I monitor an RV site and a discussion about using O2 came up. I thought this reply was worth passing along.

Mike and all,
It's been a while since I studied this in school but I'll give it a try:
The air we breathe is composed of oxygen, nitrogen and other gases. The
total weight of these gases equals the atmosheric pressure which of
course decreases with altitude. The one which we are concerned with is
the partial pressure of oxygen. When we take a breath at sea level the
oxygen pressure is greater than the oxygen pressure in the capillary
beds of the lung. So oxygen is pushed across the membranes of the air
sacs of the lungs into the capillary beds and under normal circumstances
the oximetry reading is about 98%. Then as altitude increases the
partial pressure of oxygen decreases, therefore it's ability to cross
the membranes decreases as well and the oximetry reading decreases.
Normal air has 21% oxygen. By breathing nearly 100% oxygen helps us to
keep our oximetry reading closer to the normal range. Your ability to
absorb oxygen is dependent on your general health, age, smoking and
other factors.
Last year my wife and I attended a seminar at Oshkosh given by a doctor
on the benefits of using oxygen. He recommends using oxygen, as I
recall, over the age of 55 at altitudes of 8000' and higher. And using
oxygen at any altitude at night to improve vision.
Hope this helps. Any questions would require some research.

Dan,
My wife and I adhere to this now. We find that using oxygen gets us to the destination much less tired and clearer headed.
I have been using ox or several years now.

I follow the same rules. Although I'm not yet 55, I sure feel that way sometimes.

I've got a buddy that flies a lot of long x-country at 7500-12500 (now that he has oxygen). He says it's really amazing how much less fatigued he is when he lands. He now uses oxygen on all x-country flights above 5500 if he's going to be there more than two hours and any flights above 7500.
