Default Correct usage of Oxygen

Can anyone tell me when using an Oxysaver type canula if you are supposed to breath out of your nose or out of your mouth, or does it not matter.

The Oxysaver is designed to "cutoff" while exhaling so I believe you would be better off exhaling through the nose.
At least, that's the way WE do it.

That is what I was assuming, but nowhere that I look can I find any instructions that say one way or the other.

More than that - I think you have to exhale through your nose to get the savings benefits...

From one of the sales descriptions -

This soft nasal cannula captures 18mL of your exhaled air in a dedicated reservoir and replaces/enriches it with O2 during the exhalation process. When you inhale, the reservoir diaphragm collapses, providing oxygen-rich air to the deepest part of your lungs.

It won't capture anything if you breathe out through your mouth...


And a more scientific explanation -

Default Check out the Mountain High System

If you really want to save O2, and be sure that you are getting exactly the proper O2 delivery all the time, you should check out the Mountain High electronic O2 delivery system.

Most all of us in gliders are using this system nowadays.

Actually, if you really, really want to know you are getting enough oxygen use a pulse oximeter!

Yes, get a pulse oxymeter.
Yes, exhale thru your nose. The little moustache or pendent captures and re-uses O2 that was in your nose or throat (so it didn't get used).

I have it and love it. I have timed it and can last me for more than 22 hours around 14-15K (one person) when it is set to dispense Oxygen at 10K. It last for more than 11 hours when flying two people.

I agree with others regarding an oximeter. I always have it available & will usually attach it when on AP cruise, just to establish a baseline monitor.
