oximetry interpretation guide for sleepyhead
Is there a guide for understanding oximetry data in sleepyhead? Or what readings to expect in a sleep apnea patient.

Just my personal opinion. My posts are not medical advice or a statement of fact. Please consult a qualified physician or other qualified medical personnel. Please comply with all applicable laws, codes, regulations, and protocols.

I found this article, "Overnight Pulse Oximetry for Sleep-Disordered Breathing in Adults". Not specifically about SleppyHead, but if you scroll down it has some diagrams and how to interpret them.

The generally accepted threshold for SP02 is >/=88%. While it's also important to collect some baseline data when you are awake for comparison, any significant time intervals (several minutes) spent below this level are generally associated with the body not getting enough oxygen and thus being in a state of stress, interfering with sleep.

If during therapy you are still observing significant desaturation events below 88%, your setup might need to be tweaked, or in more extreme cases you might need supplemental oxygen.

Oximetry data can be especially telling when synced with your PAP detailed data - you can check for correlation of the desats with other metrics, in particular flow rate and the calling of AHI events (OA, H, and CA). I also "believe" that you can get a very rough idea of your sleep cycles, in particular REM periods, from your oximetry data. I confirmed my suspicion in a scholarly article I found once, though I haven't been able to locate it again. If I find it, I'll update this post with a link.
