摘要

Objective: To describe physiological responses of mine rescuers during a simulated mine emergency. Methods: Body-worn monitors (n = 74) and core temperature (Tc) capsules (n = 54) assessed heart rate (HR), respiration rate (RR), energy expenditure (EE), oxygen consumption (V. O2), Tc and skin temperature (Tskin), by team position and task. A multivariate analysis was performed with team positions, tasks, and measures as factors. Results: HRHRmean and HRpeak were 78.6% and 94.5%, respectively, of predicted maximum heart rate. Arduous labor tasks elicited higher HR, RR, and V. O2mean than casualty care. Captains exhibited lower HRmean, HRpeak, RR, RRpeak, V. O2mean, Tc, and Tskin compared with other positions. Tc mean exceeded 38.6 8C (n = 14 recorded T c > 39 8C). Conclusions: Captains' physical loading and heat stress were lowest. Nonetheless, all tasks and positions induced high physical load and heat strain.

O2Mean而不是伤员。 与其他职位相比,船长展现出较低的HRMean,HRPeak,RR,RRPeak,V.O2mean,TC和Tskin。 TC平均值超过38.6 8℃(n = 14记录T C> 39 8c)。 结论:船长的物理载荷和热应力最低。 尽管如此,所有任务和位置诱导高物理载荷和热应变。
