Ventilation device (10), comprising at least one ventilator (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) (in terms of pressure, flow, volume, frequency), the ventilation device having at least two further sensor devices (3, 30, 40), one sensor device (3) having a large number of individual sensors (3 , 3', 3"...) which are designed to generate and/or measure electrical potentials and to non-invasively determine the electrical impedance (EI) of a patient's lungs, the second sensor device (30) being designed for non-invasive determination of the carbon dioxide supply, wherein the third sensor device (40) is designed for non-invasive determination ung of the patient's oxygen supply, characterized in that the control device (21) evaluates the sensor readings of the EI sensor device (3) to determine the instantaneous ventilation (44) of the lungs during ventilation with the first ventilation pattern (45), the control device (21 ) the sensor readings of the second sensor device (30) to determine the instantaneous carbon dioxide supply (46) and wherein the control device (21) evaluates the sensor readings of the third sensor device 40 to determine the instantaneous (47) oxygen supply. |
