What does apnea refer to in a physiological context?

Apnea refers specifically to the absence of breathing. In a physiological context, this condition can occur for various reasons, including sleep disorders, respiratory issues, or neurological problems. During an episode of apnea, there is a complete stoppage of airflow into and out of the lungs, which can last for a few seconds to minutes, and it can pose significant health risks due to inadequate oxygenation of the body. Understanding apnea is essential, particularly in nursing, because monitoring a patient's respiratory status is critical for assessing their overall health and for identifying potential emergencies.
