1. A ventilator for ventilating a patient by a high-flow oxygen therapy via a tube system providing at least a portion of a ventilation circuit of the ventilator, the ventilator comprising:
a sensor device comprising at least one sensor element, the sensor device being arranged and configured to determine and to output a measured variable within the tube system, wherein the measured variable indicates a gas flow within the tube system;
an actuatable valve configuration comprising at least one of an actuatable inhalation valve or an actuatable exhalation valve, the actuatable valve configuration being arranged and configured to make possible a flow of a breathing gas out of the ventilation circuit of the ventilator;
a control unit configured to regulate a ventilation pressure provided by the ventilator via the sensor device and the actuatable valve configuration such that a predefined maximum pressure is not exceeded in a predefined area of the tube system; and
a blower, wherein the control unit carries out the regulation of the ventilation pressure exclusively via the actuatable valve configuration without changing a blower output of the blower.
