CPAP Titration and Altitude Changes


#1

I have noticed a change in my AHI Index from 2.3 to 30.4 while on vacation at a high altitude location (7000 ft.). Is the altitude creating this change and if so, should I be adjusting the CPAP pressure?


#2

to best of my knowledge, it depends on what year, make, and model of machine you are using. The newer machines are designed to adjust to altitude. Regardless there is still lower abundant oxygen the higher up you go.

I know of someone who lives at a high altitude and has had problems getting her doctor to adjust her CPAP machine accordingly. It would be good to check with your doctor if you will be traveling again or staying at a location with high altitude. This is something most people would not be aware of!
