The Pulmonary Function Laboratory at Cincinnati Children’s can conduct a number of tests to measure respiratory health. We coordinate with your child’s pediatrician to perform the tests and evaluate the results. Each test involves a different procedure and measures different aspects of your child’s pulmonary function. All testing is overseen by a physician. Your child’s test will be interpreted by a pediatric pulmonary physician and a report will be sent to your doctor.

What are Pulmonary Function Tests (PFTs)

Pulmonary Function Tests measure how well the lungs breathe in air.

PFTs can be used to:

  • Identify if your child or infant has a decrease in lung function
  • Measure the effects of known chronic lung diseases – such as asthma and cystic fibrosis – on your child’s lung function. Asthma tests include Exhaled Nitric Oxide (eNO), Exercise Induced Asthma Test and Methacholine Challenge Test
  • Decide if medication is needed or needs to be adjusted
  • Serve as pre-surgery testing to determine your child’s ability to tolerate medical procedures
  • Determine if intense exercise decreases your child’s lung function
