dyspnea
Pronunciation: DISP-nee-ah
Difficulty breathing or shortness of breath, often experienced during exertion in cardiac patients.
Full Definition
Dyspnea is the medical term for difficulty breathing or the subjective sensation of shortness of breath. In cardiac rehabilitation contexts, dyspnea is a critical symptom that may indicate cardiac decompensation, exercise intolerance, or underlying pulmonary complications. It can occur at rest or be precipitated by physical exertion, and its severity is often assessed using standardized scales such as the Borg dyspnea scale. Dyspnea may result from various causes including heart failure, ischemia, arrhythmias, or pulmonary edema. Exercise professionals must be trained to recognize and respond appropriately to dyspnea during exercise sessions, as it may require immediate activity cessation and medical evaluation.
Usage
Usage note: Often misspelled as 'dyspnoea' (British spelling); use American spelling in US clinical documentation.
