Cardiopulmonary Exercise Testing


A cardiopulmonary exercise test is a specialized form of stress testing done to assess the response of your heart and lungs to exercise.  The test is done on a treadmill.  Your heart (EKG), blood pressure, oxygen level and breathing will be monitored while you walk on the treadmill. You will breathe through a mouthpiece during your test.  A pulmonary physician is always present in the office when testing takes place in the unlikely event you should experience any difficulties during your testing. As with any type of exercise, there is a remote possibility of serious medical problems related to changes in blood pressure, irregular heartbeat, fainting, etc.  The length of the test is tailored to each patient. The treadmill starts at a very slow speed.  Depending on your ability, the speed and grade (steepness) of the treadmill will be gradually increased. You will be asked to walk as long as you can, but can stop at any time you experience symptoms that make it impossible for you to continue.  You will be monitored for a few minutes after you stop walking on the treadmill.  Your doctor will review the test results with you at your next visit.
