Mucus clearance was monitored in nine clinically stable cystic fibrosis (CF) patients. The patients performed: 1) postural drainage with thoracic expansion exercises + forced expiration technique (FET) in the left decubitus position; 2) positive expiratory pressure (PEP)-mask breathing + FET; and 3) physical exercise on a bicycle ergometer + FET. All treatments had the same duration and FET was standardized. Mucus clearance was assessed using a technique based on measurement of the elimination of inhaled radiolabelled particles. Mean clearance of tracer from the right lung by postural drainage, PEP and physical exercise was 18\% (range 10-29\%), 20\% (12-43\%), 16\% (8-25\%), respectively, and from the left lung 20\% (8-42\%), 15\% (5-23\%) and 13\% (5-17\%), respectively. The differences were not statistically significant. Surprisingly, postural drainage (PD) was the most effective technique in the left, dependent lung in 7 of the 9 patients.}, issn = {0903-1936}, URL = {//www.qdcxjkg.com/content/5/6/748}, eprint = {//www.qdcxjkg.com/content/5/6/748.full.pdf}, journal = {European Respiratory Journal} }
