摘要支气管扩张症是一种慢性结构性肺部疾病，其特征是慢性咳嗽、咳痰、运动能力下降，这些症状在急性加重期间恶化，严重影响生活质量。气道黏液管理、肺康复治疗在支气管扩张症患者的管理中占据重要地位，尽管证据基础相对薄弱。现主要就气道廓清技术的生理学原理、支持证据和肺康复治疗在支气管扩张症中的应用及进展作一综述。

abstractsBronchiectasis is a chronic, structural lung disease characterized by chronic cough, sputum production, and decreased exercise capacity. These symptoms worsen during exacerbations and impact negatively on health-related quality of life. Airway mucus clearance and pulmonary rehabilitation play an important role in the management of bronchiectasis, despite a relatively weak evidence base. Thus, the paper reviews the physiological rationale and clinical evidence of airway clearance techniques (ACTs), application and research progress of pulmonary rehabilitation in the management of bronchiectasis.
