慢性阻塞性肺疾病急性加重期(AECOPD),是慢性阻塞性肺疾病(COPD)死亡的主要原因,COPD的特点是气流气道受限制,肺功能减退,严重影响患者的生活质量。由于支气管-肺部感染诱发AECOPD,造成肺功能急剧恶化,死亡率较高。由于COPD的患者气道内黏液高分泌,加重了气道的阻塞,因此要清除气道多余的分泌物,保证气道通畅,才能更有效地机械通气~[1]。支气管灌洗联合无创通气是临床上治疗AECOPD较为理想的
The acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is the leading cause of death in patients with chronic obstructive pulmonary disease (COPD). COPD is characterized by airflow limitation and impaired lung function, which seriously affects the quality of life of patients. As AECOPD is induced by bronchus-lung infection, lung function deteriorates dramatically and mortality is high. Because COPD patients with mucus hypersecretion in the airway, increased airway obstruction, so to remove excess airway secretions to ensure airway patency in order to more effective mechanical ventilation [1]. Bronchial lavage combined with non-invasive ventilation is more ideal for the treatment of AECOPD clinically
