    Through the Cystic Fibrosis Center and the Division of Pediatric Pulmonology, Stony Brook Children’s provides specialized infant pulmonary function testing (iPFT), using new equipment capable of measuring the lung function of tiny premature babies, infants, and toddlers. In addition, we also offer pediatric pulmonary function testing capabilities, which includes full pulmonary function testing, exercise testing, cold air challenge, and the six minute walk test.

    Very few cystic fibrosis centers in the country have infant pulmonary testing equipment, and Stony Brook Children’s is the only one on Long Island and the greater New York City area with this capability. The technology is particularly valuable in diagnosing breathing problems in premature infants and children less than two years of age.

    The iPFT machine also helps safely assess the smallest premature and most vulnerable patients with bronchopulmonary dysplasia, congenital abnormalities like diaphragmatic hernia, and bronchiolitis. Lung function in older children is checked through a test called spirometry, which measures airflow as a child blows out into a tube. When children are too young, or when they are unable to follow instructions, lung function is measured with infant pulmonary function testing (iPFT) which requires special equipment to measure lung function while the child is asleep.
