Apnea load (total duration of apnoea events) and hypopnoea load (total duration of hypopnoea events) correlate better with the Epworth Sleepiness Scale (ESS), compared to the traditional Apnoea-Hypopnoea Index (AHI). (https://pubmed.ncbi.nlm.nih.gov/30019066/) Study Summary: “Apnoeic and Hypopnoeic Load in Obstructive Sleep Apnoea: Correlation with Epworth Sleepiness Scale” (https://pubmed.ncbi.nlm.nih.gov/30019066/) Objective: […]

The apnea–hypopnea index (AHI) is commonly used to diagnose obstructive sleep apnea (OSA), but it doesn’t fully capture physiological variations that may contribute to health risks. Respiratory event duration, which reflects arousal threshold, may be a more precise predictor of mortality. The studies have categorized […]
