Breathing air at 99 ft gives me 4 times the dissolved O2 at the cellular level, so why don't I feel better? If we use 30% O2 mix it becomes 6X and that makes everybody feel better. At sea level, 100% O2 gives us 5X the dissolved O2, and you already stated correctly that it does not help aerobic exercise. I agree that the hemaglobin is usually 99% saturated with .21% O2, so increasing pressure or percentage doesn't help that. It is my unscientific opinion that the culprit is the N2 and decreasing it makes one feel better. Art
