An anesthetic breathing apparatus has a processing unit, a breathing circuit for providing an inspiratory patient gas mixture of re-breathed gas and/or fresh gas to a patient fluidly connected to the breathing circuit, and a fresh gas supply controllable by the processing unit for supplying a flow of the fresh gas to the breathing circuit in a composition including oxygen and at least one anesthetic agent (AA). A user interface includes a first user input element for receiving operator input for an anesthetic target value including an end expiratory concentration of the AA (EtAA) target value and/or an end expiratory minimum alveolar concentration (EtMAC) target value of an end expiratory MAC value of the patient, and a second user input element for receiving operator input for a desired control profile for the fresh gas supply for obtaining at least the anesthetic target value. The inspiratory patient gas mixture is controlled based on at least the anesthetic target value, the oxygen target value, and the desired control profile.
