The objectives of this prospective, non-pharmacologic interventional cohort study are to determine the effect of four consecutive weeks of twice-daily or greater OPEP usage among patients with COPD with a chronic bronchitis (sputum-producing) phenotype on disease impact and on respiratory system dynamics. A 'dose-response' effect of OPEP use will also be investigated. We hypothesize that a 4-week period of OPEP therapy among eligible patients with COPD with a chronic bronchitis (sputum-producing) phenotype will be associated with improved disease impact scores and airway mechanics.
