RE: New to Apnea Board & Sleepyhead, would you review screenshot please?
Dropped the pressure to 10-14 last night - screenshot is attached. Is one day enough to establish a baseline, or should I leave it at 10-14 for a couple more days before I start tweaking?
I sincerely appreciate the help from everyone who has responded, and Sleeprider in particular for the patience he has shown. In general I am a competent, intelligent person, but this sleep stuff doesn't match my strengths and I'm floundering badly.

RE: New to Apnea Board & Sleepyhead, would you review screenshot please?
Dropping pressure to 10-14 cm increased obstructive apnea from 1.3 at 19 cm to 2.48 and increased hypopnea from .95 to 3.41. So the idea that OA will respond to lower EPAP pressure may not work out. So the lower pressure approximately doubled OA and tripled H events..
What this tells me is that your effective EPAP pressure may be at a higher pressure, however, the hypopnea can be treated in bilevel with pressure support. With a bilevel titration you may end up with an EPAP pressure of 15 to 17, but I think the pressure support will address hypopnea in a way we cannot accomplish with your Dreamstation auto CPAP. I would suggest going for comfort, but low pressure is not going to achieve the lowest AHI with CPAP. You should request the Bilevel titration and prescription that should have been done in your last test. Even with the higher EPAP pressure, bilevel will end up feeling more comfortable than CPAP at your current high pressure of 19-20.
Your titration study did not indicate obstructive events at these pressures, so I still wonder if with Bilevel therapy whether the high pressure would be needed.
