Pulmonary Function and Infant PFT Laboratories

The Division oversees two fully equipped, modern pediatric pulmonary function laboratories staffed by specially trained technicians and respiratory therapists at LeBonheur Children’s Medical Center and St. Jude Children’s Research Hospital. These laboratories provide state-of-the art testing for children from the Mid-South on both an inpatient and outpatient basis. Tests provided include spirometry (approximately 250 studies per month ), specialized bronchoprovocation testing, measurement of lung volumes by plethysmography, and measurement of carbon monoxide diffusing capacity. In addition, indirect calorimetry can be performed on selected children using our metabolic cart equipment. Our infant pulmonary function laboratory, one of only 39 such laboratories in the United States and the only one in the state of Tennessee, provides spirometry and plethysmographic lung volume measurements in infants with lung disorders. All pulmonary function tests are interpreted by pediatric pulmonology division faculty.
