I have had problems with my Resmed S9 APAP staying at 20 cm for 2-3 hours at a time which wrecks me the next day.
This problem has been ongoing for many months and when I think I have fixed it it comes back
Using Sleepyhead I can see that during this spell of high pressure it looks like I am double inhaling.
Is this possible??
So if she didn't deal with COPD or Sleep Apnoea what did she deal with?
I think it is a simple case of the steroids keeping your airways in the lungs open when you are using your cpap.
A collar might keep you from restricting your own airways.
If the steroids work keep using them, I don't know why they thought you could do without them after you started cpap anyway?
