Subject: Re: Nitrox and high altitude diving

now as you might judge by my .sig, i don't know anything about 
physiology, ..so here's my uniformed GUESS on why hypoxia could be an issue:

-when breathing high ppO2, the perfusion of blood is reduced to many 
tissues (this is one reason why you do't get "full credit" for diluent 
off-gassing when breathing O2-rich mix). If you suddenly change to low 
ppO2s with the poorly perfused tissues, then you might have to consider 
hypoxia.

regards, em
