How is sleep apnea diagnosed?

By John Hawes | Last updated: September 24, 2018

Sleep apnea is a sleep disorder where breathing is interrupted. There are three types of sleep apnea – obstructive sleep apnea, central sleep apnea and complex sleep apnea syndrome. The most common type is obstructive sleep apnea. Obstructive sleep apnea occurs when the muscles in the throat relax, causing the airway to narrow or close off. The brain senses the inability to breathe causing the person to briefly wake up.

Initially a doctor will review a person’s health and sleep history. To diagnose obstructive sleep apnea, a home sleep test may be completed. This is a simple test used at home to measure heart rate, blood oxygen levels and breathing patterns. Based on the results of this test, the person may be referred to a sleep clinic for more extensive overnight testing to monitor brain activity, breathing patterns, movement of extremities, oxygen levels and heart and lung activities.
