What term describes a shortness of breath?

The term that describes shortness of breath is "dyspnea." This condition is characterized by the uncomfortable sensation of not being able to get enough air or breathe normally. It can occur in various contexts, including respiratory diseases, heart conditions, or physical exertion. Understanding dyspnea is crucial since it often indicates an underlying health issue that may require evaluation or treatment.

The other options relate to different respiratory or cardiovascular conditions: tachycardia refers to an increased heart rate, bradypnea signifies abnormally slow breathing, and apnea indicates a temporary cessation of breathing. These terms each represent distinct physiological responses, making it important to accurately identify symptoms like dyspnea as a specific type of respiratory distress.
