  Rationale: Impulse Oscillometry (IOS) is a noninvasive method to measure respiratory impedance. The use of IOS as an indirect measure of airflow obstruction compared to spirometry in the evaluation of Exercise-Induced Bronchoconstriction (EIB) has not been fully explored in children. In this study we aim to describe the IOS values, resistance at 5 Hz (R5rs) in subjects with EIB and without EIB. We also aim to compare whether IOS variables correlate with spirometry variables following exercise challenge test in asthmatic subjects. Methods: We designed a cross sectional study involving subjects between 6-18 years old with a diagnosis of asthma who were referred to the pediatric pulmonary function lab for an exercise challenge test to rule out EIB. Spirometry and IOS were performed at baseline and at 5 minute intervals up to 20 minutes post exerc.. Read More»
