ELI5: What is Liquid Breathing and how does it work?
gpt
Liquid breathing is breathing an oxygen enriched liquid instead of a gas. Oxygen will be able to dissolve in some liquids in high enough concentrations that it is possible for your lungs to extract enough oxygen from the liquid to stay alive. The advantage to using liquids and not gas is that gas will compress under pressure which can cause complications in some cases. The two main areas where liquid breathing may be used is in deep sea diving where super compressed air makes things more complicated and for high force maneuvers in jet fighters and rockets where suspending the body completely in liquid can prevent g-lock.
