目的 :观测短期进驻高原地区人体脑血流动力学的变化 ;方法 :设立短期进驻高原组与对照组 (平原组 ) ,观察其脑动脉的收缩峰值血流速度 (Vp)及舒张末血流速度 (Vd) ,进行分析对比 ;结果 :短期进驻高原组脑动脉的收缩峰值血流速度 (Vp)及舒张末血流速度 (Vd)均增快。结论 :缺氧可引起脑血流速度加快 ,脑血流量增加
Objective: To observe the changes of cerebral hemodynamics in short-term high altitude area. Methods: To set up short-term altitude plateau group and control group (plain group) to observe the contraction peak cerebral blood flow velocity (Vp) and end diastolic blood flow velocity (Vd). Results: The peak systolic velocity (Vp) and end-diastolic velocity (Vd) of cerebral artery in short-term plateau group increased rapidly. Conclusion: Hypoxia can cause cerebral blood flow speed up, cerebral blood flow increased
