Oxygen question

Hi all,

A couple questions for those who use oxygen and an oximeter. What oxygen
level do you maintain in flight? How much oxygen (liters per minute, or
equivalent rate if you use a conserving regulator) do you typically use,
at what altitude?

-Dan

I generally use enough oxygen flow to keep my O2 sat at or greater than 92%.
Without supplemental oxygen at 12000 my sat dropped to the low eighties
after around 30 minutes, which is pretty low.

92% is a good minimum level. If you want to get fancy, check your sat on
the ground on ambient, then maintain that in flight... but 92-93% is a
good baseline minimum value. The oxygen content in the blood versus the
% saturation is NOT a linear relationship (more of an S curve) and
starts to drop off SHARPLY below around 92%.

I'm not sure how we would know. I usually set it to my approx altitude.
If I'm at 12,000 feet I'll usually set it to 10,000 during the day. I'm
also mid-thirties, non-smoker, and exercise.

LOL, goes to show you how deceiving online impressions are. In the two or
so years I have been reading your posts, I had you pegged for a 50 year
old.

Well, some people who want to be able to say that they're 30-something start
counting in hexadecimal...

Well my wife says I sound like Andy Rooney sometimes so maybe that's
why.
I've been lucky to have flown a lot of cool birds, sometimes people
assume I"m older because of that. I got my private in a Cessna 140,
then got an Aeronca chief, then a Swift and now have a Mooney. I also
did my IFR pretty quick after my private so that compresses things.

Geat idea. Now I'm back in my twenties.
