Comparison of a positive expiratory pressure (PEP) mask with postural drainage in patients with cystic fibrosis.

The use of a positive expiratory pressure (PEP) mask was compared with postural drainage in the treatment of 10 patients with cystic fibrosis. The patients were allocated randomly in a crossover fashion to the two regimens and evaluated initially by a physiotherapist and over a 4 week treatment period by use of a diary card. There was no significant difference in sputum production or change in lung function between each technique as assessed by the physiotherapist. Diary card evaluation also failed to demonstrate a difference in sputum production, symptom score or peak expiratory flow rate between the 4 week treatment periods. It was concluded that PEP mask therapy is an acceptable and effective alternative to postural drainage in interval therapy of patients with cystic fibrosis, although the patients have tended to revert to postural drainage during acute exacerbations.
