Using the NerveTrend feature
1. Identify a proximal location on the nerve at risk.
2. Stimulate the nerve at the proximal location using the supramaximal stimulus value.
3. Initiate a NerveTrend baseline. Refer to the “Probe-based functions” and “NerveTrend” topics for additional information.
4. After a successful baseline acquisition, stimulate the same anatomical location at the same stimulus intensity and document the
EMG response on the graph using the incrementing probe buttons or the Trend button on the NIM Vital system.
Note: the user can repeat this step multiple times throughout the procedure to visualize a change in the nerve function.
