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.
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 pre-training, 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.
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%, <0.01; 25-54 years old: 11.8% vs. 70.6%, <0.01; 55-65 years old: 7.1% vs. 67.9%, <0.01). After three months, 26.1% of the participants aged 55-65 years successfully delivered defibrillations, which was significantly lower than that of participants aged 18-24 years (54.8%) and 25-54 years (64.3%) (=0.02). There were no differences in time measures among three age groups in each test.
The majority of untrained laypeople cannot effectively operate AEDs. More frequent training and refresher courses are crucial to improve AED skills.
自动体外除颤器（AED）使非专业人员能够对心脏骤停患者进行早期除颤，但关于普通公众使用AED能力的信息却很少。本研究评估了非专业人员操作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名年龄在18 - 65岁（18 - 24岁32人，25 - 54岁34人，55 - 65岁28人）且此前未接受过AED培训的非专业人员进行了一项前瞻性模拟研究。在培训前、培训后以及三个月随访时，使用模拟心脏骤停场景对参与者的AED技能进行单独评估。在AED操作过程中对关键操作和时间间隔进行评估。
培训前只有14名（14.9%）参与者（18 - 24岁8人，25 - 54岁4人，55 - 65岁2人）成功进行了除颤。55 - 65岁的参与者比其他年龄组更易出现AED操作失误。培训后，成功除颤的比例显著增加（18 - 24岁：25.0%对71.9%；<0.01；25 - 54岁：11.8%对70.6%；<0.01；55 - 65岁：7.1%对67.9%；<0.01）。三个月后，55 - 65岁的参与者中有26.1%成功进行了除颤，这显著低于18 - 24岁（54.8%）和25 - 54岁（64.3%）的参与者（P = 0.02）。各测试中三个年龄组在时间指标上没有差异。
大多数未经培训的非专业人员无法有效操作AED。更频繁的培训和复习课程对于提高AED技能至关重要。
