Yeah I believe some degree of liquid breathing tests were done for divers as a way to prevent the bends or let them dive into higher pressure areas. It was noted to, of course, be fucking terrifying until you reached a point where you recognize you should've drowned but were still alive and fine. I think with divers they even rig up some sort of vibration detectors so you can even still talk (sort of).
The test candidates report that the whole ordeal was traumatising and mentally challenging as they dealt with trying to focus on breathing and battling their innate instinctive understanding that they are drowning.
Idk if drowning is innate or a learned reaction. If babies are breathing embryonic fluids before they are born, could a person theoretically be raised in this fluid and not have the feeling of drowning having not known anything else?
@@gabrielledragonfly4525 drowning is a process. I am not so sure about babies but I have a theory that in the womb they just aren't functional yet, because the point of growth in a womb is because the body doesn't think the baby is ready to face the natural world yet. What is innate is their understanding that they're drowning and so their instinctive reaction. Like shutting off their windpipe which would definitely cause asphyxiation

They actually did this for the 1989 film "The Abyss" where they demonstrated the use of oxygenated fluorocarbon fluid by dunking a rat in to it. The thing is, the scene was real. They used the real fluid and shot the scene with 5 different rats, all of which survived the experience.
@@matthewsalmon2013 pfas are a wide range of chemicals; some aren't toxic although it definitely is a good idea to stop dumping them in bodies of water
Fluorocarbons are usually quite stable and not toxic, though your body can mistake it for hydrocarbons and they decompose into some nasty stuff in certain conditions, but you’re not gonna breath in it long enough for those to happen anyways
The military also allegedly did research and trials on liquid breathing, for things like Navy Seals and such. It was extremely mentally traumatic according to those who were involved in testing and observing the tests and would have involved too much extra training and further development to be even close to usable. Thus, it was abandoned, as far as we know publicly.
Air force picked it up for... extreme g ... craft. It's used to fill the gaps between organs and in the lungs because those spaces with extreme g forces will kill you.
Yup! I’ve been adding this blurb to some other comments, but for those interested; “In the course of this research, US Navy diver Francis J. Falejcyk became the first human to breathe both oxygenated saline and PFC. Despite receiving no medication except for local anaesthesia to facilitate intubation, Falejcyk did not find the experience overly uncomfortable, though they encountered difficulty draining the fluid from his lungs and he developed pneumonia as a result. In 1971 Falejcyk delivered a lecture on his experiences which was attended by a then 17-year-old James Cameron, inspiring him to write a short story that would eventually become the screenplay for The Abyss. Klystra’s research concluded that a human could breathe PFC for up to an hour without suffering carbon dioxide poisoning provided they didn’t overly exert themselves, making liquid breathing a viable method for escaping a sinking submarine. For more physical applications, Klystra also experimented with emulsions of PFC and Sodium Hydroxide which could more readily absorb carbon dioxide from the bloodstream. Ultimately, however, none of these techniques ever saw practical use in real world scenarios. The Navy SEALs reportedly experimented with liquid breathing in the early 1980s, but found breathing PFC so strenuous that several divers suffered rib sprains and fractures from the effort during testing exercises.”
I can't stop picturing him and his brother in the same house, his brother is just peacefully reading or writing in like a nice quiet study... And then Hank is just freaking out about mad science in the basement.
For people who's lungs are damaged and can't handle mechanical ventilation anymore (see: people with really bad covid) they do something called Extracorporeal Membrane Oxygenation or ECMO which involves pumping the blood out of the body, oxygenating it artificially, then pumping it back into the body, bypassing the lungs entirely. The whole thing's a bit brutal, but better than dying, I suppose.

I believe it was tested by the navy for diving. It would have fantastic effects on our abilities to dive much deeper distances, practically unlimited, but they ran into problems in the long term, mostly keeping things clean enough so that the lungs wouldn't get infections, even after they were drained.
@@JustLiesNOR and the UK Royal vet made they prove that the rat was ok and alive. They tried, but the rat died (after the movie was filmed, heart attack). I believe I remember right, but maybe someone can add more details.
I remember reading about doctors saving a little girl with this fluid. She nearly drowned in a lake and cpr worked, but she had breathed in a lot of debris and her lungs were failing. So the doctors used oxygenated liquid to rinse her lungs and then they'd suck it out.
Hmm I would be interested in reading about this. I wonder if you misunderstood somewhat. I've never heard of using liquid ventilation in this instance but bronchoscopy with lavage is often used in these cases. I tried googling and couldn't seem to find anything....

Reminds me of the liquid that fills the pilot cockpit in Neon Genesis Evangelion. In that case it was to also reduce impact force on the pilot, but was very uncomfortable, despite being breathable.
@@WhiteIkiryo-yt2itLCL stands for Link Control Liquid, it strengthens the neural connection between the Eva and the Pilot, while also having the properties you mentioned.
I was hoping someone would bring up this application, If i'm not mistaken this concept was considered for pilots of theoretical ultra high speed aircraft to withstand higher g-force without damaging the body. i believe that concept still required some sort to dialysis machine to supplement the liquid breathing tho
I honestly think we should have kept exploring this idea because it's an interesting concept that I think there are practical applications. If we figured out how to make the fluid more comfortable they probably would help. But my main thought is for exploration of places with high-pressure such as the bottom of the ocean and places like it you could also theoretically use this when traveling to other planets that might have different pressures on their surface. Using liquid breathing to even out pressure
Scientists can be either amazing or fucking stupid with their naming scheme. You can have liquid breathing that tells you everything you need to know. It's easy to know dominant VS recessive. But the people who decided that three of our enzyme inhibitors should be named: "competitive", "noncompetitive", and fucking "uncompetitive" should be punched so hard in their nerd faces.
Real, but experimental and never used in any practical setting. Also the actual scenes were pure movie magic, they did not put any of their crew on liquid breathing.
The rat was actually 5 rats, and they all died afterwards, though their deaths were deemed “unrelated” even though they likely were. They kept defecating in the liquid, too, so they had to do mash cuts of multiple rats. Abyss was written after a talk given by the first guy to breath liquids; “In the course of this research, US Navy diver Francis J.

I think this idea was featured in a book I read as a kid called "Dark Life," where parts of the coastal ocean in Florida had been colonized due to rising sea levels and a shortage of habitable land, and the colonists lived in perpetually submerged houses on the sea floor. The most realistic thing in the book however was that everyone thought Floridians were really weird
Whomever told you that it was impossible needs to dream bigger. And they need to stop making pronouncements about things they know little about. And they should read more.
It's possible but impractical. The much higher viscosity of liquid compared to air means it's exhausting if not unsustainable to liquid breathe manually. Secondly, the flow rates needed to maintain a proper oxygenation are so high for an adult that it's quite a violent process, not to mention your brain sending constant signals that you're drowning
The pneumonia was the part that got the programs canceled. You can't spend × dollars on someone to train them to not have a panic attack from the feeling of drowning only to get them so sick you can't use them more than once.
I have actually worked on these studies in Missouri years ago. We called it liquid ventilation. The problem was when they did the studies it was always a last ditch effort which skewed the results
bro me and my homies just be chilling with our mental an emotional trauma sipping on that "I'm scared to get my feelings hurt juice" (I'm drinking what was my coworkers)
To clarify: Audio foam doesn’t usually come in that style or thickness. My dad has had an almost identical piece of foam under the sheets on his side of the bed for like ten years. I’m 100% sure it’s a mattress pad lmao
They did this in "The Abyss" with some kind of pink liquid. That is what they used to breath while so deep undersea because of pressure related reasons, iirc.
@@emmastrange5557The scenes shot with Ed Harris "breathing liquid" were faked but they still filled his helmet with liquid, he wore specialist contacts to protect his eyes due to the high amounts of chlorine, had to hold his breath for long amounts of time. His helmet had a removable section to allow him access to a support divers respirator. Apparently the filming was relentless and neither Ed Harris or Mary Musttourneo have spoken about it since the films release.
I believe they used a perfluorocarbon. While it is possible to breathe that, it's harder to breathe something much denser than air, and I think one of the adult experiments caused pneumonia because they couldn't get all of the liquid out.
I mean, as a diver, liquid breathing could very easily make my job safer. As liquids are generally incompressible, it'd virtually eliminate any risk of the bends and of any other decompression illness
I saw it for the first time a month or two ago and I gotta say, as soon as he started describing "liquid breathing" thats exactly what my brain went to lol
They used five rats to shoot the scene. All survived. They couldn’t do it in a single shot because they wanted to exclude the panic defecation. So they traumatize five rats but didn’t kill them.
all the actors' skin was sloughing off from being in the water for so long. the scene with Ed Harris slapping Mary Stewart Masterantognio was him really having a breakdown.
There was also a few attempts at using a liquid breathing medium for divers, but it was scrapped due to the dangers leftover liquids pose to your lungs
Mmhmm. And also the stresses of trying to “breath” while having your lungs filled with liquids meant some subjects broke or sprained their ribs. It’s not wholly unpleasant for everyone, but it’s awful for some people.
It's not really "scrapped" - it was used and it still can be used today if one wishes to, say... Be able to dive into the lower levels of the sea without worrying too much about the pressure crushing their lungs and bodies. However, the leftover liquids are indeed a problem - it usually causes pneumonia if not handled with utmost care.
@@cezarcatalin1406 It doesn't really help with getting [everything] out - pneumonia doesn't need much. Plus then there will be more problems with oxygen, the flow of liquids and so on.
As someone who was a premie, can confirm that this was once used on premies because the thinking was that it would help premature lungs develop faster than if the babies were forced into an air environment after practicing breathing in utero. Thankfully my heart and lungs were fully formed. I yanked out my breathing tube twice and then they decided to see if pumping oxygen into my isolette was enough, and it was.
i do remember the researchers mentioning a whole, "it feels like youre drowning and your body will fight it till you cant anymore and take a big gulp of fluid" thing. that could be why it isnt so popular
The important part is curing ailments. There are many lung infections that currently can't be cured without antibiotics, which destroys good stomach bacteria in the process, which can cause lifelong suffering. I always wanted a good Lung Wash, honestly. Think of polluted cities in China, or Firefighter lungs.
The instance I've read about liquid breathing actually being used, it was someone who had been nearly drowned in a river, so had a lot of debris in his lungs. He was kept sedated while his lungs were flooded with the liquid breathing fluid, which allowed the crud that was in his lungs to float up and get skimmed out.
I could see this being useful in certain situations like Hank said when the lungs are compromised and inflating them would be problematic. Best solution for the feeling of drowning imo would be to put them under anesthesia and then repair the lungs to allow normal breathing, but I’m no surgeon so take what I say with a pound of salt. 😊
I remember hearing about this way back when. Physically it was apparently easy to adjust to but when you transitioned back to air breathing the shift from wet to dry would make your lungs feel like they were burning.
@@quickdraw6893The first test using saline yes, but that test was a failure and left literal salt deposits in the lung, and gave the Navy diver pneumonia from residual water in the lungs. The Flurocarbon liquid breathing was found easier on the lungs and to adjust to air from womb, partly because on draining at body temp it evaporates, without damage to mucus membranes. BUT it is way denser then water or the human body so its only use is with neonatal births that also have a collapsed lung and it all requires special ventilators that are still being refined, but from what I can see there are some in active testing as last resorts at least until we have better data. However there is some chemists working on getting this fluid mixed in with water for drug delivery like an inhailer on steroids, and that would open up liquid breathing for the rest of the possible applications; including lithobrake skydiving a "method" of skydiving that is also called "forgetting the parachute" 😅. Its pretty amazing what a liquid filled suit could provide for human durability; some estimates put an hard liquid filled exosuit with liquid breathing as capable of surving nuclear blasts provided your far enough away to avoid vaporization. (i think those estimates did not consider the strength of the hard outer shell 😂)
my mind: air is a fluid air is a fluid air is a fluid air is a fluid air is a fluid air is a fluid air is a fluid air is a fluid air is a fluid air is a fluid
It was "used" in the movie "The Abyss". In it the navy scientist says, "We all breathed water for 9 months, your body will remember!" The main star was played by Ed Harris.
I remember reading about this idea in a novel when I was 14. Dark Life by Kat Falls, a book about a post apocalyptic world where people have ventured to live underwater due to overcrowding. Thought it was just sci-fi nonsense, but cool to learn that it actually does work!
I read about this project in regards to diving, because it would remove the need for a pressurized dive suit. But, it was extremely uncomfortable and that had a real problem getting the fluid out once it was in. And if you leave fluid in the lungs, even small amounts, you'll get pneumonia.
I think a person would need to go through vigorous training. It'll always have to be a gradual process. I think the best bet would be making breathable substances with different properties so that it isnt as demanding. A gas that is thicker then air and verying levels of thickness would be the best start. Gas will lead into liquid.
Also, there are some issues with moving enough liquid to keep the oxygen and CO2 circulating. Our lungs aren’t designed to move fluid that is twice as dense as water (which is what the breathable liquid is)
Considering that the liquid medium is stupidly expensive, I kind of doubt it being used by the CIA. The main avenue of research for these breathable fluids today is deep sea diving and space exploration.
@@o0DreamCream0othe main problem (or bonus for the CIA) is that it would feel like you're constantly drowning but unable to lose consciousness. Yikes.
I heard about liquid breathing once, I heard the biggest issue was exhaling the liquid. Since it's much heavier than air, it would exhaust your lungs, and you would be too tired to breathe.
Does anyone remember the movie The Abyss? They were investigating some weird stuff on the ocean floor and to help with the pressure of the deep, they had a guy in a suit that had a breathable liquid in it. The reference the fact that we all used to breathe liquid when we were in the womb.
There's a book called Dark Life where the characters use oxygenated liquid to so that the pressure from living deep underwater doesn't crush their lungs.
Yes!!! I remember that book! I got it in a scholastic fair in like middle school once and thought it was so cool! I was thinking about this book the whole video
They used this in the movie "Abyss" to send a diver deeper than he otherwise could reach to diffuse a nuke. I believe that movie had some ground breaking VFX in it for the era.
Thanks. I couldn't remember whether it was Abyss, Total Recall, or Cocoon where they did that. I remember it was a thick, light amber-ish goop that looked like it was really painful and difficult to breathe
@@joshdavis5991 A piece of James Cameron's work I don't remember too well. I was too young to appreciate the plot when I last saw it so I don't remember enough about the movie to confirm, but it's from the late 80s and still has a 7.5 on IMDB. Not exactly a classic, but the VFX for the liquid form of the alien shows a clear lineage to the VFX for the T-1000 in T2.
I believe they also looked into doing it for deep divers, and one of the reasons why was because it may help with pressure tolerance, because air is significantly more compressible than fluid. I believe the results were that it did work as intended however breathing fluid is harder and not sustainable for long term use because it is exhausting. having that limitation and the limited use case meant it didn't really catch on.
So... they just need replace the Fluid with a Superfluid, since those have *zero viscosity.* Hmm, too bad the only ones we know about are also cryogens. :-/
One of the other big issues with breathing liquid was that it was very difficult to remove all the liquid afterwards which would frequently lead to pneumonia.
It's been used on fire victims to help clear the lungs of detritus and restore some function, though I believe only a small amount was used in each lung, with the patients mostly breathing air still
i actually heard somewhere that breathable liquid would be very beneficial to divers because they wouldn’t have to make stops on their way back to the surface. the main issue, however, was getting the liquid out of the lungs after resurfacing
It would help less than you would think. The bends is nitrogen gas forming out of blood, which is already liquid. Wait... I guess the point is you could keep the partial pressure of oxygen constant, and not add other dissolved gasses. So avoid N2 (or He) getting into our blood. Huh.
@@seamussmyth1928 perhaps if we’re talking about shrinking volume, due to liquid being denser than air. you wouldn’t get the benefit of preventing nitrogen narcosis, however, because the astronauts stay in pressurized suits and environments. also, you wouldn’t want the cabin full of liquid, so you’d have to convert it into gas again before it could be used.

Wow! My first thought was: like Neon Genesis Evangelion? :o My second thought was how heavy my lungs felt when I had pneumonia in them. x_x Still, really cool!
In the movie The Abyss, one of the deep sea divers does liquid breathing to go deeper than one normally could. I don’t know if that would actually work, but I love that movie.
Yeah, I remember seeing a tv show back in the 80s where they demonstrated liquid breathing with a mouse on stage. They explained how they developed the technology for deep sea divers to not get "The Bends" from expanding gases in their lungs/body. To be fair, the mouse did NOT look happy about it, in fact it seemed to panic for nearly a minute before settling down a bit.
The Dan Brown book The Lost Symbol has something like this in it. We're led to believe that one character has been drowned because they were locked in a chamber that filled with water, but it was something like this instead, even the person who "drowned" didn't realize they'd survived the process
It disrupts the surfactant layer on your alveoli, the surfactant layer makes gas exchange a lot more efficient. It wouldn't clean your lungs out, your lungs clean themselves out. You ever cough? That's your lungs cleaning themselves.
@@domvasta kinda like Oil on the roaches back that helps it breathe! Also why spraying soapy water on roaches kills em! - they're basically suffocating due to air bubbles blocking their breathing apparatus!
@@domvasta pulmonary or bronchoalveolar lavage is a thing. Tube through the mouth and into the bronchi, then flushed with fluid. It is used for diagnostics with tiny amounts of fluid. The cell-containing fluid can then be analyzed. It can also be used with large volumes (think over 10 gallons) for whole lung lavage in rare diseases in which there is excessive surfactant buildup. Usually, it is done one lung at a time so that the other lung can continue working. After the lung is done, it can take over after one hour for the next lung to be lavaged
When I was, like, seven I saw that scene in The Abyss and became obsessed with it. Used to pretend to breath underwater by sucking water into my mouth, but was at least smart enough not to actually inhale, heh.
its also potentially highly useful in deep sea diving or any situation where you are subjected to high pressure for a long period of time as you don't need to depressurize or something id RealScience has a great vid on it
Yee. The concept was actually used in The Abyss film and they explained how it worked pretty well. The idea of using it for exploration in harsher environments is pretty cool.

Yeah Dive Talk did a vid on this recently. Basically, you're going to die of pneumonia. And the tech will almost certainly go towards better suits rather than making divers breathe liquid, which has a range of health issues, inc. psychological trauma.
@@skullsaintdead yeah i guess "highly useful" is definitely overstating it, it more has possible implications in diving but is pretty much useless. i always joke about that when i talk with people about it, because in order to start it you'd have to drown yourself and that's personally one of my biggest frears lmao

If I’m not mistaken, it’s been used as a torture/interrogation method. A person is locked in an airtight coffin-like box and is slowly filled with the breathable liquid, but it just fills with water. You don’t realize it’s breathable until the last second when you think you’re about to die. I imagine it’s highly effective!
@@nathandam6415 yeah no water boarding is when a person is strapped on an incline with their head down with water getting poured in their face. Much worse
@linakat8490 There is no such thing as breathable liquid. Even if there was, it would be way too impractical to use for torture and kind of pointless when waterboarding is a thing. Unless you're a weirdo who enjoys torturing people SAW-style.
One of the reasons they stopped is because it's also extremely painful when you start breathing air again It might be interesting in films and things like that if it weren't for the pain too
They're talking about breathing a liquified rather than gaseous form. Which can be dangerous due to lungs not being equipped to handle pumping out liquid, it removes some of our surfactant layer that makes breathing from gas exchange in the alveoli easier, can induce panic, etc etc etc.
There is also stuff called liquid oxygen that is used for extreme deep diving. I don't really know much about it to be honest but it is meant to avoid the pressure issues of having essentially a giant compressible space in your chest
I think it's used due to needing a huge amount of oxygen to breathe. Under enough pressure it becomes liquid but i think you have to breathe it as a gas or your lungs would become around -200 Celsius
I believe it was mid 60s when my highschool.chemistry/premed club was invited to a presentation where early research on this was discussed. It seems they thought this migt be useable for deep sea diving. People had sucessfully breated in oxygenated water. The mental stress must be awesome! This is the 2st I have heard of it since then.

@@matthewsalmon2013 pfas are a wide range of chemicals; some aren't toxic although it definitely is a good idea to stop dumping them in bodies of water
Fluorocarbons are usually quite stable and not toxic, though your body can mistake it for hydrocarbons and they decompose into some nasty stuff in certain conditions, but you’re not gonna breath in it long enough for those to happen anyways
Seems kinda mean.

It was extremely mentally traumatic according to those who were involved in testing and observing the tests and would have involved too much extra training and further development to be even close to usable. Thus, it was abandoned, as far as we know publicly.

I’ve been adding this blurb to some other comments, but for those interested;
“In the course of this research, US Navy diver Francis J. Falejcyk became the first human to breathe both oxygenated saline and PFC. Despite receiving no medication except for local anaesthesia to facilitate intubation, Falejcyk did not find the experience overly uncomfortable, though they encountered difficulty draining the fluid from his lungs and he developed pneumonia as a result. In 1971 Falejcyk delivered a lecture on his experiences which was attended by a then 17-year-old James Cameron, inspiring him to write a short story that would eventually become the screenplay for The Abyss. Klystra’s research concluded that a human could breathe PFC for up to an hour without suffering carbon dioxide poisoning provided they didn’t overly exert themselves, making liquid breathing a viable method for escaping a sinking submarine. For more physical applications, Klystra also experimented with emulsions of PFC and Sodium Hydroxide which could more readily absorb carbon dioxide from the bloodstream. Ultimately, however, none of these techniques ever saw practical use in real world scenarios. The Navy SEALs reportedly experimented with liquid breathing in the early 1980s, but found breathing PFC so strenuous that several divers suffered rib sprains and fractures from the effort during testing exercises.”

The rat was actually 5 rats, and they all died afterwards, though their deaths were deemed “unrelated” even though they likely were. They kept defecating in the liquid, too, so they had to do mash cuts of multiple rats.

It’s impossible
Whomever told you that it was impossible needs to dream bigger. And they need to stop making pronouncements about things they know little about. And they should read more.
It's possible but impractical. The much higher viscosity of liquid compared to air means it's exhausting if not unsustainable to liquid breathe manually.
Secondly, the flow rates needed to maintain a proper oxygenation are so high for an adult that it's quite a violent process, not to mention your brain sending constant signals that you're drowning

They did this in "The Abyss" with some kind of pink liquid. That is what they used to breath while so deep undersea because of pressure related reasons, iirc.
The scene where they test it on a rat, they actually did have the rat breath the liquid.
They faked it for the human actors.

Apparently the filming was relentless and neither Ed Harris or Mary Musttourneo have spoken about it since the films release.
I believe they used a perfluorocarbon. While it is possible to breathe that, it's harder to breathe something much denser than air, and I think one of the adult experiments caused pneumonia because they couldn't get all of the liquid out.
@@emmastrange5557 Yeah, I figured it was faked for the human actors, but thank you for clarifying that. 🙂

They used five rats to shoot the scene. All survived. They couldn’t do it in a single shot because they wanted to exclude the panic defecation. So they traumatize five rats but didn’t kill them.

There was also a few attempts at using a liquid breathing medium for divers, but it was scrapped due to the dangers leftover liquids pose to your lungs
Mmhmm. And also the stresses of trying to “breath” while having your lungs filled with liquids meant some subjects broke or sprained their ribs.
It’s not wholly unpleasant for everyone, but it’s awful for some people.
It's not really "scrapped" - it was used and it still can be used today if one wishes to, say... Be able to dive into the lower levels of the sea without worrying too much about the pressure crushing their lungs and bodies. However, the leftover liquids are indeed a problem - it usually causes pneumonia if not handled with utmost care.

The instance I've read about liquid breathing actually being used, it was someone who had been nearly drowned in a river, so had a lot of debris in his lungs. He was kept sedated while his lungs were flooded with the liquid breathing fluid, which allowed the crud that was in his lungs to float up and get skimmed out.
I could see this being useful in certain situations like Hank said when the lungs are compromised and inflating them would be problematic.
Best solution for the feeling of drowning imo would be to put them under anesthesia and then repair the lungs to allow normal breathing, but I’m no surgeon so take what I say with a pound of salt. 😊

Great channel sir. Keep the knowledge flowing for us.
I remember hearing about this way back when. Physically it was apparently easy to adjust to but when you transitioned back to air breathing the shift from wet to dry would make your lungs feel like they were burning.
Because your lungs actually have helpful fluid in it which this method washes out.
@@quickdraw6893The first test using saline yes, but that test was a failure and left literal salt deposits in the lung, and gave the Navy diver pneumonia from residual water in the lungs.
The Flurocarbon liquid breathing was found easier on the lungs and to adjust to air from womb, partly because on draining at body temp it evaporates, without damage to mucus membranes.
BUT
it is way denser then water or the human body so its only use is with neonatal births that also have a collapsed lung and it all requires special ventilators that are still being refined, but from what I can see there are some in active testing as last resorts at least until we have better data.
However there is some chemists working on getting this fluid mixed in with water for drug delivery like an inhailer on steroids, and that would open up liquid breathing for the rest of the possible applications; including lithobrake skydiving a "method" of skydiving that is also called "forgetting the parachute" 😅. Its pretty amazing what a liquid filled suit could provide for human durability; some estimates put an hard liquid filled exosuit with liquid breathing as capable of surving nuclear blasts provided your far enough away to avoid vaporization.

Ah the LCL or as fans would call it Tang.
Exactly what I was thinking
I read about this project in regards to diving, because it would remove the need for a pressurized dive suit. But, it was extremely uncomfortable and that had a real problem getting the fluid out once it was in. And if you leave fluid in the lungs, even small amounts, you'll get pneumonia.
I think a person would need to go through vigorous training. It'll always have to be a gradual process. I think the best bet would be making breathable substances with different properties so that it isnt as demanding.
A gas that is thicker then air and verying levels of thickness would be the best start. Gas will lead into liquid.
But your lungs always have fluid in them that's how you breath What do you think air is?
@@jonathanventura9183 true, but developing a gas thats close to the density of water while also not toxic to the human body is a tall ask.
@@Youkai2100 They mean liquid bud.
Also, there are some issues with moving enough liquid to keep the oxygen and CO2 circulating. Our lungs aren’t designed to move fluid that is twice as dense as water (which is what the breathable liquid is)

*consistently survivable
If im correct they can use it for torture, considering how getting removed from the fluid is an experience similar to being born apparently
Considering that the liquid medium is stupidly expensive, I kind of doubt it being used by the CIA. The main avenue of research for these breathable fluids today is deep sea diving and space exploration.

Dude, you could do a real life Bacta tank from Star Wars. Apparently it'd be more of a torture device than a medical one, but still.
I heard about liquid breathing once, I heard the biggest issue was exhaling the liquid. Since it's much heavier than air, it would exhaust your lungs, and you would be too tired to breathe.

everyone's all "evangelion this" and "abyss that" and i'm just here to say "Metalocalypse those"
I believe they also looked into doing it for deep divers, and one of the reasons why was because it may help with pressure tolerance, because air is significantly more compressible than fluid. I believe the results were that it did work as intended however breathing fluid is harder and not sustainable for long term use because it is exhausting. having that limitation and the limited use case meant it didn't really catch on.
So... they just need replace the Fluid with a Superfluid, since those have *zero viscosity.* Hmm, too bad the only ones we know about are also cryogens. :-/
That sounds made up af
One of the other big issues with breathing liquid was that it was very difficult to remove all the liquid afterwards which would frequently lead to pneumonia.
It's been used on fire victims to help clear the lungs of detritus and restore some function, though I believe only a small amount was used in each lung, with the patients mostly breathing air still
i actually heard somewhere that breathable liquid would be very beneficial to divers because they wouldn’t have to make stops on their way back to the surface. the main issue, however, was getting the liquid out of the lungs after resurfacing
It would help less than you would think.
The bends is nitrogen gas forming out of blood, which is already liquid.
Wait... I guess the point is you could keep the partial pressure of oxygen constant, and not add other dissolved gasses. So avoid N2 (or He) getting into our blood. Huh.
Also in space exploration
@@seamussmyth1928 perhaps if we’re talking about shrinking volume, due to liquid being denser than air. you wouldn’t get the benefit of preventing nitrogen narcosis, however, because the astronauts stay in pressurized suits and environments. also, you wouldn’t want the cabin full of liquid, so you’d have to convert it into gas again before it could be used.
She didnt come up with that thought. She just wanted to sound smart.
If I remember correctly, liquid breathing can is one way to make people resist higher G forces.
Yeah but then the question is how do you remove the liquid from the lungs once all the O2 is absorbed
You don't. You get pneumonia and suffer from that until you die.
Any one else wanna go watch “The Abyss”now?
It’s literally where he got the idea;
“In the course of this research, US Navy diver Francis J. Falejcyk became the first human to breathe both oxygenated saline and PFC. Despite receiving no medication except for local anaesthesia to facilitate intubation, Falejcyk did not find the experience overly uncomfortable, though they encountered difficulty draining the fluid from his lungs and he developed pneumonia as a result. In 1971 Falejcyk delivered a lecture on his experiences which was attended by a then 17-year-old James Cameron, inspiring him to write a short story that would eventually become the screenplay for The Abyss. Klystra’s research concluded that a human could breathe PFC for up to an hour without suffering carbon dioxide poisoning provided they didn’t overly exert themselves, making liquid breathing a viable method for escaping a sinking submarine. For more physical applications, Klystra also experimented with emulsions of PFC and Sodium Hydroxide which could more readily absorb carbon dioxide from the bloodstream. Ultimately, however, none of these techniques ever saw practical use in real world scenarios. The Navy SEALs reportedly experimented with liquid breathing in the early 1980s, but found breathing PFC so strenuous that several divers suffered rib sprains and fractures from the effort during testing exercises.”
@@wokeupinapanic Thank you for explaining. An interesting idea.
Did the movie "The Sphere" also include liquid breathing? I think so, but I might be mixing that up with "The Abyss".
As I started watching thia, The Abyss came to mind immediately
I thought the same thing.
Wow! My first thought was: like Neon Genesis Evangelion? :o My second thought was how heavy my lungs felt when I had pneumonia in them. x_x
Still, really cool!
I bet your lungs got buff af
Evangelon reference
I thought that too!!! Omedetou!
Lmao LCL😂
Mmmmm fanta
Honestly, a good way to replace iron lungs. At least in a hospital setting
In the movie The Abyss, one of the deep sea divers does liquid breathing to go deeper than one normally could. I don’t know if that would actually work, but I love that movie.
Woah that's such a cool concept, and itd probably make it so your lungs don't collapse too
Yeah, I remember seeing a tv show back in the 80s where they demonstrated liquid breathing with a mouse on stage. They explained how they developed the technology for deep sea divers to not get "The Bends" from expanding gases in their lungs/body.
To be fair, the mouse did NOT look happy about it, in fact it seemed to panic for nearly a minute before settling down a bit.
Oh ha, I remember that. Except somehow my brain decided it was real and I expected it to be mentioned in this answer 😅
Fun fact: for the scene with the rat, they legitimately submerged a live rat into the liquid air
The Dan Brown book The Lost Symbol has something like this in it. We're led to believe that one character has been drowned because they were locked in a chamber that filled with water, but it was something like this instead, even the person who "drowned" didn't realize they'd survived the process
Now that you said it i began to remember it. God its been 12 years since ive read it.
And since they were basically in a sensory deprivation tank they then went on the biggest trip of their life.
YES!
@@Ki_Adi_Mundi that'd be crazy they just drop some acid tabs in the top like good luck
I've always thought this would be a effective way to clean out someone's lungs
It disrupts the surfactant layer on your alveoli, the surfactant layer makes gas exchange a lot more efficient. It wouldn't clean your lungs out, your lungs clean themselves out. You ever cough? That's your lungs cleaning themselves.
Scrub scrub
@@domvasta kinda like Oil on the roaches back that helps it breathe! Also why spraying soapy water on roaches kills em! - they're basically suffocating due to air bubbles blocking their breathing apparatus!
@@domvasta pulmonary or bronchoalveolar lavage is a thing. Tube through the mouth and into the bronchi, then flushed with fluid. It is used for diagnostics with tiny amounts of fluid. The cell-containing fluid can then be analyzed. It can also be used with large volumes (think over 10 gallons) for whole lung lavage in rare diseases in which there is excessive surfactant buildup. Usually, it is done one lung at a time so that the other lung can continue working. After the lung is done, it can take over after one hour for the next lung to be lavaged
Would it help loosen and expel mucus?
How to clean out the fluid from the lungs afterwards to return to normal air breathing?
“We all breathed liquid for nine months Bud. Your body will remember.”
New Year rewatch coming…
I was wondering when I'd find an Abyss reference! Now I know what I want to watch this weekend.
Yo momma took 9 months to make a joke and we don’t need to see what another 9 months would do
When I was, like, seven I saw that scene in The Abyss and became obsessed with it. Used to pretend to breath underwater by sucking water into my mouth, but was at least smart enough not to actually inhale, heh.
So, what you're saying hank is, given the correct conditions, i.e....a sea of breathable liquid. I could infact live as a mermaid forever 🤔
Yes
The idea sounds a lot more fun than I imagine having to push liquid out of your lungs against water pressure would be.
Flood the moon with it..... Instant mermaid world....
Your skin and eyes would not like this at all
@@Ali-mv3jc
Skin and eyes aren’t the biggest problem. Pushing and pulling all the mass of the liquid in and out is an issue.
The Abyss... "She's doing it, she ain't digging it!!!"😂
its also potentially highly useful in deep sea diving or any situation where you are subjected to high pressure for a long period of time as you don't need to depressurize or something id RealScience has a great vid on it
Yee. The concept was actually used in The Abyss film and they explained how it worked pretty well. The idea of using it for exploration in harsher environments is pretty cool.
@@TheSyanAlfaWolf oh yeah im just now remembering i heard (probably from the realscience vis) that the rat they show breathing liquid in that film was actually a rat they had really doing liquid breathing
Yeah Dive Talk did a vid on this recently. Basically, you're going to die of pneumonia. And the tech will almost certainly go towards better suits rather than making divers breathe liquid, which has a range of health issues, inc. psychological trauma.
@@skullsaintdead yeah i guess "highly useful" is definitely overstating it, it more has possible implications in diving but is pretty much useless. i always joke about that when i talk with people about it, because in order to start it you'd have to drown yourself and that's personally one of my biggest frears lmao
@@fennten8338 Omg 100% me too, of all the ways of dying that are plausible (i.e. it's unlikely I'll be tortured to death), drowning is my greatest fear. I'm Aussie and can swim well but I have submechanophobia and so objects underwater, flooded caves, bodies of water where you can't see the bottom terrify me.
Insert Vietnam flashbacks of Dmitry Rogozin drowning a dachshund in breathable liquid
I was born 5 months early! And still have lung issues due to having so much liquid in my lungs at birth and after. It’s so interesting to know more about how we apply these ideals in positive ways or at least in research capacities.
how were you created in four months
@@lucasnegrete6877 science honestly, I was the smallest baby born at the hospital in my state at the time. I weighted 1 pound. My parents signed so off on so many experimental procedures and such, that are now common practice.
I am incredibly lucky. I was supposed to have a myriad of mental disorders and health issues. But all I have is asthma and I’ve broken some bones playing sports.
But it was interesting, I had no skin when I was born and had a lot of hormone therapy to grow things.
@@lucasnegrete6877 You'd be surprised. Preemies are being successfully rehabbed more often, even the very early ones. My niece was 2lbs 2oz when she was born, dropped to 1lb 9oz, and is a perfectly healthy 16 year old girl today. Medical science has come a long, long way since the days that premature birth was usually a death sentence.
@@lucasnegrete6877 yeah, I call bullshit. The youngest preemie to have survived was born at 21 weeks, AKA about five months. And even though he had more gestation time, he weighed less than a pound.
That movie the abyss...where they have that liquid breathing so you can deal with deep dives .
I like his energy here a lot more than the SciShow format.
BY FAR. 😍
I can safely say that you are one UA-camr that has me intrigued/entertained with literally every video.
Oh my goodness I just realized Hank has the Welcome to Night Vale Books and Alice Isn’t Dead on this floating bookshelves and it makes me so happy
A fellow fan? :O nice!
@@niamhythedegen ALL HAIL THE GLOW CLOUD
I thought I recognised the colours of those books! It seemed too unlikely to me for them to be Night Vale books because barely anyone I know knows Night Vale. But now I'm really glad you pointed it out!
@@Alicia-zf3nq Yeah! I’m glad to have attracted some other WTNV fans; I think it was actually Hank that introduced me to Night Vale :)
YESSSSSSS I was so happy when I saw it!
I have a song with Powernerd called Liquid Breathing
I remember reading long ago about a girl that drowned in extremely silty water. When they got her out her lungs were full of mud and gunk. So they kept her in a coma and pumped that oxigenwted liquid into her lungs. Therefore clearing out a lot of the debris in the outflow
I remember this story, but I can't verify it.
Ah yes, lcl fluid from nge
Bro this was my first thought
The Abyss did it #simpsonsvoice
Tang lemonade
Liquid breathing: eleventh form, Choking to death.
Drowning*
Underrated comment
I heard once that repeated use of liquid breathing could lead to pneumonia due to liquid remaining in the lungs
Ed helms in the abyss. They breathe in amniotic fluid from what I remember. I was a kid that always stuck with me. Hank your channel is fire to borrow a phrase from gen z. So much content love it
ed harris? not the guy from the office
If I’m not mistaken, it’s been used as a torture/interrogation method. A person is locked in an airtight coffin-like box and is slowly filled with the breathable liquid, but it just fills with water. You don’t realize it’s breathable until the last second when you think you’re about to die. I imagine it’s highly effective!
That's water boarding.
@@nathandam6415 is it? I thought water boarding was with actual water. And much more violent
@@nathandam6415 yeah no water boarding is when a person is strapped on an incline with their head down with water getting poured in their face. Much worse
@linakat8490 There is no such thing as breathable liquid. Even if there was, it would be way too impractical to use for torture and kind of pointless when waterboarding is a thing. Unless you're a weirdo who enjoys torturing people SAW-style.
@@nathandam6415pfc liquid is a thing. Wether it was used in torture ive never found any concrete sources but the possibility is there.
tanjiro is gonna have a new breathing style with this one
Water water breathing
Great, now we just need giant biomechanical machines to fight giant space gods and the occasional screaming geometry
One of the reasons they stopped is because it's also extremely painful when you start breathing air again
It might be interesting in films and things like that if it weren't for the pain too
“If we set up a tank of fluid that is highly oxygenated” yes this is called an oxygen tank
They're talking about breathing a liquified rather than gaseous form. Which can be dangerous due to lungs not being equipped to handle pumping out liquid, it removes some of our surfactant layer that makes breathing from gas exchange in the alveoli easier, can induce panic, etc etc etc.
There is also stuff called liquid oxygen that is used for extreme deep diving. I don't really know much about it to be honest but it is meant to avoid the pressure issues of having essentially a giant compressible space in your chest
I think it's used due to needing a huge amount of oxygen to breathe. Under enough pressure it becomes liquid but i think you have to breathe it as a gas or your lungs would become around -200 Celsius
It's for storage and ballast purposes, it gets aerated before you breathe it.
I believe it was mid 60s when my highschool.chemistry/premed club was invited to a presentation where early research on this was discussed. It seems they thought this migt be useable for deep sea diving. People had sucessfully breated in oxygenated water. The mental stress must be awesome! This is the 2st I have heard of it since then. Thanks!
Aww Hank, I was so hoping you would mention scuba diving and space flight. Ah well
I saw this on Chicago med but they kept the patient sleep. I think it's traumatizing if you're awake while breathing through liquid.
Thank you this is the most interesting thing I’ve seen on youtube in a minute
It's also extremely painful transitioning from air to liquid breathing, and vice versa
