srwilsn3's therapy thread | APAP -> BiPAP

SR: I see them now. I will set up a night camera and see if I can't get to the bottom of what I'm doing.

It may be nothing at all, but it could be a good project for a behavioral scientist...I do know the tedious hours of observation you guys are known for.

The following graph shows normal breathing going into distorted wave shapes resulting in a Pulse Change. If you look at the Events Flag area, the only flag in the zoomed area is Pulse Change (PC)  from my Wellue Pulse/Oximeter. I started coming up with 0.00 AHI reports, the only thing left to chase on the events graph was PC & SD (SpO2 Drops).  


   

Your Double CA  showed some distorted wave shapes afterwards. From your spike in leak rate I suspect you held your breath, shifted position, your mask  re-adjusted therefore the leak spike and leak rate settling at a lower rate after that, the following Flow Rate wave shapes would suggest a possible Upper Airway Restriction.

When I have a double CA  of 24 seconds duration it will drop my SpO2 below 80% to the 70% range, Yours was ~40 second duration, my O2 would have pegged at 70% SpO2. That is the lowest my Pulse/Oximeter will report.

But then again I'm a sensitive type of person.

We each have our own reasons for using *Pap.

Thanks all. I haven't done any follow up except for changing the trigger to Very High yet. Plan is still to observe my sleep with a night camera soon. That said, my CAs have been eliminated the last 3 nights. Subjective restedness is slightly improved.

UR, I am learning I am quite, quite sensitive as well.

I don't know what this board's stance on UARS is, but I am becoming quite convinced it's a separate (or at least cognate) pathology from OSA that is characterized, in part, by a low arousal threshold.

Dr. Steven Parks has some YT videos and podcasts of interest, he likes to sell books & stuff, as a behavioral scientist you might find his approach to sleep hygiene a logical approach to doing all that we can to prepare for a restful night of sleep.

Dr. Barry Krakow is interesting.You can google some of his YT videos and podcasts.
