Survival of victims of out-of-hospital cardiopulmonary arrest (CA) is related to the time and quality of cardiopulmonary resuscitation (CPR).1 Considering that most CAs occur outside the hospital setting, it is evident that the early recognition of this condition is the cornerstone of the chain of survival. Current literature on the theme is still scarce.
To analyze categories and subcategories of words and expressions spontaneously used by laypeople during emergency calls for CA and their relationship with the recognition of this event by the medical dispatcher.
This was a cross-sectional study, with analysis of calls made by laypeople due to suspected CA to emergency medical services in Brazil. The expressions used were classified into six categories and 31 subcategories. Univariate and multivariate models were used to assess the strength of the association of categories and subcategories of words and expressions with the presumption of CA. The level of significance was set at 5%. Results: A total of 284 calls were included, and after applying the inclusion criteria, 101 calls were analyzed. The categories "cardiovascular/perfusion status" (p=0.019) and "general status" (p=0.011) were identified as confounding factors for the recognition of CA, and the subcategories "breathing difficulty" (p=0.023), "verbal unresponsiveness" (p=0.034), "facial coloration" (p=0.068) and "feeling unwell" (p=0.013) were also considered as confounders. On the other hand, the subcategories "not breathing" (p=0.010); "spatial position" (p=0.016), and "cardiovascular emergencies" (p=0.045) were identified as facilitating factors for the recognition of CA.
Categories and subcategories of expressions used by emergency callers for CA can influence the timely recognition of this condition by the medical dispatcher.
院外心肺骤停（CA）患者的存活率与心肺复苏（CPR）的时间和质量有关。1 鉴于大多数 CA 发生在医院环境之外，显然，早期识别这种情况是生存链的基石。目前关于这一主题的文献仍然很少。
分析非专业人员在 CA 急救电话中自发使用的词语和表达方式的类别和子类别，以及它们与医疗调度员对该事件的识别之间的关系。
这是一项横断面研究，对巴西紧急医疗服务机构因疑似 CA 而拨打的急救电话进行了分析。所使用的表达被分为六个类别和 31 个子类别。使用单变量和多变量模型来评估词语和表达方式的类别和子类别与 CA 假定之间的关联强度。显著性水平设为 5%。结果：共纳入 284 个电话，应用纳入标准后，分析了 101 个电话。“心血管/灌注状态”（p=0.019）和“一般状态”（p=0.011）类别被确定为 CA 识别的混杂因素，“呼吸困难”（p=0.023）、“言语无反应”（p=0.034）、“面色”（p=0.068）和“不适”（p=0.013）子类别也被认为是混杂因素。另一方面，“未呼吸”（p=0.010）、“空间位置”（p=0.016）和“心血管急症”（p=0.045）子类别被确定为 CA 识别的促进因素。
CA 急救电话中使用的词语和表达方式的类别和子类别会影响医疗调度员对该情况的及时识别。
