Abstract
The present invention provides a medical signal monitoring system and method for displaying physiological signals of different types and modalities in different formats on a single system. Physiological signals, e.g., electrical physiological signals from electrodes attached to a subject, are provided to the system. The raw wide band physiological signals may be recorded on disk, and may be processed multiple times to display desired signals of interest. The parameters used to process the signals to be displayed are selectable by an operator employing a user interface. The user interface allows an operator to define a set of panels in which one or more signals will be displayed. The type of panel selected to display the signal determines the basic format of the signal to be displayed, e.g., various types of waveforms. A signal to be displayed in a panel is defined by selecting, for example, the signals from two electrodes attached to a subject from which a montaged pair signal to be displayed is derived. The modality of the signal to be displayed, e.g., EEG, EMG, or evoked potential (EP) is operator selectable employing the user interface. The user interface also provides for operator selection of other display and analysis parameters, such as triggering, averaging, and spectral trend analysis. A signal to be displayed in a panel may be triggered from an auditory, visual, or electrical stimulation signal provided to a subject. The characteristics of the stimulation to be provided to the subject are operator selectable employing the user interface. A separate stimulus context may be established for each panel defined by an operator. Switching between different stimulus contexts is achieved via the user interface by activating a panel to which a stimulator context has been assigned.
