Is the FitBit accurate if I have Central Sleep Apnea?

[pg3t]

The FitBit is indicating I get low REM, but I seem to dream a fair amount. I also have RBD events about once a month. I don't take any medication since my RBD events are rarely anything more than vocalizing or a little leg movement.

@pg3t   In answer to your first question, Fitbit doesn't have any current way to monitor either central or obstructive sleep apnea.  In answer to your second question, I am not an expert on sleep disorders.  My internet search tells me that RBD is a sleep disorder where people move during dreaming. Fitbit's Help article on sleep stages makes it sound like the sleep stage algorithm depends on the "not moving" part of REM sleep to put you in REM stage sleep.  Everything I read suggests that a Fitbit will underestimate your REM sleep.

I think you should talk with you doctor if you have other concerns.

That makes sense! Thanks!

This is an old post so I doubt you'll read this but my Sense 2 has difficulty detecting my sleep and I have mixed central and obstructive.  Last night it recorded no sleep at all but I was in bed 8 hours and I'm sure part of it was sorta sleepy but it gave me a zero.  Admittedly, I usually sleep 3 - 4 hours but not zero.

Hello @dking72315 

As you noted, this is a very old thread.

You might have better luck getting a response by posting your question in the Sense 2 product help forum (<-- click link)
