So my AHI numbers have came down. Most nights it is below 5 events per hour with an occasional night of 7-8. I purchased another mask to try, since cpap.com offers free returns on most of their mask, and I really like it. It's the Airfit P30i nasal pillow mask. I don't feel as confined. The only problem is I woke up several times with my mouth open and the sound of a hurricane coming out.
To make matters worse I ordered a chinstrap from Amazon that was rated really high but it must have been employees giving it the ratings because it was big enough to fit a person 10-11 or younger. Do any of you use a chinstrap and if so which brand/kind or where do you purchase them?
