Sudden cardiac arrest (SCA) remains a significant cause of morbidity and mortality, and the key to increased survival is emergent bystander intervention. A growing body of evidence has shown that timely bystander-initiated cardiopulmonary resuscitation (CPR) and defibrillation are significantly correlated with an increased likelihood of survival. Despite these demonstrated benefits, bystanders perform these interventions in less than half of witnessed SCA cases. We hypothesized that the level of public CPR and automated external defibrillator (AED) knowledge may be limited and may play a role in the likelihood of intervening.
A convenience survey of potential bystanders to SCA was conducted in a high-traffic shopping center to estimate the overall knowledge level of CPR and AED usage and determine general attitudes toward intervening in the setting of SCA. Concurrently with the survey, professional emergency responders offered free bystander compression-only CPR and AED training on location.
The majority of survey respondents expressed a willingness to perform the aforementioned interventions when asked directly. Results, however, indicate that although 69% of respondents consider themselves to have a general knowledge of CPR, only 18% spontaneously mentioned CPR when presented with a hypothetical SCA scenario. In addition, only 2.2% mentioned defibrillation, and 63% indicated that they would not know how to locate a public access AED when needed. Of the individuals who participated in both the survey and the training, all of them indicated that they were more likely to intervene in an SCA after receiving the training.
Our findings suggest that future public outreach efforts should target the current CPR and AED knowledge gap. They also indicate that free, brief trainings offered at public events are a feasible way to increase the knowledge and skills of potential bystanders to SCA.
心脏骤停（SCA）仍然是发病和死亡的重要原因，提高生存率的关键是旁观者紧急干预。越来越多的证据表明，旁观者及时启动心肺复苏（CPR）和除颤与生存率提高显著相关。尽管有这些已证实的益处，但在不到一半的目击SCA病例中，旁观者会进行这些干预。我们假设公众对CPR和自动体外除颤器（AED）的知识水平可能有限，这可能影响干预的可能性。
在一个人流量大的购物中心对SCA潜在旁观者进行了一项便利调查，以评估CPR和AED使用的总体知识水平，并确定对在SCA情况下进行干预的一般态度。在调查的同时，专业急救人员在现场提供免费的旁观者仅按压式CPR和AED培训。
大多数调查受访者在被直接询问时表示愿意进行上述干预。然而，结果表明，虽然69%的受访者认为自己对CPR有一般了解，但在面对假设的SCA场景时，只有18%的人自发提到了CPR。此外，只有2.2%的人提到了除颤，63%的人表示他们不知道在需要时如何找到公共可及的AED。参与调查和培训的所有人都表示，接受培训后他们更有可能在SCA中进行干预。
我们的研究结果表明，未来的公众宣传工作应针对当前CPR和AED知识差距。研究结果还表明，在公共活动中提供免费的简短培训是提高SCA潜在旁观者知识和技能的可行方法。
