Mayo Clinic – Central sleep apnea: Definition, Symptoms, Causes, Risk Factors, Complications

Central sleep apnea is a disorder in which your breathing repeatedly stops and starts during sleep.

Central sleep apnea occurs because your brain doesn’t send proper signals to the muscles that control your breathing. This condition is different from obstructive sleep apnea, in which you can’t breathe normally because of upper airway obstruction.

Central sleep apnea is less common than obstructive sleep apnea.

Central sleep apnea may occur as a result of other conditions, such as heart failure and stroke. Sleeping at a high altitude also may cause central sleep apnea.

Treatments for central sleep apnea may involve treating existing conditions, using a device to assist breathing or using supplemental oxygen.
