[Treatment] Treating UARS with CPAP and bilevel
#71
RE: UARS and APAP
Thinking some more, I think I'll take path 2.

Back off to PS 4, and increase by 0.2 only after I have, say, three days in a row of good sleep (without those prominent wake ups you see in the second screenshot), until I get to 6, and then (if I get there), stabilize for a longer period.

RE: UARS and APAP
Good idea. I also found PS 4 was a bit aggressive for my needs and while the CA events were not that disruptive, a setting of 3.6 ended up being better. This kind of self-advocacy and thinking through problems reflects your arrival to graduation Smile

RE: UARS and APAP
Hi, Slowriter
Your case and quest  look very interesting to me; It appears similar to mine. My main curiosity this moment is why you are having so many arousals/awakenings; have to confirm this though. Then, I was wondering If you could repost your Sept, 2th (good night sleep as said) and some 5 ten-minutes windows (running FR contrasts), with the following curves and scales, top > downward, If you don't mind: pressures; FR (-120 to 120), FL (compressed), Tidal Volume (max 1000, with the median reference line; essential!), and leak.
Thanks

You and me both; the big mystery still!

Attached.

Keep in mind "good" is relative at this point. On this night, I made it through the night without obvious arousal, but that doesn't mean I felt rested next day.

But last night, with PS 4, no such luck; not a good night.

I think I misunderstood your request on the "windows;" let me know if you need more.

Oops; also initially made a mistake on the daily overview, so removed it. Corrected here, but as you'll see, very low FLs at this point.

RE: UARS and APAP
Ok, things start become more clear: very large number of arousals/awakenings, preventing proper sleep phase transtions; very low sleep efficiency......no way to be rested. It appears majority of them associated, following closely, flow restrictions (non-flagged) episodes. Still would need see 10min-duration windows to go furhter on possible interpretations, particularly running/embracing contrasts in FR/TV.
Did you have PLM's from your lab studies?

Thanks

Here's a few at 10 minutes.

PLM index was 0.9.

PLM was negative (as in, they noted no evidence of it).

By the way, the central apnea in your second picture is not a real one. Just look at the tidal volume. You took a couple of deep breaths and you waited before inhaling again which is perfectly normal. Actually, you did not have a central apnea event, you woke up. The fact that the breaths are really straight with no pause between the inhalation and the exhalation confirms that it's likely an arousal and not a central apnea.

RE: UARS and APAP
BTW, the one thing I now only vaguely remember, came in a conversation with the tech, after the titration study, so as I waking up, and not remembering details.

I think I may have been asking about the arousals, and I think she mentioned something like possibly I had "REM leakage"?

As I say, I don't remember the term for sure, and I don't see anything like this on the AB wiki acronym list. But does turn up on google, though not enough for me to be clear what that is.

I haven't seen the formal report yet.

For comparison, attaching overall view at PS 6,
