Patent ID: 7556036

Claim:
An anesthesia process, comprising the steps of: providing a feed device for feeding at least a first anesthetic and a second anesthetic in settable quantities; providing a display; providing a data processing unit connected to the display; providing a pharmacokinetic compartment model calculation module to determine current concentrations of a first anesthetic and a second anesthetic in a plasma or at a site of action and to store concentrations of said first anesthetic and said second anesthetic continuously as a time sequence of concentration data, wherein concentration data of the first and second anesthetics predicted for at least one point in time in the future are also calculated by means of the pharmacokinetic compartment model calculation module; providing response curves for at least one anesthesia action parameter as a function of the concentrations of the first and second anesthetics; and displaying on the display at least one action diagram, in which the concentrations of the first and second anesthetics are displayed on a first axis and a second axis respectively, wherein response curves are superimposed to a system of coordinates of the first and second axis, said displaying includes displaying the sequence of the concentration data of the first and second anesthetics as a sequence of points, which are connected to one another as a trajectory, displaying a current concentration status with a symbol and displaying predicted concentration data with a separate symbol.
