[Expert consensus on clinical application of mechanical airway clearance techniques].

Mechanical airway clearance techniques refer to the therapeutic method of using mechanical means to clear airway secretions and maintain airway patency. Currently, mechanical airway clearance techniques are widely used in clinical practice and have significant effects in clearing respiratory secretions, improving symptoms of respiratory distress, and preventing and reducing respiratory tract infections. However, up to now, there is no consensus, guidance, or standardized procedures for the clinical application of mechanical airway clearance techniques. Therefore, the Respiratory Care Group of Chinese Thoracic Society organized relevant experts to write the consensus on the clinical application of mechanical airway clearance techniques, and systematically describe the definition, historical development, working principles and mechanisms, and clinical applications of mechanical airway clearance techniques. The aim is to increase awareness of mechanical airway clearance techniques, to provide clinical practitioners with standardized procedures for the application of mechanical airway clearance techniques, and to guide the standardized clinical practice.机械气道廓清技术是指通过机械方法清除气道淤积分泌物、维持气道通畅的治疗手段。目前机械气道廓清技术在临床中应用广泛，在清除呼吸道分泌物、改善呼吸困难症状、预防和减少呼吸道感染等方面有显著作用，但有关机械气道廓清技术临床应用的专业指导和规范流程尚未达成共识，因此，中华医学会呼吸病学分会呼吸治疗学组组织相关专家撰写了机械气道廓清技术临床应用专家共识。共识对机械气道廓清技术的定义、发展历史、工作原理和作用机制及临床应用等方面进行了系统性阐述，旨在增强对机械气道廓清技术的认知，为临床工作者提供规范的机械气道廓清技术应用流程，指导临床规范应用。.
