Report Sleep Bouts

This tool reports statistics about Sleep bouts from Polysomnography (PSG) files.

Sleep bouts are defined as continuous periods of three sleep stage combinations :

  1. Continuous period of N2 and N3 stages

  2. Continuous period of N2, N3 and REM stages

  3. Continuous period of REM stage alone

To see the complete list of variables included in the report, see Sleep Bouts Report.
