摘要: This study is a quantitative comparison of the sputum produced by 12 subjects with cystic fibrosis (CF) who received high-frequency chest compression (HFCC) and standard physical therapy (CPT) in randomized order. Six routinely used manual CPT six HFCC. None had acute infections or hospitalization weeks before study.
