About a year or so ago I took a Diving Physiology course from the U.H. 
Med. School (Lin was the instructor; guest lectures by Yount and 
others).  One of the classes covered the oxygen window in excrutiating 
detail. I want to refer to my notes before I try to answer (my notes are 
lost in a sea of disorganization, so it may be a while).  However, I do 
remember that the important variable was the ratio of dissolved O2 to O2 
bound by hemoglobin.  When you follow the sigmoidal curve out beyond 
normobaric conditions, the "window" opens up farther by shiting this 
ratio.  More later if I can find my notes. John Crea probably knows it 
off the top of his head.

Aloha,
Rich
