The invention relates to a method and a method (20) for high-frequency ventilation of a patient, wherein by means of a (12) connected to a pressure source (12) and arranged close to the patient device (20) for high-frequency ventilation of a patient short pressure pulses (42) with a Duration of less than 200 ms for the high-frequency ventilation, wherein the pressure pulses (42) are generated by, for example, by means of a control device (50) at least one of a sensor (24) of the patient module (20) available sensor signal (56, 58) is compared with at least one variable threshold value (44, 46) and, depending on the result of the comparison, at least one control signal (60, 62) for controlling at least one valve (26, 28) of the patient module (20) is generated.
