You might try lowering your maximum pressure from 20 to 15 CM H2O and see how that gose for you.
Good luck to you, let us know of your progress.

A-Flex settings of 1, 2 and 3 all add 2 cmH2O of pressure relief during exhalation, plus each setting adds a different amount of additional "Flow based" pressure relief at the start of exhalation based on the how hard we are are exhaling. So there is a big difference between OFF and the lowest setting 1.
A-Flex settings of 1, 2 and 3 differ in how much additional Flow based pressure relief is added while we are actively exhaling.
A-Flex settings of 1, 2 and 3 also differ in how early the pressure starts dropping toward the end of inhalation as we are trying to finish up the last portion of our inhalation.
When A-Flex is 3, the pressure starts dropping the earliest, well before we have finished inhaling. I hear this can take some getting used to.
Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment. The Advisory Member group provides advice and suggestions to Apnea Board administrators and staff on matters concerning Apnea Board operation and administrative policies - not on matters concerning treatment for Sleep Apnea. I think it is now too late to change the name of the group but I think Voting Member group would perhaps have been a more descriptive name for the group.

When I turned off EPR, most of my CA's seemed to be converted to Hypopneas instead.

If anybody knows the A-Flex equivalent setting for my machine AirSense10 please let me know.
Is very attractive to cut in half mi AHI, but I don't have any idea what setting are you talking about.
I got down one complete unit in my AHI, because my Dr. eliminated my step in my machine and it goes from 4 to 12 cms in less than 5 minutes and keep there for ever. I was in 4 something AHI, now I am in 3 something (really nice), but I prefer to keep going down.
Tks in advance.
The Resmed equivalent function is called EPR and has a setting of 1 (least) to 3 (most) as well as Off.
I finally got around to checking in on all of the replies - Thank you all.
I will try gradually raising my lower pressure and drop my upper pressure back to ~15.
I wasn't trying to say that turning off 'A-flex' would work for lots of people, but more wondering what the drastic cut in AHI by turning it off means about my particular type sleep apnea. I do think the CO2 washout due to A-flex theory by Chill may be correct in lowering CAs. I do notice that I don't exhale as completely or easily with the A-flex off. By morning the resistance is not noticeable.
Surprising there aren't any intermediate settings between 'Flex 1' and 'Off'. There is not much difference in feeling between the Flex 1-3, but turning off does have a different (but not bad feeling).
I do not use ramp at all - settings below 8 have me starving for air, so 8 is just fine to start.
This result does not surprise me. Counter intuitively, I find many of the "comfort" features (ramp, EPR (A/C-Flex), heated humidification, etc) are often impediments to better control and actual comfort. Of course, YMMV.
