The SpO2 data isn't useful for detecting sleep apnea because the sampling frequency on a smartwatch is way too coarse to pick up on it.

oh that's too bad. The O2Ring samples every 2 or 4 seconds but a lot of cheaper devices take an average reading once a minute or so which definitely obscures sleep apnea. (normal adults take a breath every 3-5 seconds when sleeping. with obstructive sleep apnea that can be more like once a minute.)
