IIRC 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.
