Don't some aviation people recommend O2 for all extended flights above

SportStat Pulse Oximeter - Nonin Medical, Inc.
Plymouth, Minnesota (10 miles west of Minneapolis)

A fantastic, almost magic, piece of equipment and (except for the
label) identical to what doctors and hospitals often use. If your wife's 02
saturation at altitude is consistently less than that of others, it is
certainly something to get checked. If you fly with 02 a lot, a pulse
Oximeter can save you a bunch of oxygen (because you may be able to safely
use a lower flow) and give you peace of mind.
