STOP-BANG Score for Obstructive Sleep Apnea - MDCalc OSA (obstructive sleep apnea) is due to a mechanical obstruction of the upper airway resulting in diminished breathing (hypopnea = narrowing) or elimination of breathing (apnea = collapse and obliteration) The gold standard for OSA diagnosis is polysomnography
Apnea-Hypopnea Index (AHI) and Sleep Apnea - Sleep Foundation Doctors use AHI results from sleep studies to guide diagnosis and treatment decisions for sleep apnea An AHI of fewer than 5 events per hour is considered normal Mild sleep apnea is diagnosed with an AHI of 5 to 14, moderate with 15 to 29, and severe with 30 or more
Apnea-Hypopnea Index, Explained: What Your AHI Means AHI stands for apnea-hypopnea index, a measure used to diagnose sleep apnea and determine its severity Learn how AHI is calculated and what results may mean
How to Understand the Obstructive Sleep Apnea Severity Scale In order to understand severity, you need to understand how it’s defined The Apnea-Hypopnea Index (AHI), also known as your AHI score, objectively measures the number of respiratory events you average per hour of sleep during a home-based or lab-based sleep study
How to Read and Understand Sleep Apnea Test Results Understanding these key numbers prepares you to discuss your results confidently with your healthcare provider and take steps toward effective treatment The most revealing numbers quantify the frequency and impact of breathing interruptions during sleep
The Official STOP-Bang Questionnaire Website Chung F et al J Clin Sleep Med Sept 2014 If the STOP-Bang score is 3 vs 0-2, the risk of obstructive sleep apnea is 2 5 fold If the STOP-Bang score is 4 vs 0-2, the risk of obstructive sleep apnea is 3 fold If the STOP-Bang score is 5 vs 0-2, the risk of obstructive sleep apnea is 5 fold
Understanding the Results | Sleep Medicine Based on the AHI, the severity of OSA is classified as follows: When a home sleep study is done, the AHI is often expressed as the Respiratory Event Index (REI) The REI is the number of apneas or hypopneas recorded during the study per hour of device recording time
