This is what I'm thinking, too. It's interesting that before CPAP I would not get these kind of sudden jolts. A slight kick of the leg or something as I'm falling asleep, yes, but I never popped up off the bed like a click beetle.
When I've had apnea arousals that make me fully wake up, it's been a different sensation. Those usually come on with an intense terror or nightmare that "slowly" builds (at least I perceive it that way) until I wake up and then feel hot/flushed with a rapid heartbeat.
I'm wondering if the machine is not playing well with my body. Here's what I believe is the arousal from this morning, based on the time:
That doesn't say much by itself, but what concerns me is that I have a whole lot of those kind of erratic flow curves each night and a lot of "flat lines" which don't get flagged as apnea events because they're too short.
My most "normal" flow curves look like this:
They're not the nicely rounded sine waves that I've seen elsewhere and seem to be slanted to the right. Half-way through the inhale there's a brief plateau before the characteristic bell curve.
I'd appreciate input on whether or not these look typical. My understanding is that an APAP should find just the right pressure to prevent any kind of flow limitations or labored breathing.
