Here are a few shots from last night. The flow does appear to be normal now...at least to me. Now I just need to get rid of the obstructives. I guess bump up the epap a little? The clutter at the beginning I wasn't even asleep yet so I don't know about all that. If we get into that kind of discussion I probably should bounce back to my therapy thread though I guess.
I just noticed I did a lot of guessing in what I said above.

The CA at the beginning of the sleep sessions might be a SWJ (Sleep Wake Junk) issue. Another thing that may be adding to the CA, it appears in the pressure chart to have a Ramp pattern to it that's present at each segment start, where these CA reside.

I feel Dave is right here, since he doesn't have the benefit of having a close up view of the events in question. The first part maybe SWJ but deeper in could easily be somewhat normal sleep, but apparently unlike you I lack the ability to clearly identify sleep state from an all night view.

I can definitely get you a zoomed view once I get back home. I know the cluster at the beginning was while I was awake adjusting/fiddling with the mask. Then the little gap was a trip to the bathroom.

How long are those centrals when you thought that you were awake? I've tried to deliberately create apneas while awake to try to figure out what the various wave forms feel like when I'm conscious. What I can say is that ten seconds holding my breath feels like a really long time to me when I'm awake. I believe that once the apnea gets into the 20-30-40 second range I have to be asleep to let that happen.

RE: Breath pattern question
If you want to experiment with central apnea length you have to create the milieu in which they occur. If you suddenly try to hold your breath, your body was looking for a breath at ~5 seconds so at 10 you're already sucking (or need to suck) wind. If you take 5 or 6 huge breaths you've dropped blood CO2, plus lung reserve CO2, then you have to add circulatory time lung > breathing receptors so a 25 -30 second apnea is easy (and required). A single sigh will get you a shorty.
Sleep-onset centrals are a little different. The CO2 threshold changes at sleep-onset, so you're not going to see a lot of these. Like one.
Difficulty in taking sleep will net you a variety pack. Add in some motion artifact, and there's SWJ.
