Abstract

A device provides a first data signal that indicates an activity of at least one muscle of a patient that is relevant for an inspiratory breathing effort and a second data signal that indicates an activity of at least one muscle of the patient that is relevant for an expiratory breathing effort. The data signals are generated from electromyography (EMG) signals detected by surface electromyography sensors. A computer is configured to determine breathing phase information on the basis of a breathing signal and to check at least one of the electromyography signals or at least one of the separated signals for detectability of a heart signal component and further to assign the signals to an inspiratory breathing activity as well as to an expiratory breathing activity of the patient as a function of the breathing phase information.
