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?

- rootusrootus 2y agoThe 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.
- NelsonMinar 2y agooh 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.)
