R.Carlson wrote " A well educated non diver asked me a question yesterday, and caught me flat footed. If you are at depth, why can't you hold your breath longer? You have more O2 in your lungs, and CO2 would build up more slowly. Is it CO2 buildup in the body or brain, not the lungs, that causes the breathing reflex? And yet hemoglobin can't work with the air stored in the lungs for a sufficient refresh to suppress the breathing reflex? " Do you have "more o2" in your lungs or the same amount of O2 at a higher pressure. The body is also one huge chemical reaction centre, and as we increase the pressure by decending with a corresponding increase in oxygen pressure, is the same amount of oxygen at the ambient pressure not required to do the same task. If so QED if not this would lead to the conclusion taht we are more effective ( from a body point of view) at depth, and I would suggest that this is not the case, judgeing by the state I have seen some divers in after a Deep dive.
