Bystander cardiopulmonary resuscitation (CPR) is an important determinant of survival from out-of-hospital cardiac arrest (OHCA), yet rates of bystander CPR are highly variable. In an effort to promote bystander CPR, the procedure has been streamlined, and ultrashort teaching modalities have been introduced. CPR has been increasingly reconceptualized as simple, safe, and easy to perform; however, current methods of CPR instruction may not adequately prepare lay rescuers for the various logistical, conceptual, and emotional challenges of resuscitating a victim of cardiac arrest.
We adopted a constructivist grounded theory methodology to qualitatively explore bystander CPR and invited lay rescuers who had recently (ie, within 1 week) intervened in an OHCA to participate in semistructured interviews and focus groups. We used constant comparative analysis until theoretical saturation to derive a midrange explanatory theory of bystander CPR. We constructed a 3-stage theoretical model describing a common experiential process for lay rescuer intervention in OHCA: Being called to act is disturbing, causing panic, shock, and disbelief that must ultimately be overcome. Taking action to save the victim is complicated by several misconceptions about cardiac arrest, where victims are mistakenly believed to be choking, and agonal respirations are misinterpreted to mean the victim is alive. Making sense of the experience is challenging, at least in the short term, where lay rescuers have to contend with self-doubt, unanswered questions, and uncomfortable emotional reactions to a traumatic event.
Our study suggests that current CPR training programs may not adequately prepare lay rescuers for the reality of an OHCA and identifies several key knowledge gaps that should be addressed. The long-term psychological consequences of bystander intervention in OHCA remain poorly understood and warrant further study.
旁观者心肺复苏术(CPR)是院外心脏骤停(OHCA)患者生存的重要决定因素,但旁观者实施心肺复苏术的比例差异很大。为了推广旁观者心肺复苏术,该操作流程已得到简化,并引入了超短教学模式。心肺复苏术已越来越多地被重新定义为简单、安全且易于实施;然而,当前的心肺复苏术教学方法可能无法让非专业救援人员充分应对复苏心脏骤停患者时面临的各种后勤、概念和情感挑战。
我们采用建构主义扎根理论方法对旁观者心肺复苏术进行定性研究,并邀请最近(即1周内)参与院外心脏骤停急救的非专业救援人员参加半结构化访谈和焦点小组讨论。我们使用持续比较分析,直至达到理论饱和,以得出关于旁观者心肺复苏术的中程解释理论。我们构建了一个三阶段理论模型,描述非专业救援人员参与院外心脏骤停急救的常见体验过程:被召唤采取行动令人不安,会引发恐慌、震惊和怀疑,而这些最终都必须克服。采取行动救助患者因对心脏骤停的一些误解而变得复杂,比如错误地认为患者是噎食,将濒死呼吸误解为患者还活着。理解这一经历具有挑战性,至少在短期内如此,非专业救援人员必须应对自我怀疑、未解决的问题以及对创伤性事件的不适情绪反应。
我们的研究表明,当前的心肺复苏培训项目可能无法让非专业救援人员充分应对院外心脏骤停的实际情况,并识别出了几个应予以解决的关键知识空白。旁观者参与院外心脏骤停急救的长期心理后果仍知之甚少,值得进一步研究。
