Abstract: Objective To study the elimination rate of bloodalcohol and estimation of blood alcohol concentration in human.Method Blood alcohol concentration curves were plotted for 95human subjects after they drank various doses of alcoholicbeverage. Result The elimination of blood alcohol conformedwith the mode of linear elimination, with correlated coefficient(r) of -0.989±0.011. The elimination rate of blood alcohol was-0.140 mg·ml-1·h-1±0.028. Conclusion The blood alcoholconcentration can be estimated according to the elimination rateof blood alcohol [-0.10 mg·ml-1·h-1].[

摘要： 目的 研究人血中酒精消除速度与血中酒精浓度的推算关系。方法 用呼气式酒精测定仪测定95位自愿受试者饮酒后一定时间内的血中酒精浓度,对时一浓曲线进行分析。结果 血中酒精的消除符合线性消除规律,消除线性相关系数为-0.989±0.011,最小值为-0.098,最大值-1.000;血中酒精消除速度为-0.140 mg·ml-1·h-1±0.028,最小值为-0.098 mg·ml-1·h-1,最大值-0.230 mg·ml-1·h-1。结论 血中酒精浓度可依据酒精消除速度[-0.10mg·ml-1·h-1]进行回推算。
