EEG Safety Information
EEG Configuration and Monitor Upgrades The A.2 monitor release (software revision A.20.xx)
introduced a new feature that lets you rename EEG montages. It is not possible to clone EEG settings
between montages with different names, therefore all EEG settings are reset to factory defaults during
any upgrade/downgrade/cloning actions that mix releases/software revisions/configurations before A.2/
A.20.xx with subsequent versions. You must check that all EEG settings are correct before resuming
monitoring with a monitor that has been upgraded or cloned.
WARNING Do not touch the patient, or table, or instruments during defibrillation.
When connecting electrodes and/or patient cables, ensure that the EEG leads and connectors do not
come into contact with other conductive parts or earth.
High-frequency Surgery To reduce the hazard of burns in the high-frequency surgical neutral
electrode connection, the EEG electrodes should not be located between the surgical site and the
electro-surgical unit return electrode.
EEG and Electrical Interference
CAUTION Interference from a non-grounded instrument near the patient and electrosurgery interference can
cause problems with the waveform and the CSA.
Radiated field strengths above 1 V/m and patient signals 50 µV may cause noise on the EEG waves
at various frequencies. Therefore, it is recommended to avoid the use of electrical radiating equipment
in close proximity to the patient monitor. The noise does not influence the measurement accuracy.
Interference from ECG can be eliminated by adjusting the low filter settings.
