1. a system that is configured to detect the mouth breathing in early stage expiration during the breathing that relates to pressure support device is disposed, described system comprises:

  • Pressure generator (14), it is configured to generate the pressurized stream of the energy breathing gas for sending to experimenter'"'"'s air flue;

    Sensor (20), it is configured to provide the output signal of passing on the information that relates to the described one or more parameters of pressurized stream when being delivered to described experimenter'"'"'s described air flue that can breathing gas;

    AndOne or more processors (24), it is configured to move computer program module, and described computer program module comprises;

    Parameter module (31), it is configured to determine the described one or more parameters of pressurized stream when being delivered to described experimenter'"'"'s described air flue that can breathing gas based on described output signal, described one or more parameters comprise the first parameter;

    Spirography module (34), it is configured to described one or more parameters based on being determined by described parameter module and estimates described experimenter'"'"'s the expiratory phase of breathing and the transition between expiration phase;

    Parameter extreme value module (36), it is configured to identify the local extremum of the level of described the first parameter during described experimenter'"'"'s the given expiration phase of breathing;

    AndMouth breathing detection module (38), it is configured to by the described level of described the first parameter of the time that depends in analytical sampling window, determine that whether described experimenter is by mouth breathing during described given expiration phase, described sampling window starts from or approaches the local extremum of the described level of described the first parameter of identifying.
