Objective To observe the effects of Ambroxol mucosolvan inhalated by High-pressure jet oxygen atomization to the physical and chemical properties of sputum in patients with chronic obstructive pulmonary disease during acute aggravating period. Method 72 cases of COPD patients with acute aggravating period to give an easy high-pressure jet oxygen atomization inhalation,bathing separately col ected before detect atomization,1 hours after atomization sputum volume,wet/dry weight and viscosity. Results After oxygen atomization,oxygen atomization before amount of sputum,sputum viscosity,sputum dry/wet weight had significant dif erence (p<0.05), and inflammatory biomarkers of neutrophil (PMN) combined with elastic enzyme membrane(HLE) has no obvious change. Conclusion High-pressure jet oxygen atomization inhalation of Ambroxol mucosolvan with dilute sputum and increased sputum volume effect,so as to ease of airway obstruction caused by high mucus secretion,relieve the patient's clinical symptoms,but the inhibition effect of the inflammatory response in the airways of has yet to be further research.%目的：观察高压喷射氧雾化吸入沐舒坦对慢性阻塞性肺疾病（COPD）急性加重期患者痰液理化性质的作用。方法72例COPD急性加重期患者给予沐舒坦高压喷射氧雾化吸入，分别收集检测雾化前、雾化后1h痰液量、干/湿重及黏度。结果氧雾化前与雾化后的痰液量、痰液黏度、痰液干/湿重均有明显差异（P<0.05）。而炎症指标中性粒细胞(PMN)膜结合弹力酶（HLE）无明显改变。结论高压喷射氧雾化吸入沐舒坦有稀释痰液、增加排痰量的作用。从而缓解黏液高分泌所致的气道阻塞、减轻患者的临床症状，但抑制气道炎症反应的作用尚无明确证据。
