Abstract: The invention relates to an appliance for performing anaesthesia or analgosedation, comprising a dosing device (5) for the intravenous administration of an adjustable dose of at least one anaesthetic to a patient (1), a measuring device (2) for determining the concentration of the at least one anaesthetic in the exhaled air of the patient (1), means (4) for determining the effect of the at least one anaesthetic on the patient (1), preferably in the form of a depth of anaesthesia or depth of analgosedation, and a data processing device (7), which communicates via interfaces with the dosing device (5), the measuring device (2) and the means (4) for determining the effect and which, on the basis of the determined values of the parameters dosage, concentration and effect of the at least one anaesthetic, establishes a pharmacological model individualized to the patient (1) and, using the individualized pharmacological model that is established, calculates an individual dosage, optimized to the patient (1), of the

Abstract: A solution is supposed to be created with a method for generating positively and/or negatively ionized gas analytes for gas analysis in an ion mobility spectrometer or in a mass spectrometer, with which method the gas analyte can be ionized without the restrictions of previous ionization methods for gas analysis in an ion mobility spectrometer or in a mass spectrometer, forming positive and/or negative ions. This is achieved in that the positive and/or negative gas ions are generated by means of a plasma, which is brought about by means of a dielectrically inhibited discharge, whereby the dielectrically inhibited discharge is produced in that a noble gas is passed in through a capillary made of a dielectric material, whereby an alternating voltage is applied by means of two electrically insulated electrodes disposed on the capillary adjacent to the exit region of the capillary, and the gas analyte is passed to the exit region outside of the capillary.
