  • Patent number: 10252013
    Abstract: A respiratory device having a respiratory gas source, a control unit and a connecting device for connecting to a respiratory mask. The control unit is connected to a sensor for detecting a measurement parameter. The control unit has a step generator for specifying a stepped modification of the pressure that is generated by the respiratory gas source. The sensor measures a signal that corresponds to the pressure distribution and is coupled to an analyzer that evaluates the temporal distribution of an analysis signal that is dependent on the measuring signal. The step generator increases the pressure by a pressure step in a respiratory cycle that follows the measuring evaluation, if the analyzer determines a deviation of the analysis signal from a limit value after a predeterminable time limit has elapsed following the pressure increase. The deviation must exceed a predeterminable minimum differential in order to trigger a pressure increase.

  • Publication number: 20110100365
    Abstract: The invention relates to a respiratory device comprising a respiratory gas source (20). a control unit (13) and a connecting device for connecting to a respiratory mask. The control unit is connected to at least one sensor (15) for detecting a measurement parameter. The inventive method controls the respiratory device. The control unit has a step generator (19) for specifying a stepped modification of the pressure that.is generated by the respiratory gas source. The sensor is configured to measure a signal that corresponds to the pressure distribution and is coupled to an analyser (18). The analyser evaluates the temporal distribution of an analysis signal that is dependent on the measuring signal and the step generator increases the pressure by a pressure step in a respiratory cycle that follows the measuring evaluation, if the analyser determines a deviation of the analysis signal from a limit value after a predeterminable time limit has elapsed following the pressure increase.
