Yet another new user needing advice!
RE: Yet another new user needing advice!
Have appt with sleep doc next week.
Wanted to check in and see if there is anything else to be done, and/or any issues anyone thinks I should bring up… 

It's been about 4 weeks.  I have tweaked pressures and have settled on 13-20, PS 4.2.  I have been using these settings for over 2 weeks now.

Overall I see a lot of  improvement!!

AHI was never a huge issue (usually 2-5), but the last 2 weeks has been consistently < 1, and I've had a couple of "perfect" nights (0.0 AHI).

Flow limits are virtually gone.

The pressure fluctuations are for the most part, gone too.  IPAP starts at 17.2, usually stays between 17.2-17.5.  It sometimes peaks a little higher, but I haven't been above 18 on these settings.

SpO2 drops continue, but the range is much tighter.
- Used to have Up-down ranging from 80-95%.  30-60 minutes < 90%

- Now rarely go below 87-88.  5-10 minutes or less < 90%.  No more headaches.

Biggest change is sleep time.  Before sleep was erratic(!!), and rarely for more than 90-120 minutes at a time.  Often getting up 3+ times a night to go to the bathroom or just walk around.  

Now I'm sleeping 3-4 hours at a time, usually only getting up once.  I even had one night where I slept 7 hours straight!

Fatigue continues, but it is better!  I've never had that great night of CPAP sleep where I woke up feeling like my life was "transformed".  Changes are more subtle -- I actually watched a movie with my wife without falling asleep.  Hoping for more improvement, but realize it takes time.

Here is an Oscar screen shot from last night.

I was wondering about the unusual curve at roughly 22:30-23:11, and again at 1:40-2:00.  I've seen it before in 20-40 minutes stretches.  A "tight" section of flow rate.   The other graphs -- tidal volumes, minute vent., respiratory rate, and even pulse and SpO2 are virtually flat.  Then at some point it returns to a more "normal" fluctuating curve/graph.  I zoomed in on the section @23:11 where the tight section ends.  The change in wave amplitude is pretty clear, but it may just be part of my sleep patterns.

Does it signify anything?  REM sleep maybe?

It signifies an arousal. The flat sections are solid sleep, a good thing. Don't obsess over it.

Not obsessing.  Learning!

Says something that a representation of "solid sleep" was a new thing… 

Thanks for the info!!
