Abstract

INTRODUCTION

To improve the work efficiency and reduce heat-related illness of emergency rescue personnel, the effects of emergency rescue clothing on physiological and perceptual responses were investigated.

METHODS

Thirteen participants were recruited to perform human trials in a climate chamber wherein the ambient temperature and relative humidity was controlled at 35°C and 75%, and 25°C and 65%, respectively. Moreover, participants wearing emergency rescue clothing (ERC group) and T-shirts and shorts (CON group) walked at 4 and 6 km/h on a treadmill. During the trials, physiological responses and subjective responses were obtained, and then physiological strain index (PSI) and perceptual strain index (PeSI) were calculated.

RESULTS

The results showed significant differences between the ERC and the CON in parameters such as core temperature, mean skin temperature, heart rate, PSI, although some data differences were slightly. There was a positive correlation between PeSI and PSI, as well as between mean skin temperature and thermal sensation vote, with values of 0.93 and 0.94 (ERC), respectively.

DISCUSSION

Correlation analysis shows that PeSI had a potential to predict PSI. This study can replace complex and cumbersome physiological indicators by calculating the perception indicators of emergency response personnel working on site, promoting the development of the safety industry engaged in certain intensity physical labor in humid and hot environments.

摘要

引言

为提高应急救援人员的工作效率并减少与热相关的疾病，研究了应急救援服装对生理和感知反应的影响。

方法

招募了13名参与者在气候室进行人体试验，其中环境温度和相对湿度分别控制在35°C和75%，以及25°C和65%。此外，穿着应急救援服装的参与者（ERC组）和穿着T恤和短裤的参与者（CON组）在跑步机上以4公里/小时和6公里/小时的速度行走。在试验过程中，获取生理反应和主观反应，然后计算生理应变指数（PSI）和感知应变指数（PeSI）。

结果

结果显示，ERC组和CON组在核心温度、平均皮肤温度、心率、PSI等参数上存在显著差异，尽管有些数据差异较小。PeSI与PSI之间以及平均皮肤温度与热感觉投票之间存在正相关，ERC组的相关系数分别为0.93和0.94。

讨论

相关性分析表明，PeSI有预测PSI的潜力。本研究通过计算在现场工作的应急响应人员的感知指标，可替代复杂繁琐的生理指标，推动在湿热环境中从事一定强度体力劳动的安全产业发展。
