What does apnea refer to in medical terms?

Apnea in medical terminology specifically refers to a temporary cessation of breathing. This condition can occur during sleep or while a person is awake. It indicates a momentary stop in the respiratory process, which can lead to decreased oxygen levels in the body. Apnea is often associated with sleep disorders, such as obstructive sleep apnea, where breathing stops repeatedly during sleep due to airway blockage. Understanding apnea is crucial in medical contexts, especially in diagnosing and treating respiratory and sleep-related issues. The other options represent different breathing patterns or issues, but they do not accurately describe the specific definition of apnea.
