Although the importance of bystander cardiopulmonary resuscitation has been shown in multiple studies, the rate of bystander cardiopulmonary resuscitation is still relatively low in many countries. Little is known on bystanders' perceptions influencing the decision to start cardiopulmonary resuscitation. Our study aims to determine such factors.
Semi-structured telephone interviews with bystanders of out-of-hospital cardiac arrests between December 2014 and April 2016 were performed in a prospective manner. This single-center survey was conducted in the city of Münster, Germany. The bystander's sex and age, the perception of the victim's breathing and initial condition were correlated with the share of bystander cardiopulmonary resuscitation in the corresponding group.
101 telephone interviews were performed with 57 male and 44 female participants showing a mean age of 52.7 (SD ± 16.3). In case of apnoea 38 out of 46 bystanders (82.6%) started cardiopulmonary resuscitation; while in case of descriptions indicating agonal breathing 19 out of 35 bystanders (54.3%) started cardiopulmonary resuscitation (p = .007). If the patient was found unconscious 47 out of 63 bystanders (74.7%) performed cardiopulmonary resuscitation, while in cases of witnessed cardiac arrest 19 out of 38 bystanders (50%) attempted cardiopulmonary resuscitation (p = .012). Witnessed change of consciousness is an independent factor significantly lowering the probability of starting cardiopulmonary resuscitation (regression coefficient -1.489, p < .05).
The witnessed loss of consciousness was independently associated with a significant reduction in the likelihood that bystander-CPR was started. These data reinforce the importance of teaching the recognition of early cardiac arrest.
尽管多项研究已经证明旁观者心肺复苏的重要性，但在许多国家，旁观者心肺复苏的比例仍然相对较低。关于影响旁观者开始心肺复苏决策的因素知之甚少。我们的研究旨在确定这些因素。
2014 年 12 月至 2016 年 4 月，以前瞻性方式对院外心脏骤停的旁观者进行了半结构化电话访谈。这项单中心调查在德国明斯特市进行。将旁观者的性别和年龄、对受害者呼吸和初始状况的感知与相应组中旁观者心肺复苏的比例相关联。
对 57 名男性和 44 名女性旁观者进行了 101 次电话访谈，平均年龄为 52.7（标准差±16.3）。在出现呼吸暂停的情况下，46 名旁观者中有 38 名（82.6%）开始心肺复苏；而在描述濒死样呼吸的情况下，35 名旁观者中有 19 名（54.3%）开始心肺复苏（p=0.007）。如果患者被发现意识丧失，63 名旁观者中有 47 名（74.7%）进行心肺复苏，而在目击心脏骤停的情况下，38 名旁观者中有 19 名（50%）尝试心肺复苏（p=0.012）。目击意识改变是独立降低开始心肺复苏概率的因素（回归系数-1.489，p<0.05）。
目击者意识丧失与旁观者心肺复苏开始的可能性显著降低有关。这些数据强调了教授识别早期心脏骤停的重要性。
