The term that means "difficulty breathing" is dyspnea. It describes a condition where an individual experiences shortness of breath or an uncomfortable awareness of breathing effort. This could manifest as a sensation of not getting enough air or feeling breathless during activities that wouldn’t usually cause such symptoms. It is a common symptom in respiratory and cardiac conditions.

In contrast, bradypnea refers to an abnormally slow respiratory rate, which does not specifically indicate difficulty in breathing. Orthopnea describes difficulty breathing that occurs when lying flat, often relieved by sitting or standing; it is a specific situation rather than a general condition. Apnea indicates a temporary cessation of breathing, which is a different kind of respiratory issue altogether, focusing on the absence of breath rather than the difficulty in the act of breathing. Understanding these distinctions is crucial for identifying and responding to different respiratory issues in clinical settings.
