Participation in airway clearance techniques (ACT) is important to minimise development of irreversible airway obstruction in patients with cystic fibrosis (CF). Positive expiratory pressure (PEP) and expiratory resistance devices (ERD) are often used as they can improve collateral ventilation and aid in the shearing of mucus from airways. This project looked to identify whether utilising an ERD during a forced expiration technique (FET) improves ease of expectoration, sputum amount and coughing frequency in patients with CF.

利用呼气阻力对成人囊性纤维化患者进行改良用力呼气技术

参与气道清除技术（ACT）对于最大程度地减少囊性纤维化（CF）患者不可逆气道阻塞的发生非常重要。经常使用呼气正压 (PEP) 和呼气阻力装置 (ERD)，因为它们可以改善侧支通气并帮助剪切气道中的粘液。该项目旨在确定在强制呼气技术 (FET) 期间使用 ERD 是否可以改善 CF 患者的排痰难度、痰量和咳嗽频率。
