红细胞增多是对长时间低氧血症的一种生理性反应,最终的血红蛋白浓度通常与血氧胞和度成正比,这种反应使血液提供了较高的携氧能力。某些慢性缺氧的个体,因红细胞压积增高引起的血液粘滞性过高
Erythrocyte is a physiological reaction to prolonged hypoxemia, and the final hemoglobin concentration is usually proportional to the degree of oxygen saturation. This reaction provides the blood with a high oxygen carrying capacity. Some individuals with chronic hypoxia have hyperviscosity due to elevated hematocrit
