| Good question to ask, never tought of it yet!
Hello,
What we know for sure is the PpO2, so lets say it's 1.3 at 6m, then using Dalton's Law of partials pressures, the remeinder should be other gasses, nitrogen/helium, I think ! If you are exhaling more inertgas in the loop then the O2 solenoid will inject more O2 to compensate and you will end up with your lungs full and positive boyancy! Forcing you to remove gass from loop! |
