Abstract
A device and to a process supply a patient-side coupling unit () with a gas mixture. The patient-side coupling unit is connectable to a patient (Pt). A first duct (K.) guides a first gas component (air) from a first source () to a mixing point (). A second source () provides a second gas component, which is guided to a front pressure inlet (V.) of a pressure reducer (). The pressure reducer provides the second gas component (O2) at a back pressure outlet (V.). A time course of pressure at the back pressure outlet follows a time course of pressure at a reference point () in the first duct. A second duct (K.) guides the second gas component from the back pressure outlet to the mixing point. An inhalation duct (K.) guides the gas mixture from the mixing point to the patient-side coupling unit.
