CareFusion Nicolet EEG Wireless Amplifier
CareFusion · Model Nicolet EEG Wireless Amplifier
• The Nicolet Wireless Amplifier features 24 referential, 4 differential, 4 DC and built-in Oximetry channel, enabling use for a variety of video EEG and LTM studies in ambulatory or clinical settings. • Connecting to an acquisition computer through a standard high–speed USB 2.0 cable eliminates the need for expensive proprietary cables and allows uploading of 24 hours of data from the amplifier to the station in less than 5 minutes (depending on sampling rates). • The NicoletOne multimodality software brings you a dynamic user interface that supports lab efficiency and productivity in a single system or an enterprise network with satellite locations. • The NicVue 3.0 SQL data management system coupled with our HL7 interface options and VLink support system provide pioneering resolutions to assist you in providing quality patient care.
Key tips
- ·Electrode impedance drives data quality more than almost any other single factor - check it before assuming an amplifier fault.
- ·Pre-case verification of intraoperative monitoring equipment isn't optional - a mid-case failure has direct surgical-decision consequences.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Electrode impedance high
MediumSymptoms: Noisy / flat channels, impedance alarm.
Root cause: Dry gel, poor contact.
Amplifier channel fault
MediumSymptoms: Dead channel, artifact.
Root cause: Front-end amplifier failure.
Stimulator output fault
MediumSymptoms: No stimulus delivered.
Root cause: Stimulator circuit wear.
Grounding / isolation issue
LowSymptoms: 50/60 Hz interference.
Root cause: Shield/ground break.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Electrode / lead impedance check
- ·Amplifier calibration
- ·Annual electrical safety test
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Electrode impedance high
- Confirm the presentation - typically noisy / flat channels, impedance alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: dry gel, poor contact.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the eEG electrode cap / cup per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
