ABSTRACT:
An interactive respiratory regulator comprising a recording device recording the respiratory pattern of a user and issuing a corresponding respiratory signal, an instruction signal generator for the generation of an instruction signal that can be perceived by the user in order to influence his respiratory behavior, a control device controlling the instruction signal generator, a processing device which determines by means of a parameter of the respiratory signal received, whether the recorded respiratory pattern during a predetermined time span meets a pre-adjustable standard for this parameter, and which at a certain error percentage sends a starting signal to the control device. The interactive respiratory regulator is characterized in that the processing device processes as parameter the ratio between the in- and exhalation time in a respiratory cycle. In a preferred embodiment the processing device includes the frequency of the respiratory cycles as second parameter and the pre-adjustable standard comprises also a value for this parameter.
