Nerve Integrity Monitor
Electrode Check panel pass/fail
The system measures impedance values of the electrodes to the patient to conrm the integrity of the connection. The electrode
check only indicates that the electrodes are making contact with the patient’s tissue. The system does not conrm that the needle is
inserted into the correct muscle. The user is responsible for ensuring the electrodes are placed, or inserted into the target muscles.
The above graphic illustrates that all channels have passed the electrode check. A red bar with a white X will replace the green bar
with a white checkmark if a channel(s) fails.
Electrode Check Show Details button
Press the Show Details button to see the actual impedance values. Refer to the “Troubleshooting” topic for more information.
Note: When you select , the system displays the normal electrode impedance limits if the number of channels is less than six.
Measure
When activated, press to enable and adjust the measurement cursor.
1. Enable the Measurement cursor on the main screen.
2. Select the cursor type. This determines where the cursor is initially displayed.
3. Adjust the cursor position.
Freeze
When activated, press to freeze the current waveform on the screen. The main screen shows “Display is Frozen” during this
time. Press again to end the freeze. Monitoring continues in the background when enabled and monitoring sounds still play.
Adjust view
Press to adjust the scale (Y-axis μV [amplitude] and x-axis mS [milli-seconds]).
