Exercise Tolerance Testing (Exercise Challenge Test)
If you are suffering from coughing, wheezing, tightness, shortness of breath or poor performance, you might be in need of an exercise tolerance test. With this kind of test, we evaluate the aforementioned symptoms using exercise.
Typically, the patient undergoes a baseline spirometry and pulse oximetry first. Then, exercise is performed either to achieve the symptoms the patient is suffering from, or to hit a specific target heart rate. Spirometry and oximetry are then performed again at five-minute intervals for 30 minutes, while the doctor looks for specific changes in the airflow pattern as well as rate of recovery.
Once the doctor determines a diagnosis of exercise-induced bronchospasm, he or she will design a medication and exercise program to relieve the symptoms.
