In a two-parted study, evaluate a new concept were mobile phone technology is used to dispatch lay responders to nearby out-of-hospital cardiac arrests (OHCAs).
Mobile phone positioning systems (MPS) can geographically locate selected mobile phone users at any given moment. A mobile phone service using MPS was developed and named Mobile Life Saver (MLS). Simulation study: 25 volunteers named mobile responders (MRs) were connected to MLS. Ambulance time intervals from 22 consecutive OHCAs in 2005 were used as controls. The MRs randomly moved in Stockholm city centre and were dispatched to simulated OHCAs (identical to controls) if they were within a 350 m distance. Real life study: during 25 weeks 1271-1801 MRs trained in CPR were connected to MLS. MLS was activated at the dispatch centre in parallel with ambulance dispatch when an OHCA was suspected. The MRs were dispatched if they were within 500 m from the suspected OHCA.
Simulation study: mean response time for the MRs compared to historical ambulance time intervals was reduced by 2 min 20s (44%), p<0.001, (95% CI, 1 min 5s - 3 min 35s). The MRs reached the simulated OHCA prior to the historical control in 72% of cases. Real life study: the MLS was triggered 92 times. In 45% of all suspected and in 56% of all true OHCAs the MRs arrived prior to ambulance. CPR was performed by MRs in 17% of all true OHCAs and in 30% of all true OHCAs if MRs arrived prior to ambulance.
Mobile phone technology can be used to identify and recruit nearby CPR-trained citizens to OHCAs for bystander CPR prior to ambulance arrival.
在一项两部分的研究中，评估一种新的概念，即利用移动电话技术派遣非专业救援人员到附近的院外心脏骤停（OHCA）现场。
移动电话定位系统（MPS）可以在任何给定时刻定位选定的移动电话用户的地理位置。开发了一种使用 MPS 的移动电话服务，并将其命名为移动救生员（MLS）。模拟研究：25 名名为移动响应者（MRs）的志愿者与 MLS 连接。2005 年连续 22 例 OHCA 的救护车时间间隔用作对照。MRs 在斯德哥尔摩市中心随机移动，如果他们在 350 米的距离内，则被调度到模拟的 OHCA（与对照相同）。现实生活研究：在 25 周的时间里，有 1271-1801 名接受过心肺复苏培训的 MRs 与 MLS 连接。当怀疑发生 OHCA 时，MLS 在调度中心与救护车调度同时激活。如果 MRs 在疑似 OHCA 地点 500 米范围内，将对其进行调度。
模拟研究：与历史救护车时间间隔相比，MRs 的平均响应时间缩短了 2 分 20 秒（44%），p<0.001，（95%CI，1 分 5 秒-3 分 35 秒）。在 72%的情况下，MRs 在历史对照之前到达模拟 OHCA。现实生活研究：MLS 触发了 92 次。在所有疑似和 56%的真实 OHCA 中，MRs 先于救护车到达。在所有真实 OHCA 中，MRs 进行了 17%的 CPR，如果 MRs 先于救护车到达，则进行了 30%的 CPR。
移动电话技术可用于识别和招募附近接受过心肺复苏培训的公民，以便在救护车到达之前对院外心脏骤停进行旁观者 CPR。
