Total Duration of Apnea and Hypopnea (Supine): Apneas with >= 3% oxygen desaturation + hypopneas with > 50% flow reduction and >= 3% oxygen desaturation during sleep in supine position from type IV home sleep apnea test
Total Duration of Apnea and Hypopnea (Supine): Apneas with >= 3% oxygen desaturation + hypopneas with > 50% flow reduction and >= 3% oxygen desaturation during sleep in supine position from type IV home sleep apnea test

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.
