Apnea-Hypopnea Index (REM): (Apneas with >= 4% oxygen desaturation and with or without arousal+ hypopneas with > 30% flow reduction and >= 4% oxygen desaturation and with or without arousal) / hour of REM sleep from type I polysomnography

rdirem4p under Sleep Monitoring/Polysomnography/Apnea-Hypopnea Indices in CFS variables

Calculated - Summary metric of sleep disordered breathing events. The definition of hypopnea events is consistent with the following clinical guidelines: (1) AASM 2012 update (recommended) Berry RB et al. 2012 (PubMed ID:23066376), and (2) AASM 2015 (acceptable) [Berry RB et al. The AASM Manual for the Scoring of Sleep and Associated Events: Rules, Terminology and Technical Specifications, Version 2.2. American Academy of Sleep Medicine, Darien, IL, 2015.]. Search for all AHI variables consistent with the same clinical guidelines within this dataset

Calculated - RDI (>= 4% desaturation)
