A Cardiopulmonary Stress Test is an exercise test performed on a treadmill intended to measure gas exchange in addition to pulmonary and cardiac activity.  Breathing is done through a special mouthpiece during the test to measure the amount of oxygen going in and the amount of carbon dioxide going out.  This is referred to as “gas exchange.”  This test will determine if the exercise level achieved and maintained is normal for age, sex and gender.

A cardiopulmonary stress test can be done for a variety of reasons. It can help identify an unexplained shortness of breath; detect and evaluate heart failure; evaluate lung function; aid in developing an exercise program; and for surgical evaluation.
