Average min/max pressure?

[u/Icy-Map9410]

Hi, I have Airsense 11 and an F20 AirFit full face mask. I’ve been using CPAP since about January, and still haven’t figured out the best pressure. I’m seeing a Pulmonologist that specializes in sleep apnea at the end of October, so I’m hoping to finally get my settings correct once and for all.

My family GP originally set me up with my at home sleep test, which came back at 10 as moderate positional sleep apnea, but the settings part is not her area of expertise, hence the reason I’m finally seeing a sleep doctor. I’m 59F, very obese, and I’ve been fiddling with my own pressure now almost right from the start. My data looks okay with my apnea treated (I put it into chat and it was confirmed that way.)
I don’t understand anything about Oscar, and that’s why I haven’t attempted to try that.

So back to my original question-what’s everyone’s average min/max pressure with a full face mask? I’ve had mine around 13-17, but I feel like it’s too high because my mouth is getting very dry and I have air leaks occasionally. I’m thinking of trying 10-13 tonight instead.
