Abstract: A ventilator for respiration gas supply, comprising a respiration gas source, a control unit, a memory, a pressure sensor and/or a flow sensor, an exchangeable respiration gas tube, at least one connection stub for the respiration gas tube, a patient interface and a valve. The control unit is set up to use signals from the pressure sensor and/or flow sensor to ascertain the patient's respiration phase and to ascertain the patient's current tidal volume during successive inhalations and exhalations and to compare a first set volume threshold for the tidal volume with the current tidal volume and to determine whether the latter is below the former and if so, to react by driving the respiration gas source to set a second pressure for the respiration gas for inhalation and driving the respiration gas source to set the CPAP pressure for the respiration gas for exhalation.

Abstract: A system and method for supplying respiratory gas comprises a ventilation device comprising a respiratory gas source and a control device configured for generating a defined respiratory gas flow for ventilation by the ventilation device and for monitoring a parameter characteristic of a pressure by a sensor device. The parameter characterizes that pressure at which the ventilation device admits the respiratory gas stream for maintaining the defined respiratory gas flow in order to counterbalance breathing activity of the patient. The control device is configured for registering a course of the parameter over time as a pressure profile.

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.
