Ventilator for high-flow oxygen therapy

A ventilation system for ventilating a patient by a high-flow oxygen therapy, the ventilation system comprising:

• a tube system comprising an inhalation tube and an exhalation tube
• a ventilator comprising:
• a sensor device comprising at least one a 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 inhalation valve or an exhalation valve, the actuatable valve configuration being arranged and configured to make possible a flow of a breathing gas out of a ventilation circuit of the ventilator;
• and
• 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, wherein the tube system is connected to the ventilator for providing the ventilation circuit.

A process for regulating a ventilation pressure provided by a ventilator during a high-flow oxygen therapy via a tube system, the process comprising the steps of:

• providing an actuatable valve configuration comprising at least one actuatable inhalation valve or actuatable exhalation valve for making possible a flow of a breathing gas of a ventilation circuit of the ventilator;
• determining and outputting a measured variable within the tube system, wherein the measured variable indicates a gas flow within the tube system;
• and
• regulating a ventilation pressure provided by the ventilator via the at least one actuatable valve configuration such that a predefined maximum pressure is not exceeded in a predefined area of the tube system.
