1=Problems with respiratory events (when due to the technical quality of the respiratory signals, distinctions between hypopneas and normal breaths are equivocal in over 20 % of scored events; also when the quality of the oximetry signal raises doubts about actual magnitude of desaturation linked with over 20 % of respiratory events (unstable baseline)

Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater).

Calculated - Summary metric of sleep disordered breathing events. 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)The definition of hypopnea events is consistent with the following clinical guidelines: (1) AASM 2012 update (alternative) Berry RB et al. 2012 (PubMed ID:23066376), and (2) AASM 2015 (acceptable) [Berry RB et al.
