Monitoring EEG

18
The Electroencephalograph (EEG) module monitors the patient's cerebral function by measuring the
electrical activity of the brain. It provides the monitor with two channels of realtime EEG waves, EEG
trend information in the form of Compressed Spectral Arrays (CSA), and up to eight of the following
numerics:
Spectral Edge Frequency - The SEF is the frequency below which a defined percentage of the Total
Power lies. The percentage is set in Configuration Mode.
Mean Dominant Frequency (MDF) - The MDF is the mean value of the frequency which
dominates the measured EEG.
Peak Power Frequency (PPF) - The PPF is the frequency with the highest measured amplitude.
Total Power (TP) - The TP numeric indicates the power in the measured frequency band.
Percentage of total power in each frequency band:

EEG Monitoring Setup

Plug the trunk cable into the EEG module.
1
Prepare the patient's skin prior to placing the electrodes. Good electrode-to-skin contact is
2
important for a good EEG signal, as the skin is a poor conductor of electricity.
Select the desired electrode montage in the
3
window.
Attach the reference electrode first.
4
Place the electrodes on the patient's head according to the selected montage. Use electrode gel if
5
you are not using pre-gelled electrodes. Remember to select a site where the signal will not be
interfered with by muscle artifacts.
Connect the electrode connector end to the trunk cable.
6
Alpha
waves (8 to 13 Hz)
Beta
waves (13 to 30 Hz)
Theta
waves (4 to 8 Hz)
Delta
waves (0.5 to 4 Hz).
Shave hair from sites, if necessary.
Wash sites thoroughly with soap and water. We do not recommend using ether or pure
alcohol, because this dries the skin and increases the resistance.
Use a skin preparation paste to remove skin cells and oil before placing the electrodes.
