Cardiopulmonary Exercise Testing

Also known as: MET test, CPX testing, CPET.

What is cardiopulmonary exercise testing?

Cardiopulmonary exercise testing tests the function of your heart and lungs by means of an exercise test. Breathing and heart rate are monitored as the patient performs the test.

What happens during the procedure?

The patient is equipped with ECG heart monitors and a breathing tube prior to the test. Breathing and heart rate is monitored prior to the test. Then the patient exercises for around 10 minutes, typically on a treadmill or bicycle machine. Additional readings are taken during and after the exercise test.

Is any special preparation needed?

The patient will need to avoid exercise or heavy food consumption for a period of time prior to the test. The patient should also wear comfortable clothing that does not restrict breathing.

What are the risk factors?

The test poses the same risks as moderate exercise, but the test is performed in a safe, controlled environment to address any issues that might come up during the exercise portion of the test.
