Learning Objective 1: The learner will be able to know the effect of high frequency chest wall oscillation(HFCWO) for airway clearance in people with cystic fibrosis.
Learning Objective 2: The learner will be able to know which one is better comparing HFCWO and conventional chest physiotherapy in people with cystic fibrosis.
First, we used "cystic fibrosis" AND "high frequency chest wall oscillation" as key words to search all related studies in empirical databases. Then, using an appraisal tool to appraised the selected four articles. Finally, using Review Manager 5 to do meta-analysis. Outcome indicators were the amount of dry sputum weight and wet sputum weight in one week and two week. All of results were shown no significant difference between the two groups. We did not find any evidence that HFCWO was better than conventional chest physiotherapy in the included trials. More adequately-powered long-term randomised controlled trials are necessary. Thererfore, health providetrs should consider the needs of their patients and recommend the most suitable method of airway clearance for the individual.
