Scoring stage2/ deep sleep unreliable

stg2stg3pr under Sleep Monitoring/Polysomnography/Signal Quality in CHAT variables

1=sleep staging problem - scoring stage2/stage3-4 unreliable (when distinction between Stage 2 and Deep Sleep is unreliable because of EEG artifact (usually due to the respiratory or sweat artifact on the EEG, and High Pass filter =1Hz used))
