The pediatric pulmonary function and exercise laboratory at  the Maria Fareri Children’s Hospital at Westchester Medical Center is the only dedicated pediatric laboratory of its kind in the Hudson Valley.  Located at 19 Bradhurst Avenue, Hawthorne, New York, our laboratory is directly across the highway from Westchester Medical Center.


What are Pulmonary Function Tests?
Pulmonary function tests are special breathing tests that permit accurate measurement of lung function in patients of all ages.  These tests are all safe and non-invasive and are essential for both the diagnosis and treatment of any patient with chronic respiratory disease, including Asthma.


Can’t these tests be performed in my doctor’s office?
More and more physicians are now able to make some measurements of lung function right in their office, usually with a test referred to as spirometry.  While spirometry is very helpful, this is by no means the only test of lung function available.  In fact, no one test can completely measure lung function.  Our pediatric pulmonary function laboratory is able to measure lung function in many other ways, including tests that require no effort and therefore are applicable to young children.


What tests are available in the laboratory?
Comprehensive testing including flow measures, lung volumes by body plethysmography and gas dilution, diffusion measures, airway dynamics by plethysmography, airway resistance by IOS, single breath nitrogen washout is offered for all patients 3 years and above. Over 1200 complete PFTs in children are performed each year. Our lab also is equipped with state-of-the-art instrumentation for measurement of pulmonary function in infants and toddlers including measurement of lung volumes, dynamics and flow using both the tidal and raised volume techniques (the “squeeze method). Bronchoprovocation testing by exercise challenge and methacholine challenge is available when needed. All cystic fibrosis patients undergo biannual flow measures in the lab and a complete set of PFTs annually. The laboratory is staffed by two experienced RTs with extensive experience in performing PFTs in young children. The laboratory has been an active part of the fellowship program with all fellows participating in supervision of testing as well as interpretation of all tests through the three years of fellowship. Fellows frequently use the laboratory as part of their research protocols, with several publications over the past few years.
