The record for a simulated dive is 71 atm. Main problem is finding a gas you can breath at those pressures. They used hydrogen and helium with a tiny bit of oxygen so it's not explosive. Even a tiny bit gives more than enough partial pressure when you're that deep.

If someone opened the door accidentally, "instant human souffle" would probably be the best description as all the dissolved gases in the body's water content would bubble out at once.

It's not really even explosivity that's the problem - practically everything you'd want to breathe becomes toxic or has other detrimental effects at high pressures.

Oxygen, of course, loves to reach with everything, and will mess up your lungs something fierce if it's too concentrated for them to handle. It'll also mess up your eyes and other mucous membranes too. Oh, and killing off all sorts of other important stuff like "red blood cells" and "your central nervous system". So if you want to go to high pressures, you want to cut down the oxygen concentration so that once you're at depth, it's back down to safe levels. So what can you use to bulk out your breathing gas that's not going to poison you?

Nitrogen's a good starting point, right? I mean it's already most of the atmosphere and it's pretty inert. Except that it dissolves in your bloodstream and acts as a narcotic - starts with feeling a little drunk, ends up with serious hallucinations, unconsciousness, or straight-up death. So then you start using a trimix with helium, which gets you a bit further - until you start getting helium tremors due to it messing with your nervous system. That's where the hydrogen comes in I guess, except that hydrogen is pretty hallucinogenic.

Really, fluid breathing is probably a better plan. It has its own complications of course, but having an incompressible fluid providing oxygen solves a whole bunch of partial-pressure issues.

I've heard, though I don't know if it's true, that when someone falls into a manure pond on a hog farm or whatever they don't even bother with a rescue effort unless someone saw them go in. Just the concentration of ammonia and hydrogen sulfide is enough to kill you in seconds, and if you somehow survived that and didn't drown, you will with 100% certainty be infected with several different strains of pathogenic bacteria and parasites.

It doesn't solve the issue where you need to move something like 20kg of liquid in and out of your lungs every minute. Your diaphragm isn't evolved for that sort of work and you'd exhaust yourself after a few minutes.

Fluid breathing can work if you have a pump system mechanically forcing the stuff in and out of your lungs, though, so give that one a shot.

We'd also need a set of drugs that can suppress a bunch of things like trying to breathe and oh god I can't breathe. You'd need to put a cap on that so that the oxygen doesn't defuse in reverse out of the blood right?

The sensation of "oh god I can't breathe" is related to CO2 concentration in your blood. As long as that's kept in check, you won't feel like you're suffocating.

I was thinking that you'd want to stop the person from breathing entirely so that the oxygen doesn't diffuse out of their blood via the lungs (happens in a vacuum does it happen in a gaseous but oxygen free environment? I'd expect it does because it's an entirely passive process based on concentrations on either side of a membrane) and that might cause issues. Maybe I'm off base about that though

edit: is there even data on this? it seems like we're entering the end of the medical science spectrum where it becomes weird to do experiments on real people, but we do know from accidents that it happens in a vacuum or at atmospheric pressure when oxygen levels are too low or co2 levels are too high

edit 2: I'm a nuclear engineer and my last biology class was in grade 12 so maybe I'm just wrong though

The fluid-breathing stuff is an oxygenated fluorocarbon emulsion. It can dissolve more O2 and CO2 per volume than the blood itself can. Oxygen won't dissolve back out of the blood into the medium any more than it does into the air you breathe every day.

It's been used in people, chiefly in premature infants whose lungs cannot inflate fully on there own, where it serves to provide mechanical support for the lung structure while keeping the infant oxygenated.

The chief problem with using it for underwater applications has been stated: unless there's something else keeping is circulating, the work of breathing it in and out is very tiring. Also the feeling of your lungs filling with it in the first place can't be that great.

You need oxygen to be dissolved in the blood. If it's present as gas then all you'll achieve is blocking the veins and killing the subject.

I think you're referring to a heart-lung machine. It's commonly used during heart surgeries to pump and oxygenate blood while the heart is stopped.

The reason IV's are hung is so gravity assists the flow. Connecting people via IV tubes with no kind of automated pumping probably wouldn't work for long. If it flowed at all it would be slow, so clots would form and the flow would stop.

Maybe some sort of maypole configuration? Each person has one arm secured to the 'maypole' in the center, so that there is only a couple inches between the arm and the next arm in the loop. At that distance you might even be able to directly splice the veins, so you wouldn't need IV tubes at all.

I don't think that would be enough so that you could only feed one of them and let nutrition flow from vein to vein though through the whole system though. Arm veins are tiny. Leg veins might work better.
