Summary
This study is aiming at evaluating whether the number and size of exhaled particles changes during the increase and decrease of bronchial constriction in subjects with mild intermittent asthma.
Detailed description
Particle emission demonstrates high reproducibility within subjects while between-subject-variability is large. Methacholine challenge in subjects with mild intermittent asthma will provide data from repetitive measurements in the same subject with variable airflow obstruction.
