Stages of Sleep Apnea

Table of Contents


Topic Overview

Sleep apnea occurs when you regularly stop breathing for 10 seconds or longer during sleep. It can be mild, moderate, or severe, based on the number of times an hour that you stop breathing (apnea) or that airflow to your lungs is reduced (hypopnea). This is called the apnea-hypopnea index (AHI).

Sleep apnea may be classified differently in children, because they are still developing and they normally breathe at a faster rate than adults do.
