Abstract

We employed a highly sensitive density measuring system to measure the decrease in blood density and plasma density due to the infusion of a saline bolus into the rabbit's circulation. Based on a vasculature model with the Fahraeus effect, we deduced a set of equations to calculate from the density decreases the red-blood-cell volume and plasma volume of the rabbit. A value of 0.82 +/- 0.02 was obtained for Fcell, the ratio of the hematocrit calculated from the two volumes and the arterial hematocrit.

摘要

我们使用了一个高灵敏度的密度测量系统来测量由于向兔子循环系统中注入生理盐水团注而导致的血液密度和血浆密度的降低。基于具有法-林效应的血管模型，我们推导了一组方程，以便根据密度降低值来计算兔子的红细胞体积和血浆体积。由这两个体积计算出的血细胞比容与动脉血细胞比容的比值Fcell为0.82±0.02。
