Claim 0:
1. A device for ventilating a patient, the device comprising:
a pressure source coupling for flow to a patient interface, which can be connected to the airways of a patient, and the device can be detachably connected to the patient interface;
a valve device either acting as an exhalation valve or acting as an inhalation valve, the valve device comprising a diaphragm element having a closing element, a valve drive, a pressure chamber and a control pressure chamber, wherein the valve drive is fluid communicatingly connected to the control pressure chamber for generating a control pressure in the control pressure chamber, wherein the control pressure chamber is separated from the pressure chamber by means of the diaphragm element having the closing element, wherein a first opening of the pressure chamber is opened and closed by means of the closing element and the closing element is controlled via the diaphragm element by means of the control pressure, and wherein a piezo pump acts as the valve drive, wherein the valve device when acting as the inhalation valve comprises a connection chamber belonging to the valve drive as well as a branch line element fluid communicatingly connecting the connection chamber to an outlet-side connection line element,
wherein the valve device comprises a length and a longitudinal axis that extends along the length of the valve device; wherein the closing element is axially opposite the first opening with respect to the longitudinal axis of the valve device; and
a processing unit configured to:
receive a transmission of an estimated value concerning an estimated biometric feature of the patient, wherein a body weight value concerning an estimated body weight of the patient and/or a length value concerning an estimate height of the patient are received as the estimated value concerning a biometric feature of the patient;
automatically select ventilation parameters fitting the estimated value on the basis of the estimated value; and
select, for carrying out the ventilation of the patient by means of the device, ventilation parameters.
