  • Patent number: 10773037
    Abstract: The present invention relates to a method for protecting a ventilation device of a ventilator against backflowing exhaled air, and to a ventilator. A respiratory gas flow is generated by a blower device and is guided via a flow connection to a breathing interface. The respiratory gas flow is adjusted with the aid of a control device to a first ventilation pressure during an inhalation phase of the patient and to a second ventilation pressure during an exhalation phase. A characteristic variable for a flow within the flow connection is detected by a device for monitoring backflowing exhaled air. A back pressure with respect to the backflowing expiratory flow is adjusted by a specific increase of the ventilation pressure taking into consideration the characteristic variable, whereby an undesirable rebreathing into the ventilation device is counteracted by the back pressure.
