[Treatment] Central Apnea and Altitude

I like the oxygen concentrator suggestion. Maybe talk to your doctor about it?

I think O2 Concentrators tend to be very heavy, noisy, use a lot of electricity, and the surrounding air from which they are taking O2 starts to smell like it is full of ozone or something unheathy. So the machine may need to be located in an adjacent room which has open window to outside air, opened wide even in winter, and a 25 ft or 50 ft tube needed to transport the extracted O2 to the user in the next room.

So pay attention to the noise rating of the O2 Concentrator if considering a purchase.

Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment. The Advisory Member group provides advice and suggestions to Apnea Board administrators and staff on matters concerning Apnea Board operation and administrative policies - not on matters concerning treatment for Sleep Apnea. I think it is now too late to change the name of the group but I think Voting Member group would perhaps have been a more descriptive name for the group.

I live at sea level but do travel 3-4 times a year to 7,000ft above sea level. My normal AHI of 1-2 goes up to 27 even though the DME insists my CPAP automatically adjusts for altitude. NO IT DOESN'T. At the time I was using a Resmed elite 8

I talked with my doctor who told me to adjust my pressure. Even with the pressure adjusted my AHI does not go under 5.

Not sure if this helps you.

I have a concentrator; and I find the above points not an issue.

It has a small air compressor that pumps up a tank to 15 psi. The tank contains a zeolite that absorbs Nitrogen under pressure. The system then switches to a second tank for compression while delivering high purity oxygen from the first tank. You'll hear the small compressor and the switchover from tank to tank. I've used mine for 5 years and only changed the intake filter. It does not produce ozone.

Mine weighs 31 pounds, uses 350 Watts, and its sound level is 45 dBA.

Concentrators may not work so well at altitude. Since the diatomic oxygen molecule has a molecular weight of 32 while nitrogen is 28, the available oxygen at altitude is less. The machine can deliver 5 LPM at sea level; but may be maxed out at a lower delivery rate. Specs on mine are 2286 meters (7000 feet) max altitude.
