- Pre-bronchodilator measurement of Forced Expiratory Volume in one second (FEV1) [ Time Frame: Baseline ]Pre-bronchodilator measurements of FEV1 to determine bronchoconstriction. FEV1 is measured in liters of air. Severity of bronchoconstriction is based on predicted values published by National Health and Nutrition Examination Survey (NHANES III hankinson) for height, weight and age. Predicted values are reported as percent predicted with a result of 80% or greater considered normal
- Pre-bronchodilator measurements of Forced Vital Capacity (FVC) [ Time Frame: Baseline ]Pre-bronchodilator measurements FVC to determine lung volume. FVC is measured in liters of air. Participants predicted vital lung capacity is based on values published by National Health and Nutrition Examination Survey (NHANES III hankinson) for height, weight and age. Predicted values are reported as percent predicted with a result of 80% or greater considered normal
