Medical Definition of Apnea, central sleep
There are two types of sleep apnea: central and obstructive.
- Central sleep apnea occurs when the brain fails to send the appropriate signals to the breathing muscles to initiate respirations.
- Obstructive sleep apnea occurs when air cannot flow into or out of the person's nose or mouth although efforts to breathe continue.
Central sleep apnea is less common than obstructive sleep apnea.
