1. Cerebral Function Monitor
Group 14

2. Members JP Day, BME Brian Snelling, BME Colin Compas, BME
Dr. Paul King, Faculty Advisor
Dr. Bill Walsh, Advisor
Dr. John Wikswo, Collaborator

3. Device Description Olympic CFM 6000 Cerebral Functioning Monitor
Measures brain activity
3 leads
Normal reading
Between 5-10 mV
Abnormal readings
Downward shift in range
Encephalopathy
Seizures

4. Project Description Electromagnetic Interference ECG Neonatal Devices
Movement changes readings
Manual suggests moving devices
Based on output wattage
Some distances unrealistic
ECG
1000 greater in amplitude
Physically close to brain

5. Completed Work Met with Dr. Bill Walsh
Discussed problem in detail
Toured Neonatal wing of VUCH
Opportunity to evaluate the machine
Used infrequently
Access to room/machine
Began brainstorm of possible solutions
Move equipment
Shield device
Shield equipment

6. Completed Work Read CFM literature Olympic Manuals
Segregation Recommendations
Distances
Based on Wattage
Alternate SOP Manual
Examples of Interference
All types
Procedure Clarifications
