Ted,
Foolhardy or not... there are a lot of pilots flying around like that,  and
they don't know it.I had been doing it for 7 years before I bought a Nonin and 
saw the data and got religion. I don't disagree that it is a bad thing to do.  
I sure don't do it anymore.
   BUT... and here was the whole reason to my post,  I suspect there is
something more going on here.

1) Does the Nonin accurately report  SaO2 at altitude ?It was calibrated at 
sea level or lower altitudes.

2) Is something else going on so that this rather large group of folks who
are flying around with 78 to 83% SaO2 are still alive to tell about it?
Regards,  George



>>To fly at an SaO2 of 78%-83% is IMHO foolhardy. The issue is not cardiac
arrest, it is intellectual function. The brain is able to autoregulate
