Abstract

Introduction: Lightweight shelters made of water- and windproof polyester are frequently used by mountain rescue, but information on physical and psychological stress during their use is scarce.

Methods: A prospective observational study was conducted with 48 experienced rescuers who performed cardiopulmonary resuscitation training on a manikin in a shelter in alpine terrain. The objective parameters of air temperature, moisture, and concentrations of carbon dioxide and oxygen were measured inside the shelter. The subjective experience of the rescuers regarding stress, moisture, noise, air draft, convenience, spatial confinement, brightness, room temperature, and air quality was assessed using a questionnaire.

Results: During 15 min of cardiopulmonary resuscitation, the median temperature in the shelter rose by >15°C (Δt, 15.9°C; interquartile range, 14.3-16.5°C; P=0.018). Carbon dioxide concentrations increased to 0.97 vol% maximum. Bag valve mask ventilation was established with and without the use of supplemental oxygen, which showed significantly different oxygen shelter concentrations (21.1 vol% with oxygen, 20.6 vol% without oxygen; P<0.001). Most participants rated the physical comfort and spatial conditions inside the shelter as convenient.

Conclusions: In this study, the use of shelters in alpine terrain improved physical comfort while carrying out a rescue. Most participants gave high ratings for the working conditions in the shelter.

高山救援中的避难所：他们能在部署地点创造一个舒适的区域吗？

简介：由防水和防风聚酯制成的轻型庇护所经常用于山地救援，但有关其使用过程中身体和心理压力的信息很少。方法：对48名经验丰富的救援人员进行前瞻性观察研究，这些救援人员在高山地形的避难所对人体模型进行心肺复苏训练。在庇护所内测量了空气温度、湿度、二氧化碳和氧气浓度等客观参数。通过问卷调查对救援人员在压力、湿度、噪音、通风、便利性、空间限制、亮度、室温和空气质量等方面的主观体验进行评估。结果：心肺复苏15 min时，遮蔽室内中位温度升高15.9°C (Δt, 15.9°C；四分位间距14.3-16.5°C；P = 0.018)。二氧化碳浓度最高可达0.97 vol%。在有氧和无氧情况下建立袋阀面罩通气，氧遮蔽浓度差异显著(有氧21.1%，无氧20.6%；结论：在本研究中，在高山地形中使用掩体可以提高救援人员在进行救援时的身体舒适度。大多数参与者对收容所的工作条件给予了很高的评价。

期刊介绍： Wilderness & Environmental Medicine, the official journal of the Wilderness Medical Society, is the leading journal for physicians practicing medicine in austere environments. This quarterly journal features articles on all aspects of wilderness medicine, including high altitude and climbing, cold- and heat-related phenomena, natural environmental disasters, immersion and near-drowning, diving, and barotrauma, hazardous plants/animals/insects/marine animals, animal attacks, search and rescue, ethical and legal issues, aeromedial transport, survival physiology, medicine in remote environments, travel medicine, operational medicine, and wilderness trauma management. It presents original research and clinical reports from scientists and practitioners around the globe. WEM invites submissions from authors who want to take advantage of our established publication''s unique scope, wide readership, and international recognition in the field of wilderness medicine. Its readership is a diverse group of medical and outdoor professionals who choose WEM as their primary wilderness medical resource.
