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.
