Acts to hold airways open during expiration, preventing premature airway closure and therefore, reducing gas trapping in lungs iii. Shown to be very effective in enhancing airway secretion clearance, improving lung volumes and expiratory flow in patients with cystic fibrosis, improving oxygenation and exercise tolerance, and can prevent airway collapse.
