Nerve Integrity Monitor
Troubleshooting
Should you encounter any diculty eliciting simulated responses from the NIM Vital system patient simulator, check the following:
• Verify that the Stimulus Measured is approximately the same as the Stimulus Intensity.
• Make sure the jumper cables are connected correctly between the SIMULATOR and PATIENT INTERFACE.
• Adjust the EVENT THRESHOLD setting on the NIM Vital system.
• Adjust the STIMULUS intensity on the NIM Vital system for adequate output.
• Clean the stimulator contacts of debris.
• Check the integrity of the stimulator or stimulus-dissection instrument and its connecting cable.
• Check for a blown fuse in NIM Vital system patient interface and replace with a proper valued fuse (shown near fuse box).
• Check for proper closure of fuse holder in the NIM Vital system patient interface.
