Sleep apnea (or sleep apnoea in British English; /æpˈniːə/) is a type of sleep disorder characterized by pauses in breathing or instances of shallow or infrequent breathing during sleep. Each pause in breathing called an apnea can last from at least ten seconds to several minutes and may occur 5 to 30 times or more an hour. Similarly each abnormally shallow breathing event is called a hypopnea.
