Will Apple Watch Series 7 measure & report periodic oxygen levels while sleeping? It does during the day

Hello drbobdr,
Thanks for getting back to us with those additional details. It looks like you're still unable to measure blood oxygen during sleep. We'd be happy to look into this with you.
Which iPhone model, and iOS version are you using with your Apple Watch? Settings > General > about.
"About background measurements
The Blood Oxygen app on your Apple Watch will occasionally measure your blood oxygen levels if background measurements are on. This will usually happen when you are not moving. Depending on how active you are, the number of readings collected each day and the time between these readings will vary. Blood oxygen measurements use a bright red light that shines against your wrist, so it may be more visible in dark environments. If you find the light distracting, you can turn off background measurements.
Blood oxygen measurements only occur during sleep if the Track Sleep with Apple Watch setting is turned on."

Thank you for using Apple Support Communities. Have a nice day.
Thank you. I did that… but it still doesn’t measure during sleep. It measures respiratory rate but no oxygen level. Appreciate your response.
IPhone 13 Pro Max with iOS 15.1
Apple Watch 7 with Watch OS 8.1
All settings for sleep on per instructions.
Reading periodically during the day’s activity. Reading other parameters during sleep. Not reading Oxygen level periodically during sleep.
Is it supposed to?
Thank you. It appears arm must be in proper position to measure properly. Watch face up. Thanks all.
