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 plurality of physiological parameters from the indications;
a graphing module configured to define;
a first area of a graph comprising a normal range based on a plurality of intersection points of a first physiological parameter versus a second physiological parameter,a second area of a graph comprising a normal range based on a plurality of intersection points of a third physiological parameter versus a fourth physiological parameter, andan intersection area between the first and the second area; and
a display responsive to the graphing module to display a graph including the intersection area, the first area, and the second area.

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.

11. A method of providing an indication of a patient'"'"'s condition comprising:
-
receiving indications from a sensor at a patient monitor of a plurality of physiological parameters; processing said indications with a signal processing module to determine values for the plurality of physiological parameters from the indications; selecting a first set of value pairs (a1, a2) from the plurality of physiological parameters, wherein a1 comprises normal range values of a first physiological parameter and a2 comprises normal range values of a second physiological parameter that is different than the first physiological parameter; selecting a second set of value pairs (a3, a4) from the plurality of physiological parameters, wherein a3 comprises normal range values of a third physiological parameter and a4 comprises normal range values of a fourth physiological parameter that is different than the third physiological parameter; displaying a first graph of the first physiological parameter versus the second physiological parameter including a first area on a display, said first area based on the first set of value pairs; displaying a second graph of the third physiological parameter versus the fourth physiological parameter including a second area on the display, said second area based on the second set of value pairs; and displaying a third graph including the first area, the second area and an intersection area between the first and the second area on the display. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
