The test is usually done on a stationary bicycle or treadmill, depending on the child’s age, size, and ability. The child wears a few devices during the test that tell how the exercise is affecting the body.
Small clip that goes on the finger or a pad on the forehead
Tells how much oxygen is in the blood
Small stickers (electrodes) that go on the chest
Watches the heart activity
Blood pressure cuff on the arm or leg
Checks blood pressure
Padded nose clip and mouthpiece or breathing mask
Checks the breathing patterns and how well oxygen goes in and out of the lungs
While exercising, the child is asked to rate the difficulty on a scale of 6-20, with 20 being the hardest. The resistance on the bicycle or treadmill speed and grade gets increasingly harder the longer the child exercises. Your child will exercise as long as possible (parent / guardians can help encourage their child to exercise as long as possible). Once the exercise portion of the test has ended, the child is allowed to rest. Some of the devices stay on the child until the heart rate and blood pressure return to resting values.
