To implement small methodological changes in basic life support (BLS) training to reduce unnecessary pauses during automated external defibrillator (AED) use.
One hundred and two university students with no BLS knowledge were randomly allocated into three groups (control and 2 experimental groups). Both experimental groups received a two-hour BLS training. While the contents were identical in both groups, in one of them the reduction of no-flow time was focused on (focused no-flow group). The control group did not receive any training. Finally, all of them were evaluated in the same out-of-hospital cardiac arrest simulated scenario. The primary endpoint was the compression fraction.
Results from 78 participants were analysed (control group: 19; traditional group: 30; focused no-flow group: 29). The focused no-flow group achieved higher percentages of compression fraction (median: 56.0, interquartile rank (IQR): 53.5-58.5) than the traditional group (44.0, IQR: 42.0-47.0) and control group (52.0, IQR: 43.0-58.0) in the complete scenario. Participants from the control group performed compression-only cardiopulmonary resuscitation (CPR), while the other groups performed compression-ventilation CPR. CPR fraction was calculated, showing the fraction of time in which the participants were performing resuscitation manoeuvres. In this case, the focused no-flow group reached higher percentages of CPR fraction (77.6, IQR: 74.4-82.4) than the traditional group (61.9, IQR: 59.3-68.1) and the control group (52.0, IQR: 43.0-58.0).
Laypeople having automated external defibrillation training focused on acting in anticipation of the AED prompts contributed to a reduction in chest compression pauses during an OHCA simulated scenario.
对基础生命支持（BLS）培训实施微小的方法学改变，以减少自动体外除颤器（AED）使用过程中的不必要停顿。
102名无BLS知识的大学生被随机分为三组（对照组和两个实验组）。两个实验组均接受两小时的BLS培训。两组培训内容相同，但其中一组重点关注减少无血流时间（重点无血流组）。对照组未接受任何培训。最后，所有人员在相同的院外心脏骤停模拟场景中接受评估。主要终点是按压分数。
分析了78名参与者的结果（对照组：19名；传统组：30名；重点无血流组：29名）。在完整场景中，重点无血流组的按压分数百分比更高（中位数：56.0，四分位间距（IQR）：53.5 - 58.5），高于传统组（44.0，IQR：42.0 - 47.0）和对照组（52.0，IQR：43.0 - 58.0）。对照组参与者进行单纯胸外按压心肺复苏（CPR），而其他组进行按压 - 通气CPR。计算了CPR分数，即参与者进行复苏操作的时间比例。在这种情况下，重点无血流组的CPR分数百分比更高（77.6，IQR：74.4 - 82.4），高于传统组（61.9，IQR：59.3 - 68.1）和对照组（52.0，IQR：43.0 - 58.0）。
接受专注于根据AED提示提前行动的自动体外除颤培训后的非专业人员，有助于在院外心脏骤停模拟场景中减少胸外按压停顿。
