Pulmonary Clinic

Providing Treatment for Lung Disease

The Pulmonary Clinic at Arkansas Children’s provides infants and children with complete diagnosis and treatment of acute and chronic lung disease. It is the only Cystic Fibrosis Center in the state reviewed and approved by the national Cystic Fibrosis Foundation. 

Conditions We Treat

Specialists at the Pulmonary Clinic treat both common and complex conditions including:

  • Asthma
  • Bronchopulmonary dysplasia
  • Chronic bronchitis
  • Cystic fibrosis
  • Interstitial lung disease
  • Lung problems caused by neuromuscular disease
  • Noisy breathing
  • Obstructive sleep apnea
  • Primary ciliary dyskinesia
  • Recurrent pneumonia
  • Technology-dependent children
  • Wheezing

State-of-the-Art Lung Function Tests

Pulmonary function tests, called PFTs, are tests that see how well your lungs work. They are the most often ordered pulmonary lab tests. Our Pulmonary Clinic is staffed by Licensed Respiratory Care Practitioners and performs many tests to help physicians check a patient’s lung health. To accurately diagnose and treat lung conditions in children, we offer pulmonary function tests such as:

  • Spirometry: A common office test, this is used to see how well your child’s lungs work. It measures how much air is inhaled, and how much and how quickly it is exhaled.
  • Pre-Post Bronchodilator Study: This test uses spirometry to see if the narrowed airways caused by asthma and other respiratory diseases can be reversed.
  • Lung Volumes: A test that measures the total size of your lungs (how big they are) and how the air is distributed through the lungs.
  • Diffusion Capacity: This test measures the transfer of gas from air in the lungs to the red blood cells in lung blood vessels.
  • Cough Peak Flow:  This test monitors expiratory muscle weakness and bulbar involvement. The CPF is the speed of air coming out of the lungs after a cough, usually after taking in a very deep breath.
  • Maximum Inspiratory Pressure: This test measures maximal inspiratory pressure.
  • Maximum Expiratory Pressure: This test measures maximal expiratory pressure.
  • Exercise-Induced Bronchoconstriction Study: A test to measure exercise-induced bronchoconstriction (EIB) or acute airway narrowing that occurs as a result of exercise.
Different types of PFTs can be done depending on the age of the child. Each test requires a certain level of cooperation for the test to be successful and accurate. Because our team works only with children, we know how to help children feel comfortable with tests for better outcomes. We also provide infant lung function testing in the main pulmonary lab.

Pulmonary Laboratory Evaluates Lung Capacity

The Pulmonary Laboratory performs several other tests to check lung capacity in children, including:

  • Bronchoscopy: This test lets the doctor look at your child’s airways using a flexible optic material with a light source and a camera on the end.
  • Cold-Air Challenge: To measure specific airway resistance after the introduction of cold air in the lungs.
  • Helium Dilution: This test measures the functional residual capacity of the lungs or the volume left in the lungs after breathing out normally.
  • Lung Volumes: This test measures the size of the lungs and how the air is distributed through the lungs.
  • Six Minute Walk Tests: This is a submaximal exercise test that measures the distance walked over a span of 6 minutes.
  • Spirometry (lung function test) and Bronchodilator Response: This test is often called a reversibility test. It uses spirometry to check possible reversibility of bronchoconstriction in diseases such as asthma.
  • Sweat Testing: This test measures the concentration of chloride that comes out in sweat. It is used to screen for cystic fibrosis (CF).
