Last night I switched from a full face mask (F&P Simplus) to a nasal mask (F&P Eson), but forgot to change the mask setting on my A10 Autoset.
I had the best night's sleep since starting CPAP therapy 10 nights ago. AHI was 2.27, almost all of which comprised CAs.
My settings: 7-11 pressure, EPR off, ramp off.
I'm wondering what my failure to change the mask setting from FFM to nasal mask may have done to the therapy delivered to me by the A10? Did the A10 deliver higher pressure to me than it would have if I had set it to "nasal mask"? If so, does that imply that I should increase the A10's pressure setting from 7-11 to something like 8-12, if I also change the mask setting to nasal mask?
Or is one night's data too limited to provide a basis for adjusting the pressure?

ResMed claims the mask settings are to "optimize the airflow." Whatever that means. I've experimented by switching to pillows, nasal, full face with the same mask and didn't notice any conclusive results. Earlier in the thread they talk about calculating leak rate.
The problem with making too many changes at once is you don't know which change actually worked. Suggest run at the settings you have now, with the right mask setting, for about a week and see what the results are. If you do make additional changes, say to your pressure, change only one of the settings. Minimum or maximum but not both at the same time.
Didn't you recently turn off EPR? That probably had more to do with your results than mask type.

I wanted to learn Binary so I enrolled in Binary 101. I seemed to have missed the first four courses.
Alan -- a sensible suggestion, which I will implement. And yes, two nights ago I reduced EPR from 2 to 0.
Time to relax and give things time to settle down.
