CPAP with Fitbit Out of Whack!!

Good Morning:

I have recently started on the CPAP and am still adjusting to it. Prior to the CPAP, I monitored my sleep using my Fitbit and it would show my benchmarks between light sleep, deep sleep, REM sleep and awake were all in the appropriate zones (right amount of time for each zone) during the night.

Now, with the CPAP, the amount of time I am in each zone is WAY off. Over 80% of my sleep is in the Light Sleep zone and I'm getting very little REM or Deep Sleep.

Has anyone else experienced this or know why I'm not getting into the Deep or REM sleep. I'm wondering if this is why I'm still feeling very tired when I wake up.

Thanks

I've never used a Fitbit, so can only speculate. My thoughts would be that you are not totally settled with the CPAP and mask, and that in turn is changing your sleep patterns. It does take some time.

The best way to figure out what the CPAP is doing is by downloading SleepyHead and viewing your detailed data with it. It is free software and needs a PC or Mac, and a SD card reader to use it. Your CPAP also has to be compatible with the software. Here is a basic instruction manual so you can see what it could do. It may uncover opportunities to improve your machine setup and will report on mask leakage issues which also may be disturbing your sleep.

Suggest you get a copy of your sleep study and see what the study had to say. It is VERY likely a better measure of which sleep state you slept in and for how long during the study. Compare that to your "fitbit" and see if the gizmo track sleep in a similar manner as your study or not. I suspect the fitbit isn't a great sleep state monitor but just guessing.

A Fitbit is not a reliable method of monitoring sleep. It certainly has no way of knowing which stage of sleep you are in.
