Breath pacing system and method for pacing the respiratory activity of a subject

摘要

To provide a breath pacing system and a corresponding method for pacing the respiratory activity of a subject that provide the possibility to adapt the output signal to the respiration characteristics of the subject automatically and effectively a breath pacing system (10) for pacing the respiratory activity of a subject and a respective method is proposed, comprising: an input unit (14) for generating or determining an input signal related to a respiration characteristic of a subject, a signal analyzing unit (16) provided to recognize a signal pattern within the input signal, and an output unit (12) for outputting output signals corresponding to a desired breathing sequence, wherein said output unit (12) is provided to be activated, upon a starting signal, to output a sequence of output signals comprising a signal pattern related to a previously recognized signal pattern.

主权项

1. A breath pacing system for pacing a respiratory activity of a subject, comprising:
an input unit generating an input signal related to a respiration characteristic of the subject, the respiration characteristic comprising at least one of an inhale phase and an exhale phase, a signal analyzing unit recognizing a signal pattern within the input signal, and an output unit outputting output signals corresponding to a desired breathing sequence, wherein said output unit, upon receiving a starting signal, outputs a sequence of output signals having a beginning and comprising a signal pattern related to a previously recognized signal pattern, and said sequence of output signals begins with an expand time of the output unit corresponding to the present inhale time of the subject or a contract time of the output unit corresponding to the present exhale time of the subject, said sequence of output signals transitions to a slow down phase independent of the input signal, wherein in the slow down phase, a frequency of the output signals in the sequence is decreased and an amplitude of the output signals in the sequence is increased in the slow down phase until the desired breathing sequence is reached.
