Abstract

A system includes a parameter acquisition unit that receives one or more physiological parameters from one or more sensors. A memory device stores historical values of the one or more physiological parameters received by the parameter acquisition unit. A user interface unit displays representations of current and historical values of the one or more physiological parameters in a graphical user interface (GUI), wherein the GUI includes a semicircular gauge having a curved portion representing a common range of values for the one or more physiological parameters and a radial axis representing time, a center of the semicircular gauge corresponding to an earliest time for which a historical value is represented within the semicircular gauge and the curved portion corresponding to a current time. The GUI further includes a numerical representation of a current value of each physiological parameter displayed at a corresponding point along the curved portion of the semicircular gauge and a trend line for each physiological parameter originating at the center of the semicircular gauge and extending toward the curved portion thereof, wherein each trend line graphs historical values for a respective physiological parameter, and wherein a point on the trend line representing a historical value has a radial coordinate related to time and an angular coordinate related to the historical value.
