世居平原的人进驻高原后,由于大气缺氧的影响,会使人体发生一系列的高原缺氧反应,劳动能力受到明显影响。特别是在高原低氧环境下,人体动脉血氧分压下降,心、肺功能的储备能力下降,组织细胞缺氧,从而导致机体活动能力下降。高海拔低氧环境下人体在体力活动时,心血管系统动力学的活动在输送氧到活动的肌肉方面有着决定性的作用,血流动力学的时效应和力效应发生改变以适应体力活动,最重要的现象就是心率增快,心输出量增加。红景天独特的适应原样作用和双向调控作用能提高机体对不同刺激的稳定性,使不同刺激引起的异常反应向常态回归转移。本文旨在探讨高原缺氧环境下人 Living in the plains of the people stationed in the plateau, due to the impact of atmospheric hypoxia, the human body will occur a series of plateau hypoxia, labor ability was significantly affected. Especially in the plateau hypoxia environment, the human arterial partial pressure of oxygen decreased, heart, lung function reserve capacity decreased, hypoxia tissue, resulting in decreased activity of the body. In high altitude hypoxia environment, the human body during physical activity, cardiovascular system dynamics in the transport of oxygen to the active muscle has a decisive role, hemodynamic changes in the time and force effects to adapt to physical activity, the most An important phenomenon is the heart rate increased cardiac output increased. Rhodiola unique to adapt to the original role and two-way regulation can improve the body’s stability to different stimuli, so that different stimuli caused by abnormal reactions to the normal regression. This article aims to explore the human plateaus hypoxia environment
