A hemodynamic monitoring and control task was used to explore the utility of perceptually based displays to teach basic hemodynamic principles. The baseline display showed discrete values of key hemodynamic data elements. Alternative displays showed (a) anatomical relationships between those elements, and (b) causal constraints. Critical care nurses and student nurses used simulated "drugs" to correct simple hemodynamic disturbances using the three displays. Showing the anatomic constraints on pressure and flow improved treatment coordination by novices. Showing how etiological factors related to symptoms shortened the time required to reach a criterion level of performance and improved treatment coordination for both novices and experts.
一项血流动力学监测与控制任务被用于探究基于感知的显示器在教授基本血流动力学原理方面的效用。基线显示器展示关键血流动力学数据元素的离散值。替代显示器展示了：(a) 这些元素之间的解剖学关系，以及 (b) 因果约束。重症监护护士和实习护士使用模拟“药物”，通过这三种显示器来纠正简单的血流动力学紊乱。向新手展示压力和流量的解剖学约束可改善治疗协调性。展示病因因素与症状之间的关系缩短了达到绩效标准水平所需的时间，并改善了新手和专家的治疗协调性。
