Ventilation device (10) comprising at least one respirator (1) with at least one controllable respiratory gas source (100) and a programmable control device (21) and at least one sensor device (2) for determining the pressure and / or flow of the respiratory gas, the control device (21 ) controls the respiratory gas source to specify a first ventilation pattern (45) (with regard to pressure, flow, volume, frequency), the ventilation device having at least two further sensor devices (3, 30, 40), one sensor device (3) comprising a large number of individual sensors (3 , 3 ', 3 "...) which are designed to generate and / or measure electrical potentials and are designed to non-invasively determine the electrical impedance (EI) of a patient's lungs, the second sensor device (30) being designed to non-invasive determination of the carbon dioxide supply, the third sensor device (40) being designed for non-invasive determination The oxygen supply to the patient is characterized in that the control device (21) evaluates the sensor measured values of the EI sensor device (3) in order to determine the current ventilation (44) of the lungs during ventilation with the first ventilation pattern (45), the control device (21 ) evaluates the sensor measured values of the second sensor device (30) to determine the current carbon dioxide supply (46) and wherein the control device (21) evaluates the sensor measured values of the third sensor device 40 to determine the current (47) oxygen supply. |
