Sudden cardiac arrest (SCA) is a significant cause of adult mortality, categorized into in-hospital (IHCA) and out-of-hospital (OHCA). Survival in OHCA depends on early diagnosis, alerting Emergency Medical Service (EMS), high-quality bystander resuscitation, and prompt Automatic External Defibrillator (AED) use. Accelerating technological progress supports faster AED retrieval and use, but there are barriers in real-life OHCA situations. The study assesses 6th-year medical students' ability to locate AEDs using smartphones, revealing challenges and proposing solutions.
MATERIAL & METHODS: The study was conducted in 2022-2023 at the Medical University of Lodz, Poland. Respondents completed a survey on AED knowledge and characteristics, followed by a task to find the nearest AED using their own smartphones. As common sources did not list the University AEDs, respondents were instructed to locate the nearest AED outside the research site.
A total of 300 6th-year medical students took part in the study. Only 3.3% had an AED locating app. Only 32% of students claimed to know where the AED nearest to their home is. All 300 had received AED training, and almost half had been witness to a resuscitation. Out of the 291 medical students who completed the AED location task, the median time to locate the nearest AED was 58 s. Most participants (86.6%) found the AED within 100 s, and over half (53%) did so in under 1 min.
National registration of AEDs should be mandatory. A unified source of all AEDs mapped should be created or added to existing ones. With a median of under one minute, searching for AED by a bystander should be considered as a point in the chain of survival.
心脏骤停（SCA）是成人死亡的一个重要原因，可分为院内（IHCA）和院外（OHCA）。院外心脏骤停的存活率取决于早期诊断、呼叫紧急医疗服务（EMS）、高质量的旁观者心肺复苏以及及时使用自动体外除颤器（AED）。技术进步的加速有助于更快地获取和使用AED，但在实际的院外心脏骤停情况下仍存在障碍。本研究评估了六年级医学生使用智能手机定位AED的能力，揭示了挑战并提出了解决方案。
该研究于2022 - 2023年在波兰罗兹医科大学进行。受访者完成了一项关于AED知识和特征的调查，随后使用自己的智能手机完成一项寻找最近AED的任务。由于常见来源未列出大学的AED，受访者被要求在研究地点外寻找最近的AED。
共有三百名六年级医学生参与了该研究。只有3.3%的学生有AED定位应用程序。只有32%的学生声称知道离他们家最近的AED在哪里。所有三百名学生都接受过AED培训，近一半学生曾目睹过心肺复苏。在完成AED定位任务的291名医学生中，找到最近AED的中位时间为58秒。大多数参与者（86.6%）在100秒内找到了AED，超过一半（53%）的参与者在1分钟内找到了AED。
应强制进行AED的国家登记。应创建一个所有AED地图的统一来源，或添加到现有来源中。旁观者寻找AED的中位时间不到一分钟，应将其视为生存链中的一个环节。
