the working context would be something like: "I drown myself for $20k a pop to fix something that broke at the bottom of the ocean."
Nope. You have a natural reflex which prevents that even when unconscious. To involuntarily breathe in water you basically have to be unconscious for such a long time that your muscles run out of 02 for the second to last thing, which is breathing and the last thing to shut down before the heart muscle. It's amazing to me how well the body has evolved to die gracefully. It shuts down system after system in order of priority so the most important functions fail last.
@@QuizmasterLaw if you trained to breathe liquid to such a point where it becomes second nature, it would be the diver voluntarily (albeit in an act of absentmindedness) breathing in water.
@@Deadbeatcow exactly. Training the brain and body to breath liquids would have a pretty bad effect when you're actually exposed to water... which is a very very real possibility in the context of this video.
Or maybe, the oxygen tanks in Subnautica are actually filled with breathable liquid. I mean that's the whole selling point of breathable liquids. It eliminates the risk of nitrogen narcosis and pressure damage.
@@xxfalconarasxx5659 Ever wonder when you get out of you're vehicle you don't feel the pressure when you are in the deepest part of the ocean, you don't get crush by the heavy water
I've drowned before and it was always my biggest fear. Even though I lived through it, I'm still scared of it because it was horrible trying my hardest not to breathe in the water. When your brain forces you to breathe in the water I went unconscious which was actually a huge relief from the stress on my lungs. I don't think I held my breath longer than 2 minutes but it felt like 30 minutes. I hope I never have to feel that again.
I would do apnea training if I were you. But then on land. Seriously, otherwise you might stay in that fear. You will find much more peace. From the sea we come and to the sea we'll go.
@@makermeeter7562 How would drowning be any different from inhaling water and passing out? Is it defined as dying from this (and having to be resuscitated to live to tell the tale)?
I had a similar thing, but I did not drown. I actually got out in time. I was being a dummy in the spa. In warm water you can hold your breath longer so I wedged myself between the railing and the steps into the spa. It's a built in spa so the railing went into the water on the stairs. Anyway, I wedged myself in and was doing it alone trying to beat 4 minutes under water. At about the 2 minute mark I realized I was stuck and started to panic. When I panicked I needed to surface. I used up my oxygen when panicking and couldn't get above the water. I was very lucky that I would train to hold my breath longer and longer because I thought it was a cool party trick or I would have drowned. I had to turn my body where my stomach faced the top of the water and I got myself out. Another 15 or 20 seconds and I would have drowned.
@@Psilocybism ive drowned before and became unconscious and it was scary at the time but im not permanently scarred forever. I still swim and have no problem getting in water but i am afraid of drowning again
ItsDomEnik It was hard enough to convince my brain it was safe to breathe when submerged back when I was learning to scuba dive. The idea of trying to convince my conscious mind to breathe in liquid seems like it would be impossible.
Playing diving games in VR I can feel an impulse to hold my breath and have to have my neocortex order the lizard brain to keep breathing. ;) "Belay that, lizard brain. It's not real water." "Fecking neocortex voodoo..."
I somehow forgot they had a freaking rat actually breathing liquid in the movie! In ICU settings, outside of artificial surfactant, the problem has always been emptying the lungs, as you mentioned earlier. I think a lot of people regard it as a dead end unfortunately.
Also, the viscosity of the liquid causing damage to the delicate alveoli would seem unpleasant and irreversible. Also, how to suppress the drowning reflex?
Out of some weird morbid curiosity some time ago, I was researching what it felt like to actually drown, and quite a few of the people who had drowned and survived said that the worst part was the panic right before hand, and the slight pain of actually taking in water, but immediately afterwords (with lungs filled with fluid, but not yet dead), they reported that it was quite peaceful and actually painless, much less terrible than what they would have expected it to be. This is quite mind blowing, imo. Now I'm not saying it still wouldn't suck to have to do it, but maybe it's not quite as bad as one would expect?...
I am sure you'd need to get some practice at it, but the human brain does lots of strange things remarkably well with repetition. For example.... if you put on a pair of inverting lenses -- i.e., "eyeglasses" that invert everything... you will need help going everywhere for a couple days... then, all of a sudden, your brain flips a few circuits around, and Voila!! you perceive everything as "rightside up". NOW, if you take off the glasses, everything is upside down... but after a few more days, the flip reverses, and things are back to normal. Do this multiple times, and the time it takes to "flip" things gets shorter and shorter. My own guess would be that the drown response would likely suppress itself after a number of such events.
@@nickbrutanna9973 my thoughts exactly. The thing that would concern me is that this developed comfort of inhaling liquid could be dangerous when in non oxygenated water
I think I heard about an experiment where a woman had lost the fear response due to brain damage (i think she was missing an emygdala?) The only thing that was able to trigger a fear response was drowning/asphyxiation. Just goes to show you how instinctual that fear is
@@szili76 sounds boring, fear is a emotional response. Who the f'k wants their ability to feel, to be less? Makes you less human in a way... Also most people that have it... die young. Keep in mind, ignorance IS bliss. So these people won't ever know what they are missing... still sad though. Fear, has a job in love too.. IE the fear of a first kiss, or fear of asking a date out. Fear is just not fear of pain and death.
Daamn ! I alerady have slightly damaged emotion drive cause I hated them ( Back in my school days I saw emotions and sexual needs as usseless trash) and suppressed them , which caused me to be unsure if I trully like something I like- so now I am less human which is not cool or fun in any way😞
This happened to me as a kid on holiday, I was swimming underwater and my leg got stuck. I was holding my breath for what felt like ages. I had my hand stretched out, out of the water, and kept it there in case someone saw me. I ended up breathing-in the water 2-3 times, although scary It was surprisingly easy. Literally, 10 seconds later my dad came by and realised what was going on, freed my leg, and dragged me to the shore. It hurt coughing up the water but the breathing part wasn't horrible, the fear of drowning was the bad part.
Actually the deepest actual dive was 534m, the 332m is from a recreational dive. The deepest pressure anyone has been at was over 700m but that wasnt an actual dive.
@@ftoalan in the game you clearly have oxygen tanks and rebreathers though so no he is not holding his breath. I think the fact that you have so little time is just supposed to act as a means of survival game mechanic. If the oxygen had as much time as IRL it wouldnt be very challenging would it
@@dullen2810 yes of course you are completely right. It was not what I was trying to say though, my point is that someone said that the person in subnautica is holding their breath but you have tanks and rebreathers. Even at like 50 meters deep the O2 time is obviously extremely limited as to not make the game too easy. Hope that makes sense
She is wrong about it being in an artery. It's way more demanding, invasive and dangerous to put it up an artery than in the adjacent vein, which stores more of the CO2 on top of that.
Yep, the movie The Abyss immediately came to mind while I was watching this. Seems they were spot on. I cannot imagine taking that first big fresh breath of..liquid.
@@tylermech66 wanna hear something worse? our sensation of drowning is not related to how much oxygen is in our blood, but how much CO2 is. so the rat was absolutely feeling like it was drowning the entire time.
Neon Genesis Evangelion came to mind actually, with how eva pilots are submerged in an orange liquid that's ionized and is the same density as air. Yeah, I'm a weeb, I know.
and then drown yourself... only oceanic or extraterrestrial exploration ignite a passion strong enough for me to not instantly abandon this line of tech potential
@@alexnaturalis1179 Hell, I would probably do it for free to get the chance to walk on the fracking ground of the sea. Where no one has ever stepped before.
I wonder if using anesthesia like at the dentist on someone before "drowning" them in the liquid would potentially overcome the psychological part. Like... If you're already underwater and breathing it when you wake up, how would your body react? Would it just act normal? Or would it suddenly freak out? Really giving me a lot to think about concerning the future of this sort of technology
it would probably suppress the inherent/uncontrollable responses but someone who just woke up would be in a state of confusion and be extremely alarmed to find theyre underwater
Good point but isn't that sort of defeating the object? Divers breathe more helium at depth and less nitrogen because nitrogen has a narcotic effect at depth which affects their ability to perform tasks. I realise that we're talking about much greater than the 40 - 60 metre range that are normally the issue at depth and indeed at the c. 200m range (? "citation needed" - I've only been to half that 😂) where HPNS kicks in but I can't help thinking that the effect of either gas/depth would be considerably less than coming around from an anaesthetic with lungs full of fluid and then being asked to go and cap a leaking gas well? Personally, even in my youth, I'd have told them to stick their job!
@@AnotherIcicle I think the general anesthesia wouldn't be great for divers but it would be phenomenal for medical purposes. Put someone under, have them breathe in their liquid medication, remove all the liquid, bring them back from unconsciousness. We do a lot worse than that already.
Medical student here. I often avoid so called "science videos" on youtube as i get bored at the simplistic and often way too divulgative explanations, but man this video.. this is excellent content. The lung physiology is absolutely on point, as well as the biomedical physics. Beautifully explained!!
Noah Mead No, that's just reality for people who are knowledgeable in their field. Many "dumbed down" videos actually go too far or don't understand the subject enough to remain accurate.
True most "science videos" are only surface level science. The real intresting videos are these wich try to go even deeper into the subject and try to really explain it. Most of the time you are stuck there and have more questions then real answeres because they missed to point.
As an Open Water Diver myself, this was HUGELY interesting! I could never be a HUGE diver like the ones pictured in this video, nor am i qualified to use any of those, but it's just so interesting! (SSI Open Water Diver)
Honestly, i have NO idea, probably VERY, VERY high lmao (instructor trainer style) But astronauts and divers are different things, astronauts use things similar to Closed-Circuit Rebreathers, (CCR'S) , So divers that are qualified with that at high levels are close to astronauts (still not the same)
@Astro Viator 😳 what? Depends if they do the course. They use water to simulate zero gravity but is not mandatory for their job to be qualified by some amateur diving agencies (PADI, TDI, SSI, etc). Plus, a saturation diver, a commercial one, has different skills that a OWD or even a Trimix tech diver. Different courses, different approach. And between an astronaut and a diver is a huge difference, same like between a pilot and a sailor, to be able to do one job great is not qualify to be good in other one. You can be a diver and have problems with hight, become dizzy, or to be a pilot and have sea sick...
Wow, just you describing how to overcome the psychological barrier of trying to breathe in water makes my hair on my skin stand. It is extremely scary! Great content, I hope to see more cool science stuff from you.
"The Abyss" a movie that had the oxy/liquid used is the same premise. The oxygen-rich liquid they show in The Abyss is indeed real. In reality, though, it looks just like water; for the sake of the movie, they dyed it light pink so that it would look “special”. The rats did indeed breathe the stuff; you can see his little sides going in and out. The filmmakers would have liked a nice long shot of the rat breathing the stuff to really show it off, but the rats kept panicking and defecating in the fluid, so they had to chop up the scene. Breathing the fluid strips the protective mucus coating on your lungs, leaving you prone to infections; the rats received antibiotic injections, and they were fine. Oopps should have watched the whole video.
Breathing in breathable liquid for the first time sounds like putting in contacts for the first time, very difficult to fight the instinct but you'll get over it
The difference being that failing to put in contacts results in slight discomfort, while [knowing that] a failure in the process of breathing liquid would result in an *excruciatingly painful, self inflicted death.*
I breathed in a bunch of water once because I worked at a marina and closed my eyes when I swam under the gas dock so I didn’t lose my contacts. I swam under and when I came up I bumped my head on something that I immediately recognized as a pontoon. No big deal, I moved over a little bit with my eyes still closed and BUMP! Wtf I gasped and my eyes came open! I was not expecting a Tri-toon boat lol. I didn’t completely fill my lungs but I sucked in quite a bit.
@@brandongreene9615 hmm, I wonder if you could trick the body into breathing in liquid then. Like have someone close their eyes, and then while they’re breathing in spray a bunch of liquid into their lungs
Five rats were used for five different takes, all of whom survived and were given antibiotic shots by a vet. The rat that actually appeared in the film died of natural causes a few weeks before the film opened. According to James Cameron, the scene with the rat had to be edited out of the UK movie version because "the Royal Veterinarian felt that it was painful for the rat". James Cameron repeatedly assures that the rats used for this take didn't suffer any harm...IMDB. Where did you get your information from?
@@DeltaH-9 : Orson Scott Card took the screenplay for the movie and wrote a book about the movie. He mentions in his book that they only did that scene with the rat one time because it traumatized the rat too much. But that was real, the rat breathing the liquid. I first read about that liquid breathing in "Popular Mechanics" magazine in the spring of 1983 so when the movie came out in 1989, I new that was real.
@@stevewilliams3850 I know it's real, but an interview with James Cameron said there were 5 rats, one suffered cardiac arrest and he revived it and then proceeded to keep it as a pet for a year before it died of natural causes.
When I was a young child (7-9), I had a re-occurring dream about falling into water. How I got into the water changed each dream, but in all of them, the result was the same. This was in the early 60's, when the news would sometimes report on this theory of liquid breathing and a child's imagination in how it might happen. To this day, I can vividly remember these dreams as if they actually happened in real life, no different than I remember trips to Disney World, family reunions or my first puppy. I only wish I could be around to see this science come to fruition.
Those types of dreams are likely actual experiences from the you that exists in alternate dimensions. You can tell that is what is taking place due to how real they are. I have had some that were really weird.
@@3bydacreekside There are some really strange ones Garrett. From riding my bike along the Great Barrier Reef, to being able to win swim competitions because I never had to "come up" for air, to working for the military planting underwater mines and bombs, cameras, sonar stations and so much more. All of this is strange to begin with, but what makes it even more baffling, is that I was still this same child 7-9 years old and doing all of this adult stuff.
LCL was basically Angel Blood from lillith It makes sense that a super god like being with super rich blood would essentially be useful as a breathing liquid for a lesser being of similar genetic lines. Ironically we now have 5 types of PFC currently in testing 2 are successful one is used to help babies who were born prematurely as ironically babies are capable of breathing a liquid medium instinctively, and one other type is used to pass oxygen and nutrients in a body well a patient waits for a blood transfusion or loss too much blood the last one indicating we have essentially made a primitive form of LCL.
QUESTION: If we can remove the CO2 via the veins can't we just oxygenate the blood that way and skip the whole breathing thing entirely? The urge to breathe is caused mainly by CO2 build-up so having oxygen directly delivered to the blood would be like discovering you could hold your breath comfortably for a *really* long time. Although you may need a lungful of liquid just to prevent your ribcage being crushed by the pressure.
If you're talking about having external equipment, why not go with an oxygen tank and breathing apparatus? Or are u think of something that would be smaller & less bulky?
We can breathe outside of the body - it's called ECMO but it's bulky, expensive and requires big catheters into major vessels which makes it difficult. I don't think any solution that requires being catherised into vessel that, were there any problems, could bleed You out fast, is a viable method for industrial use. Femoral vein catherisation is no joke and is dangerous even in clinical settings. Underwater, on a boat? Asking for septicemia. It requires pumping blood trough several filters and membranes as well as oxygen tank but it , even if not for the above, it wouldn't solve the problem of nitrogen dispersing into tissues.
I mean it is possible but the machines that allow this are pretty big so there is to be a ton of research on that too. But i think allot of people would not do this just because off something is pumping your blood our and oxygenates it. Even to think about those maschines gives me the creep. Yeah they are used in medicine but this is another scenario, you have basicly no choise. But on the other hand some people would do this so why not trying.
I've been getting into deep sea things lately too. It's a closer form of space travel to me. Good to see you taking a similar interest Real Science : )
Why can't the liquid be slowly introduced into the lungs, as with a fine mist, the particles getting thicker each minute, until the diver has accumulated enough oxygenated liquid to trick the brain into thinking it is not drowning?
That’s smart but I’d imagine it would still be extremely uncomfortable and feel it go into your lungs but at some point your gonna have to put the liquid in the mist would take very long
I've had numerous dreams that as long as I breathed shallow and fast I could breathe under water,it's actually awesome I love those dreams exploring the ocean.
@@CutMeSomeSlackTheVII yes if there are things the brain cannot comprehand it will just work different in dreams. It is like dying in a dream, you will just wake up or not die because the brain cannot fill the gap. Or some other things.
ugh. just imagine the panic when the liquid gets into your lungs. i'd like to hear more about the human experiments. how did they even persuade that guy to try that? also, i think there is a drowning reflex triggered when liquid goes into your lung, which is the reason why waterboarding torture is so effective.
i was once doing exercises for my scuba diving license. one of the exercises requires you to breathe through your breathing apparatus without using goggles. but it just felt like i was drowning. it didn't matter what i did. closing my eyes, being in a pool rather than a lake or being right next to the surface. i just couldn't convince my brain that i was not drowning and i couldn't breathe. despite knowing that i can breathe just fine. and as soon as i put the goggles back on it stopped. the brain wierd.
I've been water boarded... .my respnse: that's it?? all this hype about... that?? .... what a bunch of pussies. I didnt freak out at all and really didn't think it was that bad... its on video
I found this video narration to be of the highest standard of accuracy on this relatively obscure subject! How refreshing to hear factually accurate explanations from someone familiar with the topic. As a consequence of the superb narration I am happy to subscribe!
I agree the cetaceans figured it's easier to increase oxygen carrying ability to enable deep long dives. Xenon therapy is shown to increase oxygen carrying capacity. A tolerance to the narcotic effect of Xenon must be overcome first.
@@pprav987 not that much, its only bad in salt water and stuff like that. under water in a pool with chlorinated water is actually fine, though seeing is blurry
Narrator: It's hard to imagine any amount of training that could allow you to overcome the instinct of sheer panic. *shows video of PJs practicing preparing to drown calmly*
Ever since I saw the abyss.! I've been thinking about that scene with the mouse. It seemed to me that it would be a great way of flushing a person's lungs if they had been smoking cigarettes. Or even a medical treatment that could probably cure other lung ailments.
I have dreamed of doing this my entire life, ever since seeing Abyss. I am fascinated with this theory and truly hope during my lifetime it becomes a reality. I believe there could be some unknown spiritual breakthrough we could discover during the process of trying to convince your body to breathe liquid. In theory, your brain thinks it is dying, so you would be experiencing those final moments just like anyone else who is dying. But you wouldn't die. So all the chemicals released in that process could finally be examined and talked about. You could explain what you felt and experienced because you would be alive after the experience. I honestly think this could be a monumental step in spiritual growth or enlightenment that we have yet to discover. Deep in my soul I feel a need to experience this feeling.
Good to know I'm not the only one who thinks so. Even though I never thought of something spiritual and just wanted to try out the feeling to have liquids in my lungs without drowning lol
@Thomas Pickens have you ever watched evangelion or are you judging an entire series (that you don't even fully know about since you said that it was released in 2007 when the original series is from 1995) just beacuse it had a small element inspired by a different thing?
@Thomas Pickens if you go by your logic, then the abyss ripped off real world scientists, because they thought of it first. Also, are you serious about the "ripping off" Christianity and Judaism or are you just joking, because I can't tell
@@dhdkhdd6017 honestly thought it was a boring show. And the last two episodes were just garbage, with the main character just being annoying throughout the show.
The drowning part can be avoided by sedation when switching. Also, we could start living underwater, so the changes dont need to be done that often. imagine the possibilities of colonizing the sea. Saves on showers as well ;)
@Honudes Gai dead ass though and this is coming from someone that can spend an entire day in the bath. It's great for decompressing... until you get out and it feels like blades all over your hands and feet.....
I've been water boarded.... honestly ... it didn't bother me.. which is weird because drowning is my biggest fear... but idk... when it was over all I could think was.... "that's it?? That's what all this fuss is about.... bunch of freaking pussies." And I'm not a tough guy by any means
@melonman4037 lol... um... I could tell you... but... 1... you probably wouldn't believe me... and 2... its NSFW 18+... OK fine.. I was doing a shoot for an extreme BDSM adult film and that was part of it ... but we didn't fake anything.. it was 100% real. But of course in the back of my mind I knew my life wasn't really in danger... which probably helped... Don't get me wrong tho.. its still not a pleasant experience by any means and wouldn't want to do it again... but calling it international war crime torture.... I dont think so... not compared to the rack 🤣
This sounds to me like it needs to be a non-toxic liquid that can hold oxygen and co2 and also evaporate by itself after a given time to be able to go back to breathing air. Sounds like a tall order.
Talked to a navy dive instructor years ago about breathing liquid and he agreed that yes it's possible at shallow depth but deep dives you still have a chamber behind the nose that the liquid can't get too. That's the problem area.
@8:40 actually, this might be the easiest problem to solve. While the thought of consciously drowning is pretty horrible, the switch from breathing air to breathing liquid could be achieved by inducing mild narcosis into the diver. Like, just let him black out for 10-15 minutes, and when he regains consiousness, he'd be breathing liquid, without having to go thrugh whole drowning process. It could ease the transition significantly. Of course, that still leaves other problems mentioned, and also introduces another variable in a way of possible narcosis drug interacting with PFC, but still, with how ridiculously many substances can induce blackout into regular human, a solution could definitely be found.
My brother thought he could breathe liquid. So he jumped into the ocean a few years back... I assume he can breathe underwater because I’m still waiting for him to come back up to the surface...
I can remember the first time I went snorcheling (is it spelled that way?) and I had my head below water, with the goggels and all, but I just couldn't take a breath, because I knew that my head was underwater. I got a slight shock, when I basically forced myself to take a breath, because my body just assumed that I would kill myself. Wasn't exactly a fun experience... But now I imagine it with actual fluid touching my mouth and nose, not mechanical lines up to the air. Trying to bring myself to open my mouth and breath it in... That wouldn't be a _slight_ shock, I guess I'd just die from cardiovascular arrest...
I had the same experience too, at the Red sea it was horrible. I never adapted to see the beauty. I was in my 30's my idea was to buy some and practice in the bath but I never got around to it.
It kind of feels like, that if you are already scrubbing blood for co2, you could also oxygenate it at the same time, before returning it to the body, taking the whole breathing out of the equation. You could then fill lings with whatever liquid and be done with it.
talking requires air to pass through your vocal cords causing vibrations, id imagine it would feel like your in a constant state of drowning and your body would probably immediately go into a fit of coughing/vomiting in an attempt to expel the liquid from your lungs which are absolutely not designed to have liquid in them, and even if its possible imagine the effort of breathing when youre tired... thats just air, now imagine the effort involved in pushing liquid in and out of your lungs, you'd get exhausted quickly.
Then suddenly mentions the cyberpunk games cyborg who is essentially a human shark who breathes in air and water... Then mentions the furry cyborgs who use actual animal skin grafted to the body...
The movie, "The Abyss"! When I was a child, I repeatedly had dreams of diving into the water and breathing it in like air! I would turn to look up at my friend's and say, "Come on in, it's easy! Look! You can breath down here, just take a deep breath!!" It was wonderful!!!
When your lungs fill up with liquid, it doesn't hurt like you think it would. When your lungs fill up you lungs just feel full without any pain. Its quite peaceful really ...
I guess you could handle the entire breathing process just through blood, and the diver keeps rebreathing the same helium or another harmless gas as a placebo, but even then being entirely depended on some mechanical apparatus hooked up to you veins while trapped in a suit deep underwater doesnt sound pleasant
no, the problem we're trying to solve is having gas in your lungs, that's what makes it dangerous to dive too deep. if you were to exchange O anc CO2 via an external device you'd still need to breathe in some kind of inert liquid to not die underwater, you just wouldn't need to breathe it in and out
@@nddragoon Like you said, I think you could do both. An artificial lung hooked up externally to replace oxygen and flush out CO2, and have a liquid in your lungs to deal with pressure. Also, I'm not sure if having an inert gas like helium would cause problems because the biggest reasons we can't breathe atmospheric air at high pressures is oxygen poisoning and nitrogen in the blood. Maybe Helium could provide support to the lungs while the external device actually handles gas exchange.
Might work, but use Argon instead of Helium. Otherwise the support crew won't stop laughing when you try to address some critical emergency while depressurizing.
@@mennovanlavieren3885 I believe deep sea divers do have helium in their air mixture. If you listen to some radio chatter like when Scuba divers rescued a man who'd been trapped underwater for 3 days, you'll hear high-pitched talking to the surface crew. It's almost as if they spend months training to stay calm under pressure... pun not intended.
I've always wondered this because oxygen liquid compounds that can help with "hyper sleep", long term space travel or help with flying jets allowing higher g forces will be interesting to see this tech being worked on and maybe help with further exploration of our own planet
I remember when 3m ran a commercial in 1967 after Inventing PFC's. The Mouse breathing in it was amazing. In the Navy I met with men that did the breathing test. Years later working in defense I worked with PFC's for the other amazing qualities.
For sea floor work, given the huge budget, why not empty the lungs and rely on plasmapheresis? That's external blood cleaning, and in this case oxygenating, equipment connected to the femeral artery like you show a scrubber. This allows more processing, and additional blood storage ('donated' and stored in advance), for much wider safety margins and biological data collection for iterative improvements.
I would like to try "drowning" with liquid breathing just to know how painful it is. I guess it would be better if you had valve in your lungs so it would generate a circle powered by a pump. And is it possible to do a pressure regularity for you ears with liquid in your lungs ?
I had always thought the solution lay in bypassing the lungs altogether by oxygenating the blood and filtering it via an external pump the same way it's done within kidney dialysis and had assumed something like that was already being done for people who get lung transplants.
Does the action of breathing or to be exact the mechanical part of the contraction and expansion of the lungs need to be done? Because couldn't you insirt a tube to pump in PFC and pump out PFC at a constant rate equivalent to one breath?
imagine an pulse oximeter with an alarm and light but noticeable shock that goes off when your o2 and heart rate drop below a set parameter, these pulse oximeters exist but without the shock obviously.
