Abstract

An electronic display (10″) includes a graph representing a magnitude of a sensed physiological condition versus time. A background behind the graph is color coded delineated, such as to depict a normal range for the physiological condition and one or more abnormal ranges. This provides instant color-coded feedback to the clinician of the meaning of the graph. When a clinician selects a medication or treatment, a database is searched to generate an expectation range (42a, 42b, 42c, 42d, 44a, 46c) depicting how the sensed physiological condition is expected to move after administration of the medication or treatment. This enables the clinician to compare treatments and, after a treatment is selected, to receive easy-to-interpret feedback as to whether the sensed physiological condition is responding as expected to the treatment.
