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.
