目的分析世居高原、急进高原、高原习服训练、世居平原人群红细胞携放氧的变化。方法应用便携式血氧饱和度检测仪、血氧分析仪、血细胞分析仪,检测世居高原、急进高原、高原习服训练人群血氧饱和度(Sp O2)、氧亲和力(P50)及血红蛋白(Hb)数据并进行比较分析,以观察高原低氧环境对红细胞携放氧的影响。结果急进高原组的氧饱和度显著低于其他3组;氧亲和力数据显示习服组的氧释放能力为4个群组中最高;血红蛋白检测数据显示习服训练组显著高原其他3组,且世居高原人群血红蛋白数据低于其他3组人群。结论世居高原人群对于高原低压低氧环境的适应主要来自于其较高的氧释放能力;世居平原的人群在进入高原初期主要通过血红蛋白值的增加来提高其携氧能力,随着进入高原时间的延长,其释放氧的能力会逐步增加以来适应高原低压低氧的环境。
Objective To analyze the changes of red blood cells carrying oxygen in living plateau, rapid plateau, plateau acclimatization training and resident plain population. Methods The blood oxygen saturation (Sp O2), oxygen affinity (P50) and hemoglobin (Hb) were detected by portable oxygen saturation detector, oximeter and hematology analyzer in the plateau, ) Data and comparative analysis to observe the impact of plateau hypoxic environment on red blood cells carry oxygen. Results The oxygen saturation of the plateau group was significantly lower than that of the other three groups. The oxygen affinity data showed that the oxygen release capacity of the study group was the highest among the four groups. The hemoglobin test data showed that the other three groups were significant in the habit training group Habitat high hemoglobin data was lower than the other three groups of people. CONCLUSION: The adaptation of the plateau population to low-pressure and low-oxygen environment in the plateau mainly comes from its high oxygen release capacity. In the early stage of the plateau population, the population in the native plateau mainly increases its oxygen carrying capacity through the increase of hemoglobin value. The extension of time, its ability to release oxygen will gradually increase to adapt to the low altitude hypoxia environment.
