Label

Arousal Index non-rapid eye movement sleep (NREM)

Description

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))]

Calculation
ai_nrem = 60*(arnrembp +arnremop) / (slpprdp - minremp)
Units
events per hour
