Short-Term Effects of Chest Physiotherapy on Pulmonary Function in Children with Cystic Fibrosis

Abstract
In a short-term controlled study of 20 patients with cystic fibrosis [chest disease] and chronic sputum production, chest physiotherapy resulted in a significantly improved peak flow over a whole day, with no significant difference in other forced expiratory flows, when compared to a control day. Physiotherapy may be effective in enhancing clearance of sputum from central large airways, but it has little obvious effect on more peripheral airways. A bronchodilator given before physiotherapy had no added effects.
