Percent of total sleep duration in REM sleep from type I polysomnography (full-night)

tmremp under Sleep Monitoring/Polysomnography/Sleep Architecture in HOMEPAP variables

Percentage of total sleep duration (i.e., total sleep time, TST) in REM from polysomnography

Percentage of total sleep duration in REM from type II polysomnography

tmremp under Sleep Monitoring/Polysomnography/Sleep Architecture in SOF variables

Percentage of REM sleep among total sleep duration from type I polysomnography

timeremp under Sleep Monitoring/Polysomnography/Sleep Architecture in CFS variables

Conventionally, total sleep duration would be called total sleep time (TST).

Percentage of total sleep duration in REM from type II polysomnography

timeremp under Sleep Monitoring/Polysomnography/Sleep Architecture in SHHS variables

The ratio of time in rapid eye movement sleep (REM) to total sleep time, expressed as a percentage.

Average oxygen saturation in sleep from type I polysomnography

Percentage of REM sleep among total sleep duration from type I polysomnography

timeremp under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables

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
