Apnea:
Definition: Apnea is a medical term that refers to the temporary cessation of breathing, often characterized by the absence of airflow through the nose and mouth.
Types of Apnea:
a. Obstructive Sleep Apnea (OSA): This is the most common type and occurs when the throat muscles relax excessively during sleep, leading to a temporary blockage of the upper airway.
b. Central Sleep Apnea (CSA): CSA is less common and is caused by a failure of the brain to transmit proper signals to the muscles that control breathing.
c. Mixed Sleep Apnea: This type involves a combination of both obstructive and central components.
