What is a PFT?

A PFT is a painless breathing test that can help the doctor determine if your child's lungs are working properly. A PFT can also help the doctor decide if different kinds of medicines are effective.

Can I be with my child during the test?

In most cases the parents do not stay in the room during testing. It has been found that most children can perform the test better when done one-on-one with the technician.

What should we do before the test?

Read and discuss this information with your child. Tell your child the test does not hurt. Explain how the test is done, especially what your child will see, hear, and feel. Answer as many questions as you can.

If your child is taking a bronchodilator (inhaler or nebulizer) try not to use it within 4 hours before the PFT. This is helpful to the test but not necessary. If your child is wheezing, coughing, or in any respiratory distress, go ahead and give the medicine as prescribed.

How is a PFT done?

The pulmonary function technologist will teach your child a few different ways of breathing. During the test, your child will blow into a tube with force, a lot like blowing out birthday candles.

After these tests, a bronchodilator (a medicine that opens the small airways in the lungs) will be given as a nebulized solution. The breathing test will be repeated to check for any changes.

What are the side effects of the medicine?

Side effects of the bronchodilator are rare and short-lived and may include:

  • trembling
  • fast heartbeat
