Background: Rc-cornet is a hand held PEP device used in facilitating airway clearance. Acapella is also a PEP device already known to be effective in airway clearance. Objective: The objective of the study was to compare Acapella and Rc-cornet device as airway clearance in bronchiectasis subjects and to determine patient preference between the two devices. Method: Forty patients (20 male and 20female) mean age 52.20 __ampersandsignplusmn; 15.66 with history of expectoration of more than 30ml sputum per day were recruited. The sequence of the therapy was allocated by block randomization. Assessment and familiarization session was performed on day 1. Treatment employing the Acapella and Rc-cornet were done on days 2 and 3 . Treatment order and allocation was determined by block randomization. Sputum volume was measured during and 2hours after the treatment and patient treatment preference was recorded. Results: A statistically significant difference was found in the sputum volume expectorated with Rc-cornet (36.58 __ampersandsignplusmn; 7.21) compared with Acapella (34.63__ampersandsignplusmn;9.03). Patients preferred Rccornet in terms of clearing secretions. Conclusion: The present study proved there was increased sputum clearance following the use of Rc-cornet when compared to Acapella. In addition Rc-cornet was preferred by patients who judged that it was more useful in clearing secretions.
