Emergency room personnel are threatened by secondary poisoning when treating victims affected by chemical warfare agents. Therefore, resuscitation skills practised with respiratory protection equipment in place require evaluation. We investigated the influence of wearing air-purifying respirators on the simulated resuscitation of chemical warfare agent casualties. We studied 22 anaesthetic trainees in a simulated resuscitation scenario requiring five set tasks, either unprotected, wearing a binocular visor respirator or a panoramic visor respirator in a randomised, crossover study. Treatment times did not differ between the three groups, with mean (SD) times to complete the tasks being 122 (8) s without a mask, 126 (7) s when wearing the panoramic visor mask and 129 (8) s when wearing the binocular respirator mask. All anaesthetists preferred the panoramic visor in terms of visual orientation but 88% of them rated the binocular mask as being more comfortable. Modern respirators have a negligible effect on simulated resuscitation scenarios for victims affected by chemical warfare agents. Panoramic visor respirators allow better visual orientation for anaesthetists during simulated resuscitation.
急诊室工作人员在治疗化学战剂中毒受害者时会受到二次中毒的威胁。因此，在佩戴呼吸防护设备的情况下进行复苏技能培训需要进行评估。我们调查了佩戴空气净化呼吸器对化学战剂伤亡人员模拟复苏的影响。在一项随机交叉研究中，我们让22名麻醉学员在模拟复苏场景中完成五项设定任务，分别是不佩戴防护装备、佩戴双目面罩呼吸器或全景面罩呼吸器。三组之间的治疗时间没有差异，完成任务的平均（标准差）时间分别为：不戴口罩时为122（8）秒，佩戴全景面罩时为126（7）秒，佩戴双目呼吸器面罩时为129（8）秒。所有麻醉师在视觉方向方面更喜欢全景面罩，但88%的人认为双目面罩更舒适。现代呼吸器对化学战剂中毒受害者的模拟复苏场景影响可忽略不计。全景面罩呼吸器在模拟复苏过程中能让麻醉师有更好的视觉方向。
