@Gideon thanks for your brief expert comments, and perhaps you can cut my learning curve further:
1) In other threads forum experts seem to want the 95% Flow Limit stat to be at or below 0.10, preferably 0.03 or below, BUT if I understand your comment with ASV I can mostly ignore Flow Limits? What FL type of stat or pattern/trend if any would be a concern?
2) While I mostly have substantially improved Large Leaks since beginning to address this Aug. 8th there are still nights (or sub-session within a night) with LL > 15%.
I believe I had read that Large Leaks can distort the validity of AHI and other stats, is that true? What % of large leaks should be a concern? While many consecutive nights they are <3% or even zero and while one of my goals is to keep them very low, given the vagaries of mask and my mouth taping and interactions with side sleep position and pillow (even though I am not that active in my sleep) I don't expect that I will be able to eliminate virtually all of them. At sleep dr recommendation for a while I am changing nasal cushion # 10 days for a while so that an "old and worn" cushion is not a factor in what might be leading to leaks.
3) While subjectively I am feeling a good deal better (more energy, less desire or actually taking brief afternoon nap) I still feel there might be room for improvement and health benefits. Any data category that I might monitor and look toward improving (or if already good, keeping constant)?
Separately but related I have begun to use Wellue O2 ring and while too soon to say, so far ODI seems to be OK but too much variation in my few data nights.
I am also addressing the very dry mouth that I get with CPAP and have separate thread about that as while it is aspect of my treatment side effects it does not seem related to data and possible machine setting changes that I reserve for this thread.
=======
I note that in my comment #75 point 2 above, I alerted moderators that I had inappropriately started another thread on treatment and upon reading forum guidelines to keep most everything in one thread and moved that info to this thread and suggested the other superfluous thread be deleted. As of this comment that other thread has not been deleted.
Thanks for your (or anyone else's) assistance.
