Although the amount of clinical data available through critical care monitoring systems has steadily increased, little integration of that data occurs. Consequently, higher order relationships cannot be obtained directly. An ecological psychology approach to display design that attempts to reduce the cognitive load for the clinician by directly displaying the functional relationships between parameters is compared with a traditional approach in a monitoring and control task. Analysis of performance by Critical and Non-Critical Care Nurses and Novices suggests that the integrated display facilitates performance for all groups.
