When is PFT Necessary?
We may suggest pulmonary function testing if your child has a chronic pulmonary disease, like cystic fibrosis or bronchopulmonary dysplasia. In most cases, these tests are performed on older children, however, it can be done on infants. When we need to test an infant’s breathing abilities, special equipment is required because they cannot breathe on their own. Please keep in mind that there is more preparation for infant PFTs than for older children.
Children that take medicine to help them breathe may also benefit from pulmonary function testing, as these tests can help us determine whether or not the medicine is working, and how well.
About the Tests
- Spirometry - This is the main test that is conducted. Regardless of the reason your child is being tested, a
spirometry will always be performed. This test does the following:
- Measures how much air can be exhaled from the lungs after the child inhales
- Measures how fast the air is exhaled
