介绍公共接入除颤使院外心脏骤停（OHCA）后神经系统完好存活的机会增加一倍。尽管社区中有越来越多的自动体外除颤器（AED），但尽管经常可用，但很少使用。我们的目的是匹配OHCAs与已知的AED的位置，以了解AED的可用性，减少AED的可用性在夜间和业务半径的影响，他们可以有效地retrieval.Methods所有紧急呼叫中南救护车服务2014年4月至2016年4月进行筛选，以确定心脏骤停。每个人都被映射到最近的AED，根据一天中的时间。映射软件被用来计算每个OHCA和相应的AED之间的旁观者的实际步行距离，当以轻快的步行速度（4 mph）旅行时。所有AED在白天可用，但只有713（34.3%）在夜间可用。5.91%的心脏骤停发生在白天100米的检索（步行）半径内，下降到1.59%。农村AED使用距离大于城市（P
Introduction Public access defibrillation doubles the chances of neurologically intact survival following out-of-hospital cardiac arrest (OHCA). Although there are increasing numbers of defibrillators (automated external defibrillator (AEDs)) available in the community, they are used infrequently, despite often being available. We aimed to match OHCAs with known AED locations in order to understand AED availability, the effects of reduced AED availability at night and the operational radius at which they can be effectively retrieved.Methods All emergency calls to South Central Ambulance Service from April 2014 to April 2016 were screened to identify cardiac arrests. Each was mapped to the nearest AED, according to the time of day. Mapping software was used to calculate the actual walking distance for a bystander between each OHCA and respective AED, when travelling at a brisk walking speed (4 mph).Results 4012 cardiac arrests were identified and mapped to one of 2076 AEDs. All AEDs were available during daytime hours, but only 713 at night (34.3%). 5.91% of cardiac arrests were within a retrieval (walking) radius of 100 m during the day, falling to 1.59% out-of-hours. Distances to rural AEDs were greater than in urban areas (P
