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?

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%.
