nsrr_ahi_hp3r_aasm07 Apnea-Hypopnea Index : (All apneas + hypopneas with >=50% nasal cannula [or alternative sensor] reduction and >= 3% oxygen desaturation or with arousal) / hour of sleep

Harmonized by the NSRR team.

The definition of hypopnea events is consistent with the American Academy of Sleep Medicine (AASM) 2007 Manual (pediatric). [Iber C et al. The AASM manual for the scoring of sleep and associated events: rules, terminology and technical specifications. Vol. 1. Westchester, IL: American Academy of Sleep Medicine, 2007]

slpprdp Total Sleep Duration: the interval between sleep onset time and lights on/out-bed time while the participant is asleep from type I polysomnography

Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater).
