Patent ID: 8219187

Claim:
A method for providing an indication suitable for assessing a physiological condition of a patient, said method comprising the steps of: (a) obtaining two biosignals from the patient, each biosignal being obtained from a different location on the patient, the biosignals each containing an EEG signal component and an EMG signal component; (b) dividing each of the two obtained biosignals into the EEG signal component and the EMG signal component in a microprocessor; (c) carrying out an analysis of both the EEG signal component and the EMG signal component of the two biosignals in the microprocessor to obtain a complexity value for both the EEG signal component and the EMG signal component of the two biosignals; (d) selecting, on the basis of the complexity values, the lower complexity value of the EEG signal components for use as an indication of the EEG signal component and selecting the higher complexity value of the EMG signal components for use as an indication of the EMG signal component; and (e) utilizing the selected complexity values in the microprocessor to provide a physiological condition assessment indication of the patient.
