【摘要】：目的研究实验用密闭服在不通风条件下对人体生理机能的影响及其防窒息的作用。方法 5名年龄为 1 8～ 2 1岁的健康男性分别在密闭服调节阀开关被置于A和B两种不同位置的密闭服中进行测试。结果 (1 )在清醒静卧 ,外界大气压为 1atm的条件下 ,被试者在面窗关闭且调节阀与外界相通的密闭服中 ,耐受时间至少可达 1 5min ;(2 )被试者口前区O2 和CO2 分压在头盔面窗关闭 5～ 7min后都可出现一个平衡状态 ,并持续到实验结束 ;(3 )在 8～ 1 0min的平衡时间内 ,口前区O2 分压在 1 5.0～1 6 .4kPa范围内 ,处于轻度缺氧状态 ;CO2 分压在 5.2 1～
[Abstract]:Objective to study the effect of airtight clothing on physiological function of human body and its anti-asphyxia effect. Methods five healthy men, aged 18 ~ 21, were tested in a closed close-suit with the control valve switch placed in two different positions (A and B). Results 1) under the condition of awake lying still and external atmospheric pressure of 1atm, the subjects were in the closed suit with the face window closed and the regulating valve communicating with the outside. The tolerance time was at least 1 5min / 2) the partial pressure of O _ 2 and CO2 in the preoral area of the subjects appeared a balanced state after the helmet window was closed for 5 ~ 7min, and lasted until the end of the experiment, and lasted within the equilibrium time of 8 ~ 1 0min. The partial pressure of O _ 2 in the preoral area is in the range of 15.0 ~ 16.4kPa, and the partial pressure of CO _ 2 is 5.21 ~ (-1) in the mild anoxic state.
