血红蛋白(Hb)水平是评价儿童的营养状况重要指标,Hb具有携氧的特殊生理功能,其含量受到外界环境氧分压的影响,随着海拔高度的增加环境氧分压逐渐降低,这势必促使人体发生适应性的生理变化,研究表明随着海拔上升,特别是海拔超过10 0 0m以后,Hb含量明显增加。明确两者间的关系,对 Hemoglobin (Hb) level is an important index to evaluate the nutritional status of children. Hb has a special physiological function of oxygen carrying, and its content is affected by the partial pressure of oxygen in the external environment. As the altitude increases, the partial pressure of oxygen in the environment gradually decreases, Human body adaptive physiological changes, studies have shown that as altitude rises, especially at altitudes above 10 0m, Hb content increased significantly. Clear relationship between the two, right
