摘要: 为预防高CO2体积分数(即浓度)损伤人员机体,保障地下人员安全,基于人体隔绝试验,分析地下人员对CO2体积分数的生理响应特征。在苏州某地下人防工程中,对170名受试者进行12 h密闭隔绝现场试验,监测不同CO2体积分数下(0.1%~1%),人员心率、血压、血氧饱和浓度、心电(ECG)、皮肤电和静态脑电变化特性,分析心率变异性(HRV)及皮电反应。研究结果表明:短期暴露在CO2体积分数不高于0.7%的环境中不会引起人体显著的生理响应;CO2体积分数上升至0.85%时,受试者心率和HRV显著降低,HRV低频功率(LF)及高频功率(HF)、HRV中快速变化成分和舒张压显著升高;CO2体积分数达到1%时,受试者皮肤电导及皮电水平显著降低;此外,CO2体积分数升高,受试者α波节律被抑制,β波及KC复杂度增加。

Abstract: In order to prevent physiological damage caused by high CO2 level and ensure security of occupants in underground space, their physiological responses to CO2 level were analyzed based on human isolation experiment. A natural isolation experiment was performed with 170 subjects for 12 h in an underground civil air defense project in Suzhou. Changes of their heart rate, blood pressure, blood oxygen saturation, electroencephalogram, electrodermal activity, and electroencephalography were measured at different CO2 levels (0.1%-1%), and HRV and electrodermal response were analyzed. The results show that there are no significant physiological responses when CO2 concentration is no higher than 0.7%. When it rises to 0.85%, subjects' heart rate and HRV decrease obviously while low frequency (LF), high frequency (HF) and rapidly changing components of HRV and diastolic blood pressure all increase significantly. And as it grows to 1%, remarkable skin conductance and skin conductance level are recorded. Furthermore, suppressed alpha wave, increased beta wave andKC(Kolmgorov Complexity)complexity are also observed along with increase of CO2level.

Key words: underground engineering, CO2 level, physiological response, isolation experiment, heart rate variability(HRV)
