Label
Respiratory Event Index (Supine): (All respiratory events with at least 50% flow reduction and without any oxygen desaturation threshold used) / hours of estimated sleep in supine position from type III home sleep apnea test
Description

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)

Details about how the respiratory events were scored can be found in the Embletta scoring manual.
