Cardiopulmonary Stress Test (CPET)

A CPET is a stress test that includes the addition of pulmonary measurements. This is achieved by wearing a mouthpiece that collects breath-by-breath measurements of inhaled oxygen and exhaled carbon dioxide. A baseline pulmonary capacity test is performed on every athlete prior to starting exercise. Analyzing both cardiac and pulmonary function allows us to determine the source of any problems. We can also use this test to determine anaerobic threshold and maximal oxygen consumption for athletes looking to enhance performance.

CPET testing is most commonly ordered for patients with new or worsening unexplained shortness of breath, but can also be used as a prognostic measure for patients with congestive heart failure. The test typically takes about 60 minutes and can be done on a treadmill or bike. Please follow the same instructions as the exercise tolerance test.
