If you get off your high horses, and read what has been writen we might be able to get somewhere. Mavericks and Quacks..........i'm neither, and unless you are an expert on hyperbaric medicine, my guess is your guessing, and if a concept is new to you doesn't nesecerally make it wrong!
The fact is that hight PpO2 for a prolonged time do cause 'capilaries' to restrict on a polmonary level and therefore inhinit the gas exchange at this level, not in the arteries, and blood stream, but in the lungs where the gas exchange takes place....during deco, for example, which is why we/i take air breaks to combat this and re-open, if you like the efficiency levels, or the all famous Oxygen Window, but there is a benefit on any deco profile from lets say 30mins + not just for the CNS but for the restriction of the capillaries.
Believe it or not.
