摘要
本文阐述了在不同高度上人体急性缺氧实验的主要结果。1、用视觉诱发电位检测暗适应,较生理心理学方法灵敏、客观。2.综合功效与脑电是评价脑活动水平与效率的有效的客观手段。意识障碍时,高幅δ波节律丧失,波幅锐减。3.呼吸与循环功能通过3种类型的协同效应实现其代偿活动。4.周期性呼吸与循环代偿障碍是代偿不全的体现。5.轻度体力负荷可改善缺氧不良反应。6.按5种生理界限值制定了高空急性缺氧反应区域。本文资料有理论与实用价值。
This paperdescribes the main results of the experiment or human acute
hypoxia at different altitudes.In determination of dark adaptation the
method of Visual evoked potential was more sensitive and objective
than that of physiological psychology.Complex performance and EEG
were the effective and objective means in evaluating activity level and
efficiency of brain.The respiratory and circulatory functions showed
their compensation activities through three types of aynergetic effects.
Per(?)odic breathing and circulatory disfunction were the expressions of
compensation deficiency.Light exe cise improved the unfavorable rea-
ction of to hypoxia.Acute hypoxia reaction zones at altitude were
formed according to five physiological limit values.
