Process and device for monitoring a patient

1. A process for monitoring at least one parameter of a patient, the process comprising the steps of:

providing a monitoring means for monitoring an anesthetic concentration of a patient undergoing anesthesia, said monitoring means has at least one display for the simultaneous display of a plurality of parameter values for an anesthetic parameter at different points in time, said display providing a set of axes and showing all of said plurality of parameter values plotted as one of a line and a set of points with respect to the axes in a same scale;

selecting at least one parameter value from the plurality of parameter values, said at least one parameter value being one of a line portion and a point of said set of points, said one of said line portion and said point having line or point characteristics different from line or point characteristics of adjacent line portions or points.

2. A process in accordance with claim 1 , further comprising the step of selecting at least one parameter range which is displayed in a manner of display that differs from the manner of display of the non-selected parameter ranges.

3. A process in accordance with claim 2 , wherein said step of selecting at least one parameter value includes displaying the selected parameter value with a lighter contrast and said step of selecting at least one parameter range includes displaying the selected parameter range with a lighter contrast.

4. A process in accordance with claim 1 , further comprising selecting at least two parameter values, which are displayed in different manners from one another.

5. A process in accordance with claim 2 , wherein the at least one parameter range is a parameter range between at least two TOL or TOSS isoboles.

6. A process in accordance with claim 2 , further comprising receiving an input from an operator to modify the at least one parameter range on said display on the basis of an observation made during the monitoring.

7. A device for monitoring a parameter of a patient, the device comprising:

a monitoring device for monitoring an anesthetic concentration of a patient undergoing anesthesia, said monitoring means including a display means for the simultaneous display of a plurality of parameter values for an anesthetic parameter at different points in time, said display means showing all of said plurality of parameter values as one of a line and a set of points with respect to the axes in a continuous order; and

selecting means for selecting at least one parameter value, from the plurality of parameter values, said one parameter value being one of a line portion and a point of said set of points, said one of said line portion and said point having line or point characteristics different from line or point characteristics of adjacent line portions or points.

8. A device in accordance with claim 7 , further comprising a means for selecting at least one parameter range, which is displayed in a manner of display that differs from the manner of display of the non-selected parameter ranges.

9. A device in accordance with claim 7 , wherein said selecting means is for selecting at least two parameter values, which are displayed in different manners from one another.

10. A device in accordance with claim 8 , further comprising input means for receiving input from an operator to modify the at least one parameter range of said display means on the basis of observation made during the monitoring.

11. A device in accordance with claim 7 , further comprising an anesthesia apparatus connected to said monitoring device, said anesthesia apparatus providing said monitoring device with said plurality of parameter values, said parameter values being individual concentrations of first and second anesthetics.

12. A process for monitoring at least one parameter of a patient, the process comprising the steps of:

providing a monitoring means for monitoring an anesthetic concentration of a patient undergoing anesthesia, said monitoring means has at least one display for the simultaneous display of a plurality of parameter values of an anesthetic parameter at different points in time, said anesthetic parameter being an anesthetic action parameter formed by a concentration of first and second anesthetics, said display displaying an action diagram which plots a concentration of said first anesthetic on a first axis, and plots a concentration of said second anesthetic on a second axis, said display including a plurality of curves indicating anesthetic isoboles in said action diagram;

selecting at least one parameter range which is displayed in a manner of display that differs from the manner of display of the non-selected parameter ranges, said step of selecting at least one parameter range includes displaying the selected parameter range with a lighter contrast a range display characteristic that is different from a range display characteristic of adjacent ranges, said range being between two of said isoboles in said action diagram.

13. A device for monitoring a parameter of a patient, the device comprising:

a monitoring device for monitoring an anesthetic concentration of a patient undergoing anesthesia, said monitoring means including a display means for the simultaneous display of a plurality of parameter values of an anesthetic parameter at different points in time, said display means displaying an action diagram which plots a concentration of said first anesthetic on a first axis, and plots a concentration of said second anesthetic on a second axis, said action diagram including a plurality of curves indicating anesthetic isoboles in said action diagram; and

selecting means for selecting at least one parameter range between two of said isoboles in said action diagram, said one parameter is range being displayed with a range display characteristic that is different from a range display characteristic of adjacent ranges.
