What I mean is that, according to my doctor, my sleep issues are fairly moderate, and that the setting of 10 in H2O was fairly conservative. And, I've had friends much higher... However, since you posted I've done a bit of web searching and see that at least one website describes the average pressure for CPAP therapy as 10 cm, or around 4 inches. Guess it's time to chat with my doctor again. Weird thing is, although the CPAP does test as accurate, 10" feels really low to me...not like when I started therapy, when 10 felt like it was popping my ears etc when it came on. As mentioned above, I've actually had it in to confirm the setting.

I use a full face mask, as I tend to have a lot of sinus issues. I might be able to use a nasal mask now, but when I started, I was having a lot of problems with open-mouth...
