EEG Monitoring Setup
1
Plug the trunk cable into the EEG module in the Flexible Module Server.
2
Prepare the patient’s skin prior to placing the electrodes. Good electrode-to-skin contact is
important for a good EEG signal, as the skin is a poor conductor of electricity.

– Shave hair from sites, if necessary.
– Wash sites thoroughly with soap and water. We do not recommend using ether or pure alcohol,
– 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.
3
Select the desired electrode montage in the
Setup EEG
menu or in the
EEG Impedance/
Montage
window.
4
Attach the reference electrode first.
5
Place the electrodes on the patient’s head according to the selected montage. Use electrode gel if
you are not using pre-gelled electrodes. Remember to select a site where the signal will not be
interfered with by muscle artifacts.

interfered with by muscle artifacts.
6
Connect the electrode connector end to the trunk cable.
7
Check the electrode-to-skin impedance in the
EEG Impedance/Montage
window.
8
For good signal quality, keep all lead wires together and away from other electric devices and
metallic bodies.
