长居海平面试飞人员进入高原工作的机体变化

Change of phsiological function of testpiots working on the highland who have worked for long time in the ynvironment of sealevel

目的 :探讨长居海平面工作和生活试飞人员在高原工作的生理机能变化。方法 :对长居海平面 70名试飞人员 ,在 2 0 0 0m～ 5 0 0 0m处试飞工作中 ,随同问询、诊查机体各系统的生理变化。结果 :低氧分压是高山病各种症状的主要原因 ,加之高原特有的环境因素 ,使人体各系统产生许多异常症状。结论 :生物机体不仅能接受环境因素的变化 ,发生一定的反应 ,而且在某些环境因素下 ,能相应改变自己的生理机能 ,但在适当卫生预防保健措施下 ,绝大多数人可很好地适应 。

OBJECTIVE:To study and discuss the change of physiological function of testpilots working on the highland who live in the environment of sealevel.METHODS:Inquiring and checking the testpilot during their working on highland whose altitued is from 2000M to 5000M.RESULTS:Low partial pressure of oxygen is the primary reason causing symptoms of sickness of mountain and the symptoms will disappear or be conquered after centain period.CONCLUSION:Most testpilot can adapt themselves to the environment of these highland.
