What is the difference between central sleep apnea and regular apnea?

What is the difference between central sleep apnea and regular apnea?

Obstruction vs CO2: Central apnea is caused by the brain's inability to respond to elevated co2 (carbon dioxide) levels in the blood. Obstructive sleep apnea is caused by the collapse of the airway when the muscles of the throat, tongue, and possibly the palate when they are flaccid/paralyzed during the deeper stages of sleep. Osa responds well to CPAP and dental devices. Central may not. ...Read more

Apnea (Definition)

This is the cessation of breathing for 10 seconds or more. Most apnea is obstructive being caused by collapse or obstruction of the airway leading to lack of air flow.
