Total Duration of Apnea and Hypopnea: Apneas with >= 1% oxygen desaturation + hypopneas with > 50% flow reduction and >= 1% oxygen desaturation during artifact-free estimated sleep from type IV home sleep apnea test
slpa51 under Sleep Monitoring/Polysomnography/Sleep Architecture in HCHS variables
Apnea and hypopnea events were not distinguished as separate event types during scoring. Both were classified as a respiratory event that required a 50% reduction in Nasal Flow signal for at least 10 seconds.
