Apnea-Hypopnea Index: (All apneas with no oxygen desaturation threshold used and with or without arousal + hypopneas with > 30% flow reduction and with >= 3% oxygen desaturation or with arousal) / hour of sleep from type I polysomnography

Apnea-Hypopnea Index: (All apneas with no oxygen desaturation threshold used and with or without arousal + hypopneas with > 30% flow reduction and with >= 3% oxygen desaturation or with arousal) / hour of sleep from type I polysomnography
The definition for hypopneas is consistent with the following clinical guidelines: (1) American Academy of Sleep Medicine (AASM) 2007 Manual (2012 update) (recommended). Berry RB et al. 2012 (PubMed ID:23066376), and (2) American Academy of Sleep Medicine (AASM) 2015 (recommended) [Berry RB et al. The AASM Manual for the Scoring of Sleep and Associated Events: Rules, Terminology and Technical Specifications, Version 2.2. American Academy of Sleep Medicine, Darien, IL, 2015.] |

Sleep Efficiency: the ratio of sleep duration (i.e., total sleep time) to in-bed period (i.e., time in bed) from type I polysomnography
|
Sleep Efficiency: the ratio of sleep duration (i.e., total sleep time) to in-bed period (i.e., time in bed) from type I polysomnography
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). Percentage of time in bed that was spent sleeping, or the ratio of total sleep time to total time in bed, expressed as a percentage. |

tst
Total sleep duration from type I polysomnography
|
Total sleep duration from type I polysomnography
Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep. Conventionally this variable would be called total sleep time (TST)(i.e. total time spent in stage 1 or greater). |
