It’s only turned off in the US right? Would they use the data in the rest of the world since SpO2 data is available there?

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.)
