Apnea Hypopnea Index

The Apnea Hypopnea Index (AHI) is a measurement used to assess sleep disorder severity, specifically sleep apnea. It counts the average number of breathing interruptions (apneas) and partial blockages (hypopneas) occurring per hour of sleep. A lower AHI indicates fewer interruptions and better sleep quality, while a higher AHI suggests more frequent breathing problems during sleep. This index helps doctors diagnose sleep apnea severity, guiding treatment decisions to improve sleep and overall health.
