Method to assess anesthesia
First Claim
1. A method for displaying a general state of anesthesia of a patient as a multi-variable function comprising the steps of:
- determining a first and a second range, wherein the first range is associated with a first vital sign and second range is associated with a second vital sign;
monitoring the first and the second vital signs;
determining a general state of the patient from the monitored first and second vital signs; and
displaying an indicator corresponding to the general state of anesthesia of the patient as a multi-variable plot having the first vital sign as a variable on a first variable on a first axis and the second vital sign as a variable on a second axis.

Abstract
A patient'"'"'s general state of anesthesia is displayed as a Cartesian plot of two vital signs: heart rate and blood pressure, in a window on a monitor. The heart rate is plotted on the x-axis while blood pressure is plotted on the y-axis. An anesthetist selects minimum and maximum values for each vital sign which are appropriate for the patient. These limits denote a desired zone which is indicated on the display. As the heart rate and the blood pressure are monitored, the general state is shown as an indicator on the plot as a multi-variable function of the two vital signs. When the indicator is within the desired zone, the two vital signs are in an acceptable range. When the indicator is outside of the desired zone, a visual or audible alarm indicates potential patient distress.
