Detection of Unsuspected Small Airways Obstruction in Cystic Fibrosis
The Measurement and Analysis of Maximal Expiratory Flow Volume Loops at Low Lung Volumes in Children With Cystic Fibrosis and Normal Routine Lung Function.
About This Trial
Goal is to physiologically detect unsuspected small airways obstruction in children and adults with treated heterozygous and homozygous cystic fibrosis. Unsuspected refers to normal routine pre bronchodilator spirometry including normal FEV1(L), FVC (L). and FEV1/FVC%. This is a retrospective study.
