I was diagnosed in 2008, in 2012 with most recent sleep study, got a new and current CPAP (Resmed S9, Quattro Air and Slimline hose), this was great for quite a long time with AHI between 1-5. Past months have seen significant, rapid, and random AHI from 4 to 19 accompanied by headaches and the sleepyhead message of major mask leaks (sometimes but not recent) and either horrible or technically treated.
Many new supplies last month (except for tank and headgear) with good results (appears to have corrected major leak problem), specifically the hose to mask connection valve is now functioning correctly whereas before the flap seal/press fit connection at the mask leaked to the point that during operation the CPAP sound was the same as when no hose or mask was connected. New supplies have reduced AHI with most recent 3-4 weeks AHI from 3 to 7.
Unfortunately the new mask seal flutters and squeals frequently (although less than before) especially when I attempt to sleep or do manage to sleep on my back. Headgear requires constant adjustment (and has been stretched for a long time, which does not help. replacement headgear will be ordered next week (currently supplier = Lincare).
Constant leaks and squeal causes me to flop from right to left side throughout the night also causing mask seal to be compromised (but not as much). Most recent session AHI returned to over 10 but no major mask leaks.
I have had some weight loss and have reduced bodyweight ~25 lbs since diagnosed. I do notice that my bottom jaw drops after I fall asleep. The mask leaks seem to occur at any area on the seal, also the skin on my face sometimes becomes very moist which contributes to more leaks.
I am humbly requesting expertise from the Board on interpreting data, random AHI over both the weeks and months listed above and any other suggestions
Thank you for your expertise!
