Label
Apnea-Hypopnea Index: (Apneas with no oxygen desaturation threshold used + hypopneas with > 50% flow reduction and >= 3% oxygen desaturation) / hours of estimated sleep from type III home sleep apnea test
Description
Calculated - Summary metric of sleep disordered breathing events from the baseline screening visit.
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)
There is a HeartBEAT specific respiratory event index measure aphypi. Details can be found in the Embletta scoring manual.
