Where this trial is recruiting
Primary endpoints
use exhaled nitric oxide as a surrogate marker of large airway vs small airway/lung inflammation following various doses of inhaled corticosteroids; determine site of airflow limitation, whether predominantly large and /or small airways using expiratory flow volume curves obtained before and after asthmatics breathe a 80% helium-20% oxygen gas mixture; investigate the mechanisms that limit expiratory airflow: intrinsic airway obstruction vs loss of lung elastic recoil; determine the extent of asthma and distribution of emphysema
