Central Apnea is Characterized By

Question

Central apnea is characterized by:
A)Vigorous chest wall and abdominal muscle activity.
B)Cessation of airflow at the nose.
C)Snoring.
D)Severe hypercarbia.

Accepted Answer

Central apnea is a type of sleep apnea in which there is a cessation of respiratory effort and airflow at the nose and mouth. It is not associated with snoring or vigorous chest wall and abdominal muscle activity. Hypercarbia (elevated levels of carbon dioxide in the blood) may occur as a result of the apnea, but it is not a defining characteristic of central apnea.
