Short-Term Variability in Apnea-Hypopnea Index during Extended Home Portable Monitoring
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4877318/ Study Objectives: Apnea-hypopnea index (AHI) is the primary measure used to confirm a diagnosis of obstructive sleep apnea (OSA). However, there may be significant night-to-night variability (NNV) in AHI, limiting the value of AHI in clinical decision-making related to OSA management. We examined short- term NNV in AHI and its predictors during home portable monitoring (PM).
Methods: Single center prospective observationa
