Testing and treatment. Sleep apnea is diagnosed using an overnight polysomnogram (PSG), or sleep study. (1,2,3) A PSG is conducted overnight at a sleep laboratory. Several monitoring devices continuously measure breathing, blood oxygen levels, heart rate, limb movements and more.
Stages of Sleep Apnea. 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).
