Types of Sleep Apnea

A diagram comparing obstructive sleep apnea (OSA) and central sleep apnea (CSA)

Obstructive Sleep Apnea

The most common type of Sleep Apnea is Obstructive Sleep Apnea (OSA). OSA occurs when the upper airway is blocked, usually when the soft tissue in the rear of the throat collapses and closes during sleep.

Central Sleep Apnea

In Central Sleep Apnea (CSA) the airway is not blocked, but the brain fails to send the proper signals to the muscles that control breathing.

Mixed Sleep Apnea

Mixed Sleep Apnea, or Complex Sleep Apnea, is caused by a combination of etiologies.
