This reminds me of the scene in The Abyss where the rat is forced to breathe in oxygen-rich perfluorocarbons[1]. I think this idea of introducing oxygen through perfluorocarbons has been explored but not sure it’s made much headway in humans to date [2]. This paper seems like a clever idea to introduce the liquid anally where oxygen can diffuse through the linings,
and to also use same liquid (because of its viscosity) to scrub the intestines of mucus, to facilitate the oxygen diffusion process.

- 0des 4y agoI wonder what effects emerge from chronically removing intestinal mucosa
- pjerem 4y agoWhat could possibly go wrong ?
- LinuxBender 4y agoI've done it. Inflammation, sensitivity to bacterium, gut pain. The mucus regenerates but takes some time. I found that in my case diet cranberry juice and mastic gum helped until the mucus regenerated. Some people with severe IBS get to experience this often. I am thankful to not be one of them.
- 0des 4y agoThat sounds horrible
- tempcarbons 4y agoResearch on perfluorocarbons in humans progressed into several inventions. Being immersed is not one, but increasing air transfer within the lungs using a spray, reducing the impact of the bends through an injection, or reducing incidence of traumatic brain injuries due to swelling is a third. There's quite a large group of doctors out there researching them.
- jensenbox 4y agoI had the exact same though - this could make the suits a reality - providing that the traveller does not need to take large doses of morphine to deal with the pain or are dosed with amyl nitrite. I bet you would be "gassy" for weeks on end - with a dangerous combination of both pure oxygen and methane - sounds like a party to me.
- Traubenfuchs 4y agoLiquid breathing hurts?
- celticninja 4y agoI'm guessing, with the reference to amyl nitrate, they are assuming that whatever is stuck up your ass to facilitate this breathing process, is going to hurt.
- Tildey 4y agoYour anti-drowning reflex kicks in, which is fairly unpleasant, and I don’t imagine the lungs are used to a fluid with that much viscosity or mass
- jensenbox 4y agoThe article is not referring to using your lungs to breath... I can only imagine they way they are indicating the administration of the oxygen would be painful.
- kayodelycaon 4y agoHaving gas pumped into you intestines is quite unpleasant. (Woke up mid-colonoscopy, not fun.)
- yellowapple 4y agoThe fact that it was an actual rat actually submerged in actual perfluorocarbons and actually breathing the stuff still blows my mind.
- Angostura 4y ago"He's diggin' it"
- dTal 4y agoCameron seems to make a big deal of "the rat really survived" (5 rats, in fact), glossing over the fact that the shocking animal cruelty was also real. It's rather hypocritical to pride yourself on the realism of the scene, while cutting all the parts where the rats defecate from panic.
- Andrew_nenakhov 4y agoYou better not know what else scientists do to rats. And please, don't even start on the argument that they do it for science and not for entertainment. Entertainment in the form of science fiction is crucial for inspiring new generations of scientists.
- dTal 4y agoIt sounds like the next generation of scientists could benefit from inspirational films showing less animal cruelty.
- wolfram74 4y agoIf you insist on knives without any blood, you'll be looking for a very long time.
- Rechtsstaat 4y ago> You better not know what else scientists do to rats. Most people know what scientists do to animals—there have been enough awareness campaigns over the years. Animal experiments are tolerated, and usually strictly regulated [1], because they can potentially improve the lives of people. > Entertainment in the form of science fiction is crucial for inspiring new generations of scientists. I don't see why that (if it is true at all) is a reason to abuse animals for movies. If you wanted, you could make 'inspiring' science fiction showing harm to animals by using special effects.

- xphos 4y agoI don't have the source but the navy tried something similar for allowing scuba divers to fill there lungs with oxygen rich liquid I don't think it was perfluorocarbons but the ended canceling the project because while they could oxygenated someone they were unable to exchange out carbon and ultimately the person they experimented on (yes human experiment) died from CO2 toxicity. Id be interested to see how long they can ventilate an animal like this
- aaron695 4y ago
- esauce2849 4y agoAny chance of a source on this? People dying during research like this is definitely on the extreme end of things.
- Enginerrrd 4y agoAlmost everything we know about all the ways diving can kill you comes from the US Navy's experimental diving unit. A lot of people died after they intentionally gave people the bends.
- efkiel 4y agoIf I recall correctly, similar experiment have been tried lately, where the subject survive. (maybe because they were shorter than the navy's one) However, the subjects stated afterward that they felt adequately oxygenated, but also were on the verge of panic due to the constant feeling of drowning induce by having your lungs filled with liquid. None of them felt like they would be able to do any kind of productive task in this state.
- elliekelly 4y agoWhenever I have a tiny bit of water “go down the wrong pipe” I think about how truly awful it must feel to drown. Just inhaling a teeny tiny amount of water is so uncomfortable and sometimes even scary even though you can still breath and you know everything will be perfectly fine. I can’t even imagine how awful that sensation must have been for the people involved in this experiment.
- sandworm101 4y agoThe last I heard, this form of liquid breathing may have use for premature babies. The concept is that their lungs may better handle liquid than air, so long as they don't start breathing air. It would require a respirator that pumps liquid, a tricky practical problem.
- ararar 4y agoWhy can't this be repurposed as a lung cleanse? I imagine that heavy smokers' lungs (or coal miners') could benefit from a wash and rinse, perhaps with some vibration assistance. With a medical team standing by to resuscitate.
- Arrath 4y agoGod knows I've breathed in enough silica dust that I could go for something like this.
- RosanaAnaDana 4y agoMight cause more damage on the way out.
