DESCRIPTION (provided by applicant): Adverse physiological events occur frequently in critically ill patients and often lead to catastrophic outcomes. Technological improvements in monitoring displays have the potential to enhance nursing performance and patient outcomes by allowing nurses to better visualize the hemodynamic status of their patients. This study will explore the application of graphical display technology in the critical care environment. The goal is to determine whether a new graphical display for hemodynamic monitoring improves critical care nurses' ability to detect, identify, and manage adverse physiological events in critically ill patients. Bioengineering and human factors research suggests that presenting complex information graphically is more intuitive than waveform or numerical representation. Phase 1 of this research will involve adapting a graphical cardiovascular display that was originally designed for use in operating rooms. Display adaptation to critical care nursing will be an iterative process, guided by an established design refinement protocol. Phase 2 will evaluate the effects of this display on critical care nurses' ability to detect changes in hemodynamic status, correctly identify adverse physiologic events, and initiate appropriate nursing interventions. Using a full-scale patient simulator, performance and cognitive workload for nurses using the adapted graphical display will be compared to those using a traditional monitoring display.

描述（由申请人提供）：不良生理事件经常发生在危重患者中，通常会导致灾难性结局。监测显示器的技术改进有可能通过允许护士更好地可视化其患者的血流动力学状态来提高护理性能和患者结局。本研究将探讨图形显示技术在重症监护环境中的应用。目的是确定用于血流动力学监测的新图形显示是否提高了重症监护护士检测、识别和管理危重患者不良生理事件的能力。生物工程和人为因素研究表明，以图形方式呈现复杂信息比波形或数字表示更直观。这项研究的第一阶段将涉及调整最初设计用于手术室的图形心血管显示。重症监护护理的显示适应将是一个迭代过程，由既定的设计优化方案指导。第2阶段将评估该显示对重症监护护士检测血流动力学状态变化、正确识别不良生理事件和启动适当护理干预的能力的影响。使用全尺寸患者模拟器，将使用适配的图形显示器的护士的性能和认知工作量与使用传统监测显示器的护士进行比较。
