Watch a video about the exercise induced asthma test.
In this test, your child will first breathe into a spirometer to measure airflow rate. Your child will exercise on a treadmill to reach a target heart rate. The therapist will measure heart rate, and blood oxygen levels during the exercise, and will ask your child to rate their level of exertion. After the run, your child will complete spirometry tests every five minutes for 30 minutes, to measure lung function after exercise. Your child should not eat three hours before the test, and your child’s physician may have your child stop taking certain medications prior to the test. This test lasts about 90 minutes to two hours.
