大量医护人员响应了2013年西非埃博拉病毒病（EVD）爆发的救援和遏制援助。医护人员必须穿着个人防护服（PPC）以阻止病毒的传播;然而，不透水的设计和湿热的环境会导致热应激的风险。为医护人员提供定量建模和分析，以帮助预防西非穿着PPC时的热应激。出汗暖体假人用于测量西非EVD响应中医护人员当前使用的5种PPC水平的热阻（Rct）和蒸发阻力（Ret）。使用预测核心体温（Tc）随服装、活动和环境而升高的数学方法来模拟PPC水平、个体体型和两种湿热条件（早晨/晚上）的不同反应。（空气温度：25°C，相对湿度：40%，平均辐射温度：35°C，风速：lm/s）和中午（30°C，60%，70°C，lm/s）。近静止空气（0.4 m/s）测量的Rct范围为0.18 - 0.26 m2 K/W，Ret范围为25.53 - 340.26 m2 Pa/W。本研究中的生物物理评估和建模为预防穿着PPC的医护人员应对西非EVD爆发的热应激提供了定量指导。
A significant number of healthcare workers have responded to aid in the relief and containment of the 2013 Ebola virus disease (EVD) outbreak in West Africa. Healthcare workers are required to wear personal protective clothing (PPC) to impede the transmission of the virus; however, the impermeable design and the hot humid environment lead to risk of heat stress. Provide healthcare workers quantitative modeling and analysis to aid in the prevention of heat stress while wearing PPC in West Africa. A sweating thermal manikin was used to measure the thermal (Rct) and evaporative resistance (Ret) of the five currently used levels of PPC for healthcare workers in the West Africa EVD response. Mathematical methods of predicting the rise in core body temperature (Tc) in response to clothing, activity, and environment was used to simulate different responses to PPC levels, individual body sizes, and two hot humid conditions: morning/evening (air temperature: 25°C, relative humidity: 40%, mean radiant temperature: 35°C, wind velocity: 1 m/s) and mid-day (30°C, 60%, 70°C, 1 m/s). Nearly still air (0.4 m/s) measures of Rct ranged from 0.18 to 0.26 m2 K/W and Ret ranged from 25.53 to 340.26 m2 Pa/W. Biophysical assessments and modeling in this study provide quantitative guidance for prevention of heat stress of healthcare workers wearing PPC responding to the EVD outbreak in West Africa.
