Which term describes difficult or labored breathing?

The term that describes difficult or labored breathing is dyspnea. Dyspnea can manifest as shortness of breath, a feeling of not being able to get enough air, or an increased effort to breathe. It can be caused by various factors, including respiratory conditions, heart issues, or anxiety. Understanding this term is crucial in the medical field, as it is an important symptom that indicates the presence of an underlying health issue.

In contrast, apnea refers to a temporary cessation of breathing, while hypoxemia indicates low levels of oxygen in the blood. Hyperventilation is characterized by rapid or deep breathing, often resulting in decreased carbon dioxide levels in the blood. By recognizing dyspnea, healthcare providers can assess and address the underlying causes of a patient's respiratory distress effectively.
