American Thoracic Society publishes new statement on pulmonary function testing in childrenJune 25, 2007
"Preschoolers present a number of special challenges," said Stephanie Davis, M.D., co-chair of the 33-member ATS/ERS working group that produced the guidelines. "The children are generally too old to sedate, as is done with infants, and less cooperative than an older child. However, investigators have demonstrated that preschool lung function testing is now feasible."
The working group hopes its recommendations-which focus on spirometry, tidal breathing measurements, the interrupter technique, forced oscillation, gas washout techniques and bronchial responsiveness tests-will serve as a resource for healthcare professionals and facilitate good laboratory practices by providing guidelines on how to perform the various techniques and how to interpret the measurements.
"Evaluating lung function in this age group is important, not only for clinical reasons, but also due to the considerable growth and development of the respiratory system that occurs with associated changes in lung mechanics," said Dr. Davis. "The working group envisions that these guidelines will help facilitate multi-center collaboration using these pulmonary function testing techniques," said Dr. Davis.
