setting min and max the same on apap instead of turning the machine to cpap mode? what's the reasoning for that?
my plan (so i don't abuse the support you're providing me):
- set 11.6 min 11.6 max w/ 3 epr. if dealing with obstructive/hypopnea/rera, increase pressure slowly until those are eliminated
- if i'm dealing with more centrals because of pressure increase, i'll try reducing epr (i read on the optimizing therapy page that reducing epr could help reduce centrals)
- if i experience more flow limitations with reduced epr, or if i can't tolerate the pressure without epr, i'll have to find a middle ground somewhere and/or wait for my septoplasty surgery and potentially explore getting a mandibular device for additional support.

Some of the Autoset machines do not report flow limits in CPAP mode, so using APAP mode with fixed pressure is a work-around. Otherwise, should not make a difference. I was one of the authors on the Optimizing Therapy wiki, and yes, we often reduce EPR, especially when 95th percentile flow limits are low, or zero as in your case. I should have been paying attention.

oh interesting. past data when i was in cpap mode shows that my airsense 11 is still measuring flow limits. i have so much more understanding now in how to slowly experiment. i'll report back if i either have perfected my settings or if i run into any roadblocks. your guidance has been very great and so has been the optimizing therapy page you helped write.

so it seems pressure 14 epr 2 can give me 1 really good night! except i have a stomach ache from swallowing some air last night. bleh.

14/12 pressure resolves the AHI, but you may have to compromise therapy for sleep disordered breathing to find a tolerable pressure for your aerophagia. Only you can really find that sweet spot by titrating downward until you find the situation you can live with.
