人类活动向地理学领域的扩展使我们格信．将会有一种客观的方法来评价高原应激程度。我们用传感脉冲血氧计测定了健康高山徒步者在静息和运动后即刻的动脉氧饱和值。在远留高原100天期间内（400Om高低）．静息状态时的动脉血红蛋白氧饱和值是相对稳定的。但是当到达高原，甚或
The extension of human activities to the field of geography has convinced us. There will be an objective way to assess the degree of stress in the plateau. We measured the arterial oxygen saturation values at rest and after exercise by using a sensing pulse oximeter. Stay in the plateau within 100 days (400Om high and low). Arterial hemoglobin oxygen saturation at rest is relatively stable. But when it reaches the plateau, or even
