A pressure above 1 atm does not collapse the lungs, because the higher pressure is also present inside the lungs and indeed throughout the body. Your description of SCUBA is completely wrong. The gas being breathed, both in the breather and in the lungs, must match the pressure of the water (>>1 atm). Humans can handle a wide range of pressures, as long as adjustments are slow and the amount of oxygen remains suitable. | |

| Oct 11, 2023 at 1:36 | comment | added | KEY_ABRADE | @GaultDrakkor I'm not well-versed in how SCUBA gear works. However, my understanding of it is as such: only the storage tank for the mix is kept at 10+ atmospheres, primarily to ensure a lot of gas can be crammed into a small can. A little squirt of that gas gets let out into the breather, and then the valve is shut; this stops the pressure in the breather from equalizing to the pressure in the tank. The diver breathes the gas, which is now 1 atmosphere, it gets exhaled out into the water, and another little bit of 10-atmosphere gas is allowed out and then cut off. Rinse, repeat. | |

At 100m of depth a SCUBA diver is breathing a 10+ atmosphere mix. Yes there are issues at great depths, but being able to breath is not one. | |
