Thanks, Dave. I just read the directions that came with the monitor
(always read the directions LAST :-() and that says to use 90% of your
"customary" level. e.g. people who live at 5000 feet don't normally
show 100% but have developed tolerance so 85-86% is probably OK if your
normal level is 95%.
That's probably not a very good plan. Most people don't show 100% at sea
level, and if your usual resting O2 saturation is 95% at sea level, you
still don't want to drop below 90% in the air for the reason that Dave
S. mentioned -- the oxygen content of the blood drops off rapidly below
a saturation of 90%.
