摘要1.1.正常人红细胞的平均比重为1.0971。这一因素在不同的人中是相当稳定的，但在贫血患者中，与正常人群相比，经常会有更大的偏离平均值。2.2.红细胞压积可以根据人体全血和血浆的比重计算出来。此外，仅从全血的比重就可以相当准确地估计红细胞计数、血红蛋白和红细胞压积，因为这些数值彼此之间存在恒定的关系。3.3.全血比重、血红蛋白浓度、红细胞压积和红细胞计数作为血液浓缩和相对血容量变化的指标是一致有效的。4.4.在休克过程中，蛋白质浓度或血浆比重不是一个令人满意的血液浓缩指标，因为蛋白质从循环血液中丢失。
Abstract 1.1. The average specific gravity of normal human erythrocytes is 1.0971. This factor is fairly constant in different persons, but in anemia there frequently is a greater departure from the average than in normals. 2.2. The hematocrit may be calculated from the specific gravity of whole blood and of plasma in human beings. Also a fairly accurate estimate of red blood cell count, hemoglobin, and hematocrit may be made from the specific gravity of whole blood alone, since these values bear a constant relationship to one another. 3.3. Specific gravity of whole blood, hemoglobin concentration, hematocrit, and red blood cell count are uniformly efficacious as indicators of hemoconcentration and relative blood volume change. 4.4. Protein concentration or specific gravity of plasma is not a satisfactory indicator of hemoconcentration during the course of shock, since protein is lost from the circulating blood.
