Abstract

Lung function measurements with and without a disposable bacterial filter were compared in 60 children. Although statistically significant, the reduction of lung function measurements caused by using bacterial filters was small and clinically irrelevant (2-4% of predicted for forced expiratory volume in one second and vital capacity).
