Was I not asleep under anesthesia?

[nikotgi]

I had a medical procedure yesterday. I was under monitored anesthesia (propofol and on oxygen) for about 45 minutes. When I reviewed my sleep data today, there was no sleep recorded for that time. I know I was asleep and dreaming, though. How is this possible?

Welcome to the Fitbit community, @nikotgi!

What you've experienced is how accurate Fitbit's sleep tracking is. Anesthesia displays a more widespread disruption of brain connectivity compared with natural sleep, so it is not a state of sleep.

@nikotgi   Everything that @Talahthas wrote about anesthesia being different from sleep is true.  Fitbit's main trigger for sleep is lack of arm movement.  However, the minimum amount of time to trigger sleep is one hour.  The minimum sleep time for sleep stages is three hours.

As @LZeeW points out, the key to your answer is that your sleep period was under an hour. 

@vikramka and @nikotgi You could manually mark the period as sleep
