目的：为新手处理紧急、不熟悉任务的即时支持（jit）框架奠定基础，并对jit系统进行评估。背景：在美国，每年有超过35万人死于心脏骤停。因此，人们提倡使用自动除颤器，但不幸的是，它不能提供重要的呼吸支持。本文介绍了JITS系统框架的要素，该系统指导非专业急救人员遵循将呼吸支持与自动体外除颤器的使用相结合的治疗方案。方法：我们使用高保真病人模拟器模拟医疗紧急情况，并要求参与者照顾病人。结果：与使用JITS系统相比，使用基于纸张的NASA治疗方案时，参与者犯了更多的错误，并且需要更长的时间来稳定受伤的人。结论：这些发现证明了JITS系统在指导新手完成不熟悉的任务方面的益处。应用：JITS系统有可能改善心脏骤停患者的治疗结果。JITS框架可以应用于新手处理紧急任务而没有专门知识的许多情况。
Objective: To lay the foundation for a framework of just-in-time support (JITS) for novices dealing with urgent, unfamiliar tasks, and to evaluate a JITS system. Background: More than 350,000 people die annually of cardiac arrest in the United States. In response, automated defibrillators are advocated that, unfortunately, do not provide important respiratory support. This paper presents elements of a framework for a JITS system that instructs a lay responder to follow a treatment protocol for integrating respiratory support with the use of an automatic external defibrillator. Method: We simulated a medical emergency using a high-fidelity patient simulator and asked participants to care for the patient. Results: When using a paper-based NASA treatment protocol, participants made more errors and took longer to stabilize the injured person than when using the JITS system. Conclusion: These findings demonstrate the benefit of a JITS system to instruct novices in unfamiliar tasks. Application: The JITS system has the potential to improve the treatment outcome of victims of cardiac arrest. The JITS framework can be applied to many situations in which novices deal with urgent tasks without expertise available.
