摘　　要：目的:探讨肺泡-动脉氧分压差(A-a DO2)和氧合指数(OI)动态监测在重症肺炎并发ARDS机械通气中的应用。方法:收集98例重症肺炎并发ARDS患者随机均分为研究组与对照组,比较两组患者的疗效差异。结果:研究组患者的治疗总有效率高于对照组(P<0.05),机械通气时间、治疗总时间、肺功能恢复时间低于对照组(P<0.05);治疗后,两组患者的呼吸功能和血流动力学参数均有改善(P<0.05),且研究组改善更明显。结论:动态监测重症肺炎并发ARDS患者的A-a DO2和OI并根据变化随时调整治疗,能够明显改善患者的呼吸功能,提高治疗效果,具有良好的临床价值。Objective:To explore the application value of A-a DO2 difference and OI dynamic monitoring in severe pneumonia complicated with ARDS mechanical ventilation.Methods:Ninety-eight patients with severe pneumonia complicated by ARDS were collected and randomly divided into the study group and the control group to compare the efficacy difference.Results:The total effective rate of treatment of the patients in the study group was higher(P<0.05),and the time of mechanical ventilation,total time of treatment,and the time of recovery of lung function were lower(P<0.05);the respiratory function and haemodynamic parameters of the patients in the two groups improved after treatment(P<0.05),and the improvement in the study group was more obvious.Conclusion:Dynamic monitoring of A-a DO2 and OI in patients with severe pneumonia complicated by ARDS and adjusting the treatment at any time according to the changes can significantly improve the respiratory function of the patients and enhance the therapeutic effect,which has good clinical value.
