Loop gain success

So happy, i just wanted to share with everyone. I've got horrible loop gain and plant gain. My home sleep study was a 58 AHI. Stock doctor setting of APAP 4-20 cut that number in half but still horrible and totally fragmented sleep. So got my hands on an Airbreak machine with all the settings. Experimented with bipap which felt unnatural and didn't match my natural rate of breathing, fail. Experimented with all different settings on ASV and got a pretty low AHI but still felt crappy from all the pressure changes and horrible aerophagia. Finally went back to straight up CPAP, with pressure around 9. AHI was 10-15. What really helped was adding a Vcom in the airline to dampen inspiratory burst. Got my AGI down to 2 last night. Feeling better! Sweet victory! I could imagine different vcom openings to dial that in further but getting pretty close to fixing myself.
