PATIENT MONITOR INCLUDING MULTI-PARAMETER GRAPHICAL DISPLAY
First Claim
1. A system for providing an indication of a patient'"'"'s condition comprising:
- a patient monitor;
a sensor for providing the patient monitor with indications of a plurality of physiological parameters;
a signal processing module configured to determine values for the physiological parameters from the indications;
a graphing module configured to define two or more areas of a graph, each comprising a normal range for the intersection of a set of two or more of the plurality of physiological parameters, the graphing module further configured to define an intersection area of the two or more areas; and
a display configured to display a graph including the intersection area and the plurality of areas.

Abstract
A patient monitoring system and method are disclosed which provide a caregiver with more easily identifiable indications of the state of multiple physiological parameters in order to give the caregiver an indication of the patient'"'"'s overall wellness in an efficient manner. Multiple physiological parameter sets are plotted on a graph, along with an indication of each parameter set'"'"'s normal range. An overlapping area for all set'"'"'s normal ranges provides an indication of an ideal patient state. In an embodiment, alerts are generated based on parameters distance from normal readings.
