I am also looking for the following information:

Oxygen consumption in function of altitude, age of pilot.


Udo, Bruno: Averages are no good - you are an individual and can vary
greatly from the averages. A finger oximeter like the SPO unit is ~$200.
Get one, use it, and you will know how well you and your oxygen system
are functioning - no guessing.

The objective is to determine when I have to go down when I see a
specific oxygen pressure in my bottle.

My EDS system uses about 100 psi per hour at 18,000', so the real
problem is accurately reading the little gage on the bottle. It's not
very precise and it's hard to read anyway, because it's small. So, when
it's a couple hundred psi from the empty point, I descend. Normally, I
change the bottle out before there is a chance it will get within 500
psi of empty.

Also, I marked the actual zero point on the gage when the bottles were
empty. The zero is off on both of them.
