What term describes a total absence of breathing?

The term that describes a total absence of breathing is apnea. This condition is characterized by the temporary cessation of respiration, leading to a stop in airflow to and from the lungs. Apnea can occur for various reasons, such as during sleep (as seen in sleep apnea) or due to medical conditions affecting the respiratory system. It is important to identify and address apnea promptly, as it can result in decreased oxygen levels in the blood and can potentially be life-threatening if not treated.

Bradycardia refers to a slower than normal heart rate, while hypoxia describes a deficiency of oxygen in the tissues. Hyperventilation is characterized by rapid or deep breathing, often leading to decreased carbon dioxide levels in the blood, which is opposite to the state of apnea. Understanding these terms and their implications is critical in nursing and medical practice to provide appropriate care.
