摘要

目的消防员在灭火时使用个人防护装备。外套，以下称为标准，是个人防护装备的一部分，多年来一直没有改变。一件新外套设计得很新颖。它的内层由碳纳米管织物、两个装有冷却剂的袋子和风扇组成。新外套和标准外套将在几个指标上进行比较，包括核心体温、心率、心率变异性、热量储存、有氧能力、博格量表、热舒适量表和现场烧伤设施中的呼吸窘迫。主要结果：新大衣在所有指标上都明显优于标准大衣，只有一个例外，即热舒适量表。在p <的所有时期，被毛显著影响平均核心体温；0.0001. 它们还会影响心率p <；0.0001，心率变异性p = 0.0019，热量储存p <；0.0001.当消防员在火灾现场工作时，任何外套的一个重要任务都是确保核心体温不会达到高温水平（38°C）。新大衣在这个计数上的效果比标准大衣好，p = 0.0144。

Effectiveness of a state-of-the-art coat with fans and coolants over standard coats

Objective

Firefighters use personal protective equipment when containing fires. The coat, called standard hereafter, that is part of the personal protective equipment has not changed for many years. A new coat was designed with novel features. Its inner layer is made of a carbon nanotube-based fabric, two pouches with coolants, and fans. The new coat and standard coat were to be compared on several metrics including core body temperature, heart rate, heart rate variability, heat storage, aerobic capacity, Borg scale, Thermal Comfort scale, and Respiratory Distress in a live burn facility.

Principle results

The new coat was significantly better than the standard coat on all metrics with one exception, namely, Thermal Comfort scale. The coats significantly impact the average core body temperature across all epochs with p < 0.0001. They also impact heart rate with p < 0.0001, heart rate variability with p = 0.0019, and heat storage with p < 0.0001.

Major conclusion

One important mission for any coat was to ensure that the core body temperature does not reach the hyperthermia level temperature (38° C) when a firefighter is working inside a live burn facility. The new coat worked on this count better than the standard coat with p = 0.0144.
