Abstract
A ventilator () ventilates a patient () by a high-flow oxygen therapy via a tube system (). The ventilator has at least one sensor element (), at least one actuatable inhalation valve or exhalation valve () and a control unit (). The sensor element is arranged and configured to determine and to output a measured variable () within the tube system. The measured variable indicates a gas flow within the tube system. The actuatable inhalation valve or exhalation valve is arranged and configured to make possible a flow of a breathing gas from a ventilation circuit () of the ventilator. The control unit regulates a ventilation pressure provided by the ventilator via the at least one sensor element and the at least one inhalation valve or exhalation valve such that a predefined maximum pressure is not exceeded in a predefined area () of the tube system.
