基于工效学的高海拔制氧装置制氧效果评价方法研究

目的研究不同制氧装置和供氧方式对装备人员工效的综合影响。方法从不同吸氧方式对高海拔地区装备人员生理、心理、体能和作业效率等方面的改善效果进行研究。结果吸氧后装备人员的血氧饱和度上升到12%左右、心率减缓10%,体力提高5%左右,工作效率提高13%左右。结论高海拔地区吸氧可以提高从总体上提高装备人员的作业能力,长时间持续低浓度吸氧比间隔式高浓度吸氧对人员的生理、体能和工作效率的改善效果更好。

Research on Evaluation Methods for Oxygen Generation Effects by Oxygen Generators in High Altitude Area Based on Ergonomics

Objective To study the combined effects of different oxygen generators and oxygen supply modes on the efficiency of equipment staff. Methods The efficiency improvement effects of different ways of oxygen inhalation on the equipment staff in high altitude area were studied from the aspects of physiological, psychological, physical performance and the working efficiency. Results After oxygen inhalation, the oxygen saturation was improved by about 12%, the heart rate was reduced by 10%, the physical performance was improved by about 5%, and the working efficiency was improved by about 13%. Conclusion Oxygen inhalation in high altitude area could improve the working ability of the equipment staff in general, and long time continuous inhalation of low-concentration oxygen had better improvement effects on the psychological, physical performance and the working efficiency of the staff, when compared to interval inhalation of high-concentration oxygen.
