Respiratory Event Index (Non-Supine): (Apneas with no oxygen desaturation threshold used + hypopneas with > 50% flow reduction and no oxygen desaturation threshold used) / hours of artifact-free estimated sleep in non-supine position from type IV home sleep apnea test
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. Please refer to :slpa32: for the valid estimated sleep duration used to calculate this index. |
