CPET
Also written as: CPET — Cardiopulmonary Exercise Testing
Cardiopulmonary Exercise Testing, comprehensive evaluation that simultaneously assesses cardiovascular and respiratory responses to progressive physical exercise.
Full Definition
Cardiopulmonary Exercise Testing (CPET) is a sophisticated diagnostic procedure that evaluates the integrated response of the cardiovascular, respiratory, and metabolic systems during graded physical exercise. The test typically involves cycling or treadmill exercise with continuous monitoring of oxygen consumption (VO2), carbon dioxide production (VCO2), ventilation, heart rate, and blood pressure. CPET provides valuable information for diagnosing exercise intolerance, determining functional capacity, evaluating treatment effectiveness, and assessing surgical risk. The anaerobic threshold, peak oxygen consumption, and ventilatory efficiency are key parameters derived from CPET that help differentiate cardiac from pulmonary causes of exercise limitation.
