数据说明

Conditions: Cystic Fibrosis (CF). Cystic fibrosis (CF) is a life-limiting autosomal recessive genetic disorder caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Dysfunction of the CFTR protein leads to impaired chloride and water transport across epithelial surfaces, resulting in the production of thick, dehydrated secretions in multiple organ systems, particularly the respiratory tract. The accumulation of viscous mucus within the airways contributes to chronic airway obstruction, recurrent pulmonary infections, persistent inflammation, progressive lung damage, and declining respiratory function. Despite advances in pharmacological treatment and supportive care, pulmonary complications remain the leading cause of morbidity and mortality in individuals with cystic fibrosis. Airway clearance therapy is a fundamental component of respiratory management in patients with CF. The primary objective of airway clearance techniques (ACTs) is to mobilize and remove retained airway secretions, thereby improving ventilation, reducing airway obstruction, minimizing infection risk, preserving lung function, and enhancing quality of life. Various ACTs are available and are routinely incorporated into multidisciplinary CF care programs. However, determining the most effective airway clearance strategy remains challenging because patient responses vary and comparative evidence among techniques is often limited. Autogenic drainage (AD) is an airway clearance technique based on controlled breathing at different lung volumes. The technique consists of three phases: unsticking, collecting, and evacuating secretions. Through carefully regulated inspiratory and expiratory airflow, AD promotes mucus mobilization from peripheral airways toward central airways where it can be effectively expectorated. Because the technique relies on self-regulated breathing rather than external mechanical forces, it may improve patient comfort, encourage independence, and facilitate long-term adheren
