Central vs Obstructive Sleep Apnea
Obstructive Sleep Apnea
This is the most common form of this sleep disorder. It happens when the tongue and muscles at the back of the throat collapse and block your airway intermittently. One of the most noticeable signs of OSA is snoring. Obstructive sleep apnea may also disturb the sleep of your partner.
Central Sleep Apnea
This happens when your brain does not send proper signals to the muscles that control your breathing. Sleeping at a high altitude and other medical conditions contribute to CSA. Like OSA, snoring can also be present if you have central sleep apnea.
Sleep apnea can lower the level of oxygen in your blood, causing a buildup of carbon dioxide.
