RE: UARS and APAP
Keep in mind, I'm only trying to identify where to look on the video.

RE: UARS and APAP
maybe working from flow rate to video is a quicker way? if you don't want to go through the entire video (can it be fast forwarded to view more quickly?), scroll through your flow rate at say a 6 or 7 minute view scale. that should only take a few minutes. then check the video against anything you see in the flow rate that looks like plm or any other anomaly. one of these days I want to get a camera because there are a lot of odd things in my flow whose sources I suspect but can't can't identify for sure. you may or may not not see plm and if you haven't learned everything there is to know about flow rates yet (I sure haven't) you might learn more about what causes different looking flow curves in your charts.

That's basically what I did here :-).

What one has to be in mind is that PLMS has different degree of  manifestations of and consequences. Hope you realize soon what would be consequences in your case, once confirmed; It maybe significant or not, as discussed in literature.
Good luck

RE: UARS and APAP
I saw your post with the helpful video examples.

I think the movements I see with mine are similar to the Level 1 example.

I don't really see a lot of it though; again, so far.

I'll check again and try to get a handle on the timing question.

PS - you should really use the forum quote facility. Not only is it more consistent for sighted readers; also would actually work for people with visual impairments using screen readers.

RE: UARS and APAP
This is kind of interesting to me.

I made two minor changes a few nights ago.

I dropped PS from 6 to 5.2, and raised min EPAP from 6 to 6.2.

I also changed trigger from high to very high.

AHI instantly dropped from 3-5 (where it had been for awhile, even with trying different PS values) to below 1, and last night was 0!

..It may happens! anyway it looks your AHI is too low to care about, maybe....

_by the way, it appears your architeture (including REM, less awakenings) is getting much better! ....started any medication?
Good luck

I've been experimenting for past couple of months with various supplements that calm down the nervous system/raise the arousal threshold.

The significant drop in AHI was independent of those, but the good night last corresponded with stopping valerian (seemed to mess up sleep onset for me) and returning to my original cocktail of GABA, 5-HTP, L-theanine.

I did also get a prescription for eszopiclone, but I haven't picked it up yet. I may or may not use it; or maybe only on nights where I must sleep soundly (for professional reasons).

RE: UARS and APAP
Yes, indeed, I read this recently....

Clin Sci (Lond). 2011 Jun;120(12):505-14. doi: 10.1042/CS20100588.
Eszopiclone increases the respiratory arousal threshold and lowers the apnoea/hypopnoea index in obstructive sleep apnoea patients with a low arousal threshold.

RE: UARS and APAP
Yes, I saw the same study!

I did want to mention this, though, because elsewhere on the forum (have lost track of where), I came across someone saying the trigger setting seemed to correlate with CA events, and that having it on very high seemed to eliminate them.

Not sure if that's what accounts for the change I saw, since I simultaneously changed pressure, but it's probably worth experimenting with.
