Sleep Efficiency (full-night): the ratio of sleep duration (i.e. total sleep time) to in-bed period from type I polysomnography
slpeffp under Sleep Monitoring/Polysomnography/Sleep Architecture in HOMEPAP variables
Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep (i.e. total sleep time, TST), while in-bed period is the interval between lights off/in-bed time and lights on/out-bed time (i.e. time in bed, TIB).
Total sleep duration from type I polysomnography (split-night, diagnostic)
slpprd_d under Sleep Monitoring/Polysomnography/Sleep Architecture in HOMEPAP variables
Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep, conventionally called total sleep time.This time period is used to calculate indices and other averages.
Total sleep duration from type I polysomnography (split-night, treatment)
slpprd_t under Sleep Monitoring/Polysomnography/Sleep Architecture in HOMEPAP variables
Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep, conventionally called total sleep time.This time period is used to calculate indices and other averages.
