针对三种复苏液治疗失血性休克的血气指标,利用机理分析方法建立了血气指标的微分模型,给出血气指标的指数曲线表达式,并结合试验数据进行了曲线拟合,得到了指数曲线的具体形式,结果与试验数据高度吻合同时分析了用药的效果.利用统计分析方法给出三种复苏液治疗失血性休克的动脉血、静脉血和肠系膜静脉血的血气指标间的回归曲线关系式. According to the blood gas indexes of hemorrhagic shock treated by three resuscitation fluids, the differential model of blood gas index was established by the mechanism analysis method, the exponential curve expression of blood gas index was given, and the curve fitting was made with the experimental data, and the exponential curve The results are in good agreement with the experimental data and the effect of the drug is also analyzed.The regression equation between blood gas indexes of arterial blood, venous blood and mesenteric venous blood of three kinds of resuscitation fluid for hemorrhagic shock is given by statistical analysis method.
