摘要
模拟高海拔高温高湿隧道作业环境,研究环境温度和大气压力及其交互作用对人体生理指标的影响,分析了人体生理指标受环境参数影响的规律和显著性。实验结果表明,人体口腔温度、平均皮肤温度、心率、舒张压、血氧饱和度和失水率受环境温度的影响显著(p<0.05);人体平均皮肤温度、心率、收缩压、舒张压、血氧饱和度和失水率受大气压力的影响显著(p<0.05);人体平均皮肤温度、心率、血氧饱和度受环境温度和大气压力交互作用的影响显著(p<0.05)。该研究可为高温高湿低压低氧环境下作业人员的生理状态监测提供指导。
This paper simulates the high altitude,high temperature and high humidity tunnel operating environment,studies the effects of ambient temperature and atmospheric pressure and their interactions on human physiological indicators,and analyzes the laws and significance of human physiological indicators influenced by environmental parameters.The experimental results showed significant differences(p<0.05)in the effects of ambient temperature on human oral temperature,mean skin temperature,heart rate,diastolic blood pressure,oxygen saturation,and water loss rate.There were significant differences(p<0.05)in the effects of atmospheric pressure on human mean skin temperature,heart rate,systolic blood pressure,diastolic blood pressure,oxygen saturation,and water loss rate.The interaction of ambient temperature and atmospheric pressure significantly affected human mean skin temperature,heart rate,and oxygen saturation(p<0.05).This study can guide monitoring the physiological status of operators in high temperature,high humidity,low pressure,and low oxygen environments.
