Altitude - Climbing above 10,000

[Deagle11]

I want to climb the 7 summits, however, after I climbed Mt Rainier I was found to have sleep apnea. I currently use a bipap machine.

A caouple of the mountains I want to climb have camps at 11,000 ft, 14,000 ft and 17,000 feet.

1. Is there a machine that will work this high?

If you have any respiratory issues (of any sort- awake or asleep) you serioulsy need to consider the health risks arising from persuing your climbing ambitions.
