Pulmonary function tests (PFTs) are performed to ensure your child’s lungs are working properly. This type of testing gives us information as to how well your child can breathe and how effective his or her lungs are in bringing oxygen to the rest of the body. When your child comes in to any of our three locations for PFT testing, you can expect a series of tests to be conducted. All of these tests measure the functionality of your child’s lungs, which can help our providers monitor specific conditions and/or symptoms.

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

At Tots N Teens, the length of testing will depend on a host of factors, causing testing to last from 15 minutes to upwards of an hour. Let’s now look at the type of test that we offer:
  • 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
This test can be performed at any of our three Tots N Teens locations in Mesquite, Plano, or Forney. To get the most accurate results possible, it is important that your child does not eat any solid food for at least six hours before the test, and no liquids in the four hours leading up to the test.
