Non-rapid eye movement sleep (NREM) Respiratory Disturbance Index (RDI) at all desaturations [(total number of apneas and hypopneas in non-rapid eye movement sleep (NREM)) / (hours of non-rapid eye movement sleep (NREM))]

Due to signal problems, scorer was unable to reliably assess arousals in stage rapid eye movement sleep (REM). The scoring of arousals in stage rapid eye movement sleep (REM) was determined to be unreliable.

Conventionally, total sleep duration would be called total sleep time (TST).Percent of sleep time in rapid eye movement sleep (REM) [100*(number of minutes scored as rapid eye movement sleep (REM)) / (Total Sleep Time (TST))] * 100
