Heart rate jumps during sleep w/o waking/activity

Some of those look low to me. Are you showing hypopneas? Even restrictions of flow that don't actually awaken you, at least as you remember them, DO cause arousals. Each arousal disrupts the series of sleep stages one takes, meaning you might start all over again. The typical person experiences REM, for example, approximately three (3) times during the first six hours of sleep. Six hours is pretty stingy all by itself, but a single arousal during those six hours might lose you one of the three typical REM cycles. That's a chunk...again...if sleep longer than six hours is fleeting for you. It is for me...I often get less than six, but my low AHI and solid treatment with my fixed pressure of 8.0 means I never fail to get the three stages completed. As a result, I function well, and never have to nap. Nor do I tend to lose focus, drift off, nod off, etc.
I wonder if you sometimes awaken on your back.

I haven't replied lately because I'm seeing a lot of inconsistencies in the CPAP data/results.
First, I'm pretty much required to sleep on my back because sleeping on my sides causes a lot of pain in back, hips, shoulders and ribs. So I use a soft cervical collar to minimize chin-tucking and a relatively high pressure to handle the events.
I'm actually seeing much higher events and AHIs when I sleep on my sides, which I do when the back pain gets too harsh - generally about 5-6 hours into a sleep.
I'm tempted to try a double sleep strategy - 5-6 hours at overnight and an afternoon nap of 1-2 hours simply to bypass the issue with back pain
I do see a small, variable number of hyponeas and a higher number of CAs which seem to have a correlation with movement/sleeping on the side.
The original problem of much higher pulse rates appears to have gone away.
I occasionally see a pattern where there appears to be a sleep cycle minus the deep sleep, but those are nights where the pain is relatively low. Seems the more I move, the worse the pain and the effects on sleep.
Right now, I'm working toward getting some consistency in the sleep data - last week was a low of 1.87 and a high of 6.96 - including a night where one 6 hr period was 1.41 (mostly on back) and the rest of the night was 16.9 (mostly on side).
