Sleep Heart Health Study
The Sleep Heart Health Study (SHHS) is a multi-center cohort study implemented by the National Heart Lung & Blood Institute to determine the cardiovascular and other consequences of sleep-disordered breathing.
ai_rem under Sleep/Polysomnography (PSG)/Arousals in CHAT
Rapid eye movement sleep (REM) Arousal Index - total arousals in rapid eye movement sleep (REM) per hours of rapid eye movement sleep (REM) (Total number of arousals in rapid eye movement sleep (REM)) / (hours of rapid eye movement sleep (REM))
ai_nrem under Sleep/Polysomnography (PSG)/Arousals in CHAT
Non-rapid eye movement sleep (NREM) Arousal Index - total arousals in non-rapid eye movement sleep (NREM) per hours of non-rapid eye movement sleep (NREM) [(Total number of arousals in non-rapid eye movement sleep (NREM)) / (hours of non-rapid eye movement sleep (NREM))]
remnrempr under Sleep/Polysomnography (PSG)/Sleep Architecture in CHAT
1=Sleep staging problem - scoring rapid eye movement sleep (REM)/non-rapid eye movement sleep (NREM) unreliable (when identification of Stage rapid eye movement sleep (REM) is unreliable (usually due to poor or missing EMG or when both EOGs are absent))
ai_rem under Measurements/Polysomnography/Arousals in SHHS
Rapid eye movement sleep (REM) Arousal Index - total arousals in Rapid eye movement sleep (REM) per hours of Rapid eye movement sleep (REM)

Scorer noted that there was a problem differentiating rapid eye movement sleep (REM) and non-rapid eye movement sleep (NREM).
