I have been treated for sleep apnea for the past 2.5 years. I have probably tried 10 different types of masks and played with my settings countless times. My RDI is general under 1.0. I do not think that any more tinkering will improve it. I run a very narrow pressure spread so that my flow limitations are recorded, with fixed pressure they are not.I am using a F10 full face mask. Nasal masks will not work for me because I can't keep my mouth shut. It took much time and persistence but I HAVE ARRIVED!! This forum was my main education and I thank all of you!
Congrats and say "Hi" to Herman and Grampa.
Congrats nice to see you have it under control!
