Nerve Integrity Monitor

After conrming the electrodes are properly placed in the patient and connected to the patient interface box, perform an Electrode

Check on the NIM Vital system. This may determine if the electrodes need to be re-inserted for better electrical contact to help

optimize monitoring.

If you are using the wired patient interface box, lay the patient interface box cable out of busy trac patterns and secure it to the

oor as needed.

Stimulators

The NIM Vital system Stimulator output supports the use of both monopolar and bipolar stimulating probes with a range of 0-50

mA.

Monopolar Incrementing probe

The single use incrementing probe provides the surgeon with the means to adjust the stimulation current and print or save the

monitoring screen shots from the sterile eld as well as other features.

The patient interface supports one incrementing probe. The smaller plug is color-coded black and plugs into the black (-) jack on the

patient interface box. The larger plug is also color-coded black and plugs into the large black (STIM CONTROL) jack on the patient

interface box. If you are using the incrementing probe adapter, plug the incrementing probe into the adapter and then plug the

adapter into the patient interface box. The monopolar stimulating probe delivers current to the patient and acts as the cathode. The

red electrode with white wire (+) is required for monopolar stimulation. It is referred to as the stimulus return or anode. Plug the red

connector of the red electrode with white wire into the white jack with a red ring (+). Route the white (+) stimulus return wire away

from the channel electrode wires.

Note: The Incrementing probe connector (2) has three indentations in the connector sleeve and one-o center key that must be

aligned with the incrementing probe adapter (3) or the connector may be damaged. Align white arrow (1) on side of Incrementing

probe connector with the black arrow on incrementing probe adapter.
