Cardiopulmonary Exercise Testing

A cardiopulmonary exercise test (CPET) is an evaluation of the cardiopulmonary system.
Physical exercise requires the interaction of the physiologic mechanisms that enable the cardiovascular and respiratory systems to support the energy demands of the contracting muscles. Both systems are consequently stressed during exercise. Their ability to respond adequately to this stress is a measure of their physiologic competence.
Studies are performed under the direction of the cardiology and pulmonary divisions
Emphasis of testing may be influenced by the requesting division

• Cardiac patients have more detailed electrocardiogram (ECG)/hemodynamic monitoring during testing
• Pulmonary patient studies may include bronchial provocation with exercise testing

Exercise modalities

• Bicycle ergometer
• Treadmill
• Selection of modality and protocol are dependent upon the requesting physician, level of fitness and health, weight, age, and patient preference
