背景技术背景：自动体外除颤器（AED）使外行人能够为心脏骤停的患者提供早期除颤，但关于公众使用AED的能力的信息很少。这项研究评估了外行人操作AED的能力，15分钟培训的效果，以及技能是否因年龄而异。2018年5月1日至12月31日，对94名18-65岁的非专业人员进行了前瞻性模拟研究（32名年龄在18-24岁之间，34名年龄在25-54岁之间，28名年龄在55-65岁之间），既往未接受过AED培训。参与者的AED技能分别在训练前、训练后和三个月的随访中使用模拟心脏骤停场景进行评估。在AED操作过程中的关键动作和时间间隔进行了评估。结果：只有14（14.9%）的参与者（8个年龄在18-24岁，4个年龄在25-54岁，和两个年龄在55-65岁）成功地提供除颤培训前。AED操作错误在55-65岁的参与者中比其他年龄组更容易发生。培训后，除颤成功率显著提高（18-24岁：25.0% vs. 71.9%，P
BACKGROUND: Automated external defibrillators (AEDs) enable laypeople to provide early defibrillations to patients undergoing cardiac arrest, but scant information is available on the general public's ability to use AEDs. This study assessed the ability of laypeople to operate AEDs, the effect of a 15-minute training, and whether skills differed by age.METHODS: From May 1 to December 31, 2018, a prospective simulation study was conducted with 94 laypeople aged 18-65 years (32 aged 18-24 years, 34 aged 25-54 years, and 28 aged 55-65 years) with no prior AED training. The participants' AED skills were assessed individually pretraining, post-training, and at a three-month follow-up using a simulated cardiac arrest scenario. The critical actions and time intervals were evaluated during the AED operating process.RESULTS: Only 14 (14.9%) participants (eight aged 18-24 years, four aged 25-54 years, and two aged 55-65 years) successfully delivered defibrillations before training. AED operation errors were more likely to occur among the participants aged 55-65 years than among other age groups. After training, the proportion of successful defibrillations increased significantly (18-24 years old: 25.0% vs. 71.9%, P
