If you had to take a break from CPAP after the night with the mask liner, because of acid, and today (after almost all night at 9) the acid is returning then I don't think raising the min to 9 is a good idea just now. because if possible, we don't want to irritate that stomach sphincter.ejbpesca wrote: ↑Sat Oct 08, 2022 9:33 amWaking 10/6: No aerophagia.

I took a break from the CPAP the night before. Had the first acid free day in a very long time. I was extremely tired all day with no CPAP. Today I do not feel well rested and here comes the acid, but no aerophagia.
The night before the break, your median pressure was lower - and yet you needed that break.
If we agree that 9 isn't cutting it - as max - and some night(s) you have events snores and flow limitations driving your pressure to the max, but some nights less, but still have acid reflux then I would be more conservative about upping the min, in the hope you may have some relief from the pressure when your breathing is better, and the pressure drops. But I would try upping the max - slowly and carefully.
Try to look at your data and track median pressure and its relation not only to your AHI, but also to your acid reflux.
Also think about the EPR.
With your EPR at 2, your effective EPAP (Exhale Positive Airway Pressure) last night (and during your obstructive clusters) is 7.
What happens to you if you turn EPR off? Or drop it to 1? It's a way of raising the minimum pressure when you exhale and maybe make obstructions less likely.
I realise that's counter to what a bi level does, but then, we're not even close to where your minimum EPAP pressure handles obstructions, let alone near your necessary maximum.
Basically, EPR subtracts 1 or 2 or 3 from the exhale pressure from whatever minimum pressure you've defined.
