PulsePoint Respond is a novel mobile device application that notifies citizens within 400 m (∼ 1/4 mile) of a suspected cardiac arrest to facilitate resuscitation. Our objectives were to (1) characterize users, and (2) understand their behavior after being sent a notification. We sought to identify challenges for optimal implementation of PulsePoint-mediated bystander resuscitation.
PulsePoint Respond users who sent a notification between 04/07/2012 and 06/16/2014 were invited to participate in an online survey. At the beginning of our study, PulsePoint Respond was active in more than 600 US communities.
There were 1274 completed surveys (response rate 1448/6777, 21.4%). Respondents were firefighters (28%), paramedics (18%), emergency medical technicians (9%), nurses (7%), MDs (1%), other health care professionals (12%), and non-health care professionals (42%). Of those who received a PulsePoint notification, only 23% (189/813) responded to the PulsePoint notification. Of those who responded, 28% (52/187) did not arrive on scene. Of those who did arrive on scene, only 32% (44/135) found a person unconscious and not breathing normally. Of those who arrived on scene prior to emergency medical services and found a cardiac arrest victim, 79% (11/14) performed bystander cardiopulmonary resuscitation.
Challenges for optimal implementation of PulsePoint Respond include technical aspects of the notifications (audio volume, precision of location information), excessive activation radii, insufficient user density in the community, and suboptimal cardiac arrest notification specificity. PulsePoint Respond has the potential to improve the community response to cardiac arrest, with 80% of responders attempting basic life support when they found a cardiac arrest victim prior to EMS.
PulsePoint Respond 是一款新型移动设备应用程序，可通知距离疑似心脏骤停患者 400 米（约 1/4 英里）范围内的公民，以促进复苏。我们的目标是：（1）描述用户特征；（2）了解他们在收到通知后的行为。我们试图确定通过 PulsePoint 实现旁观者复苏的优化实施所面临的挑战。
我们邀请在 2012 年 4 月 7 日至 2014 年 6 月 16 日之间发送通知的 PulsePoint Respond 用户参与在线调查。在我们研究开始时，PulsePoint Respond 在 600 多个美国社区中活跃。
共完成了 1274 份调查问卷（响应率为 6777 份中的 1448 份，21.4%）。受访者包括消防员（28%）、护理人员（18%）、急救医疗技术员（9%）、护士（7%）、医生（1%）、其他医疗保健专业人员（12%）和非医疗保健专业人员（42%）。在收到 PulsePoint 通知的人中，只有 23%（189/813）响应了 PulsePoint 通知。在做出响应的人中，28%（52/187）未到达现场。在到达现场的人中，只有 32%（44/135）发现有人无意识且呼吸不正常。在到达现场且在急救医疗服务之前发现心脏骤停患者的人中，79%（11/14）实施了旁观者心肺复苏术。
优化实施 PulsePoint Respond 面临的挑战包括通知的技术方面（音频音量、位置信息的精度）、过大的激活半径、社区用户密度不足以及心脏骤停通知特异性不足。PulsePoint Respond 有可能改善社区对心脏骤停的反应，有 80%的响应者在发现心脏骤停患者并在急救医疗服务到达之前尝试了基本生命支持。
