$200 pulse oximeter for monitoring your oxygen saturation

Looks smaller at flight level 240 it was minus 24 C and I had gloves on it
was bloody cold I do not think I would take the gloves or glove off to see
my saturation.

The best thing when wave flying is to breath oxygen for a hour before the
flight or going above 8000 ft thus saturating your body with oxygen.

It worked for me http://www.mals.net/bunyan04/pages/Picture%20001.htm

My understanding is pre-breathing is mainly to reduce the nitrogen
levels in your blood, not increase the oxygen. It does help a lot of
pilots to turn on the oxygen early on the way up, to compensate for
reduced lung function due to age, smoking, and other factors. Some
pilots don't get full saturation just standing on the ground!

An oximeter will let you determine this, and perhaps alert you to
inadequate oxygen in flight, whether due to those factors already
mentioned, or equipment problems like a leak, kinked hose, bad
regulator, low pressure in the bottle, and so on.
