Nerve Integrity Monitor
P5 Avoid accidental contact between ‘PATIENT APPLIED PARTS’ and other conductive parts including those connected to
protective earth.
P6 The NIM Vital is only compatible with the metal Muting Probe (Ref - 8220325). Earlier model Muting Probes are not
compatible.
P7 The muting detector is susceptible to damage from dropping. Visually inspect inner jaw surfaces for cracking, chipping or
damage prior to use. Insucient muting may result.
P8 The patient interface is susceptible to damage from dropping. Visually inspect for damage prior to use. Inability to monitor
may result.
P9 The Ethernet connection of the NIM Vital Console, if activated, is intended to be connected to the hospital network. Do not
connect it to other equipment.
P10 At the end of their life cycle, all NIM Vital System electronic components must be sent to a WEEE recycling center or disposed
of according to local regulations.
P11 The NIM Vital console contains a Li-Ion battery pack that the user installs/replaces. Failure to follow the instructions for proper
installation/replacement of the Li-Ion battery pack may could result in a hazard.
P12 The Patient Interface contains a Li-Ion battery pack that must be replaced by trained service personnel only. The replacement
of Li-Ion batteries by inadequately trained personnel could result in a hazard.
P13 The multiple socket outlet (MSO) inside the locked drawer of the NIM Vital Cart is only intended to power the NIM Vital
Console and NIM Vital Power Isolator for Printer. Connecting both NIM Vital Console and NIM Vital Power Isolator for Printer
into the MSO eectively leads to create a Medical Electrical system. The system has been tested and met the applicable
portions of the IEC 60601-1 standard.
a. Do not plug any device into the MSO other than the NIM Vital Console and NIM Vital Power Isolator for Printer.
b. Do not overload the MSO by using it for multiple systems. The MSO shall be only used for supplying power to one NIM Vital
Console and one NIM Vital Power Isolator for Printer.
c. Printer shall be always powered through the NIM Vital Power Isolator for Printer.
d. Do not plug the power cord of the NIM Vital Cart into an extension cord or an additional MSO.
P14 The battery inside the NIM Vital Console can only power the system for a short period of time. NIM Vital system shall be always
connected to mains power for extended use and loss of power source would result in risk of loss of monitoring.
P15 To avoid the risk of electric shock, this equipment must only be connected to a supply main with protective earth.
P16 A baseline EMG response should be obtained with a stimulating probe once the nerve(s) of interest are identied. Nerve
integrity should be checked with a stimulating probe then compared to the baseline throughout the procedure.
NIM quick monitoring set-up
The following procedure for OR sta users is not meant to replace a complete understanding of this user’s guide but may serve as
a quick reminder of basic NIM setup, monitoring screens, and monitoring sounds. Refer to the ‘“MONITORING tab” topic for more
information.
1. Place the NIM Vital system within the surgeon’s view and plug the NIM power cord into the dedicated outlet.
2. Press on the bottom right of the console screen.
3. The system automatically runs the self-test until you hear the bleedle tone.
4. On the NIM Vital Setup screen, select the default prole followed by a surgical specialty and specic procedure to be monitored.
5. After selecting a procedure, the Connect Devices screen appears on the NIM Vital Setup screen. Undock the patient interface
from the console base. Wait for the solid blue paired wireless symbol to appear on the patient interface box which indicates a
wireless connection.
Note: If the wireless is not available, plug in the PI cord between the console and the PI. The console connector is located on the
back-left side and is marked by a PI box symbol (refer to the “Buttons and indicators” and “Symbols” topics for more information).
Anesthesia Note: Do not use long-term paralyzing anesthetics to ensure proper EMG monitoring.
6. After the patient interface connects to the NIM Vital system, press to progress to the Check Electrode screen. The Electrode
placement guide appears indicating how to connect the system.
7. Ensure the date and time are synchronized with the OR clock. Optional: Enter case information using the Edit Case information
button located on the top right of the screen.
8. Following the illustration on the screen, connect all color-coded cables (subdermal electrodes or EMG tube, ground, and STIM 1
return [red with white wire]) to the corresponding patient interface.
Note: The automatic electrode check shows one of the following for each connection: green bars with white checkmarks conrm
the integrity of the connections. Red bars with white Xs indicate a bad connection. White, spinning icons indicate the system is
checking the connection.
