The setting Rich is referring to is called EPR on your machine.
My guess is that with an unusually long sleep, your last hour was of very shallow sleep which produced a lot of sleep/wake junk as your brain drifted between barely asleep and barely awake. I tend to lay in bed like this on weekends and my AHI for the last hour is all over the map.
This appears to be an issue with me too. Always half awake/sleep. I am hoping for it to be pressure related. I am going to see Dr. tomorrow for ECG and Holter monitor. I too, do not think I have any heart issues but then again something is causing this. I am anxious to hear all the replies.
Thanks for the reassurance guys. It was kind of what Zi was thinking.
Last night I went to bed at 10, same a previous but this time woke at 4:30. AHI back down to 2.8.
When Ive seen these episodes (never as long as example posted) I always felt likely to be just "twilight" period of restlessness. Maybe just law of probability I should have one just before waking and so have higher average AHI.
Will review more data and see!
Kerp up the good work!

Had another couple of high AHI nights. Didn't panic but when I came to download data, noticed on one particularly high AHI night. When I checked data, AHI got as high as 30, all centrals and Sleepyhead reports period of Cheyne Stokes breathing! Googled this and scared the whatnot out of myself! Will send report to sleep doc but also thought I'd share on here. Its only happening occasionally, these flood of centrals late in my sleep, but this is first and so far only time of Cheyne Stokes.
What does this mean?
Discussing this with my partner on both recent "periods" of these high centrals, its been broadly aligned with having cold/cough. First time was at the end of a really nasty 2 week cold. This week I've very dry feeling chest and tickle cough though not bothersome. Could this be linked?
I really don't believe I have congestive heart failure. In first quarter of year had extensive cardiac tests, recently had chest CT scan which was clear. Also been exercising last couple of months and getting much fitter and lighter!
How long have you been taking Phenergan? Do you take it every night?
Do you experience the clear airway events only when you take this medication?
There may be some correlation between the meds and CA events. This is something to discuss with your sleep doctor.
I also wonder if you are rolling over on your back during the time you see the CA events?
