Gimpy,
You describe my first weeks of PAPing. Nightmare. The post at the link DeepBreathing and Rob S gave you and one other key takeaway from the Forum solved most of my leak problem as a user of the same mask.
My Rx started at 7 cmH2O, fixed (CPAP), which caused an uptrend in my AHI. Then my DME got my MD to switch me to 5-20 cmH2O, variable (APAP?). Horrible results. But I saw advisors on the Forum recommending
raising the lower number. (In my way of thinking, the idea was to give the machine a head start when a block was encountered).
I raised the lower (5 cm) number to 7.8 cm for a dramatic improvement that helped the machine handle its load without hitting the 20 cm pressure. Currently--now a 100 days into PAPing-- it handles my obstructions about 95% of the time near 10 cm and a maximum of 12 cm. As you note, its hard to seal at 20 cm.
I rejected that F10 mask at first and got the DME to issue the Amara View. Same early problems. Then came the F&P Forma. Worse yet. Then, here, I found that linked post and the trick in raising the lower pressure.
Now I alternate weeks between the F10 and the AV and, after abandoning the recliner to get to sleep in bed on my side again (at cost of back pain), I am mostly below an AHI of 1.0, down from about 50. Leaks still occur but are now manageable at lowered maximum pressure the machine automatically sets as needed. Often the AHI recorded is just those at start up or near shut down; sleeping AHI is often zero these past 2-3 weeks.
As others said, the F10 may be wrong for you, even if great for me
now. Further, you might ask their advice regarding whether and how to change prescribed pressures. Also, I don't know the ResMed One, whether it gathers data accessible to you...for use in Sleepyhead software. I failed to mention how much help SH has been--a fantastically good and necessary tool.
If you follow those mask fitting directions you will soon feel the amount of discomfort, if any, that the mask gives at the point where leaks stop. If you cannot find a tolerable "sweet spot" where leaks stop, then you have to try some other mask or accessory.
Good luck!
