new user oxi report

Being new to this, appreciate any feedback. Someone mentioned concern that I had dips below 90 when sleeping, they seem few and short to me, some seem related to heart pulse when I get up in middle of the night. I see some black marks at top of graph, but oxi taped to finger and stays on all night. I'm a pretty calm sleeper, mostly on sides, no snoring. I am 70, female, have afib diagnosed a year ago, no symptoms now, only med is anticoagulant.

I fall asleep after about hour of TV. Heart rate normally 60's, at night pulse rate in 50's. Daytime oxi in mid-90s.

Also, can you tell rem sleep?

I think your data looks good.

There is no way to tell REM sleep using an oximeter, but to venture a guess the pattern changes a little. If you look at your 7/22 data I would guess that a deeper stage of sleep occurred at around 1 hour and 20 minutes and also just before you woke up.

Thank you both for your replies !
