Figure 4

Stem plot showing the responses entered by a subject into the GUI during the “hypovolemia” scenario. Note that the -axis scale does not have any informative value. The diamond and square red markers represent the times when state changes and alarm annunciation occur in the script. The filled circles are color coded based on the legend and show the relative times and text responses entered by subjects. The red triangles represent the average times subjects took to detect, diagnose, and treat scripted problems.
