I'm not an qualified expert, but I spend a lot of time reading about and using this stuff and I'm extremely skeptical sleep apnea detection is very accurate without the pulse oximeter functionality.
But gosh, I hope this is accurate across the Watch's wide user base.
I wouldn't say it's likely, but I do wonder if the pulse oximeter is being used surreptitiously. In any case, if you could use the pulse oximeter, this functionality would immediately become much more powerful.
- rootusrootus 2y agoIIRC the pulse oximeter isn't all that useful for sleep apnea detection anyway, because on the watch it does not run continuously. Just takes measurements every X minutes. I think the oxygen level drop happens on a short enough timescale that you need the continuous monitoring to pick up on it.
- runjake 2y agoI think the pulse oximeter would be most helpful in concert with the accelerometer, as described in the article.
- TechDebtDevin 2y agoWatch Sp02 detection is usually at rather long intervals to conserve battery and typically have not resulted in any sort of detection of low 02 (in my experience, I have very bad sleep apnea)compared to a pretty dependable and accurate $30 on the finger oximeter.
- lathiat 2y agoThe watch can ramp the detection up for periods of time if it chooses, such as when doing a workout. But also, people with sleep apnoea tend to have their O2 trend low not just go briefly low.
- m463 2y ago> sleep apnea detection I don't think it has to be as accurate as other things like blood glucose levels, because with those people might use the results to inject insulin. Detecting sleep apnea might be more like afib detection. It just tells someone they should be checked out.
