My thoughts exactly

Yes, and what about the pigs? The detached coldness in the writing about the experiments on these creatures dates all of us. I find it odd how this can float by while we pine over the potential sentience of a server at Google. The acceptance of the brutality is inherent to our false sense of modernism.

Both of these issues have at their core the same question: are we gatekeeping "sentience" or I suppose, moral consideration, really - behind the rather utilitarian "so what's it done for us lately?"

I 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.

Liquid breathing hurts?

Your 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

One limitation I’ve seen on this is that the same mechanism can’t remove carbon dioxide, so this is limited to supplemental oxygen in like a surgery or emergency scenario vs a long-term alternative to say a tracheotomy.

Not necessarily as limiting as you might think. At altitude, people urinate more starting well before you are in any danger of altitude sickness because the air is too thin to breathe out waste gasses rapidly enough and the body compensates by shunting them out through the kidneys.

It's actually the opposite. At altitude you have to breathe more to get the same oxygen, and this makes your carbon dioxide lower than normal, this makes your blood too basic, so the body pisses out basic compounds to compensate.

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 viscosit…

The fact that it was an actual rat actually submerged in actual perfluorocarbons and actually breathing the stuff still blows my mind.

I 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
