The major objective was to assess the time period from a witnessed ventricular fibrillation (VF) to the first defibrillation (DEF) in a simulated manikin scenario, while the minor objective was to analyze the most common errors that occurred during DEF and the maintenance of 2-min intervals during resuscitation. We examined 210 students (medical faculty students, MF; and paramedic faculty students, PF) who had to treat a patient with VF. In the study we used the Laerdal(®) Training Manikin and the Zoll M Series(®) defibrillator. The mean time period from the witnessed VF to the first DEF was 50.1 s (SD 32.5 s) in the MF group and 62.9 s (SD 36.9 s) in the PF group (no statistically significant difference). The delay resulted from the lack of constant ECG monitoring and charging in the option "Monitor" instead of the option "Defibrillation." The PF group shortened the 2-min cycles between defibrillations. The problems observed during the study were technical and educational. We concluded that the option "Monitor" should be removed from the equipment because it seems to be redundant. The teaching problems were a lack of constant ECG monitoring, incorrect handling of the defibrillator, and not keeping to 2-min loops of CPR.
主要目标是评估在模拟人体模型场景中从目击心室颤动 (VF) 到首次除颤 (DEF) 的时间间隔，次要目标是分析在 DEF 过程中最常见的错误以及在复苏过程中保持 2 分钟间隔的错误。我们检查了 210 名学生（医学系学生，MF；和急救系学生，PF），他们必须治疗 VF 患者。在研究中，我们使用了 Laerdal(®) 训练模型和 Zoll M Series(®) 除颤器。MF 组从目击 VF 到首次 DEF 的平均时间间隔为 50.1s（SD 32.5s），PF 组为 62.9s（SD 36.9s）（无统计学差异）。延迟是由于在“Monitor”选项中而不是在“Defibrillation”选项中缺少持续 ECG 监测和充电造成的。PF 组缩短了两次除颤之间的 2 分钟循环。研究中观察到的问题是技术和教育方面的。我们得出结论，应从设备中删除“Monitor”选项，因为它似乎是多余的。教学问题是缺乏持续的 ECG 监测、除颤器使用不当以及不遵守 2 分钟的 CPR 循环。
