Total Number of Apneas and Hypopneas (Supine): Apneas with no oxygen desaturation threshold used + hypopneas with > 50% flow reduction and no oxygen desaturation threshold used during artifact-free estimated sleep in supine position from type IV home sleep apnea test
Description

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.

Estimated sleep duration, providing an approximation of total sleep duration (i.e. total sleep time) inferred from analysis of non-EEG channels Zhao et al., 2017 (PMID:27707441) Any continuous periods of >=20 min with loss of respiratory channel was marked as wake and not included in the estimates.
