The system regenerates the report with the updated case information.
Generate the report
Once the user is satised with the report content, the user can make a nal review of the report using the live preview window. The
tabs at the top of the window enable the user to jump to bookmarks for each section within the report, or use the expand button to

• Print button - sends the report to the attached printer.
• Save button - sends the report to the attached USB mass storage device and saves the formatted report as a .pdf format
on the USB drive. The system formats the lenames with the report type, year, month, day and time. For example,
Report_20190528_112530.pdf.
Reports are located in a case folder titled with date, sequential case, and procedure type.
Nervassure overview
The following topics contain information about how a Nervassure procedure is conducted.
Automatic periodic stimulation (Nervassure) is a process wherein a nerve at risk is continuously stimulated. The resulting EMG is
monitored and charted continuously in real time. You can plot and observe trends.
The plotted characteristics are:
• EMG amplitude (peak-to-peak, response to stimulation)
• Latency (time from stimulation to the “Onset” or peak of the EMG response), if enabled.
Every point plotted in the bottom half of the trend chart for each channel is a single EMG amplitude response. Each point plotted in
the top half of the trend chart for each channel is a latency response.
If a measurement falls outside of the threshold values, the points change color and the console issues an audible alarm to alert you
depending on what alarm settings you selected on the Advanced Settings panel.
Nervassure case set up
1. Select a user prole that has Nervassure procedures, or a default Nervassure procedure.
2. The Check Electrode screen displays two stim return electrodes that need to be connected. A green bar mark will appear in stim
return 2, when connected.
3. Press to proceed to monitoring.
