26.1 EEG Introduction
The Electroencephalograph (EEG) module measures the spontaneous , rhythmic electrical activity of the cortex.
Continuous EEG is routinely used in critical care and during anesthesia applications.
The EEG module can continuously monitor EEG signal from up to four channels. It can also display Density
Spectral Arrays (DSA) and Compressed Spectral Arrays (CSA).
EEG monitoring is intended for adult, pediatric, and neonatal patients.
26.2 EEG Safety Information
:
• The conductive parts of electrodes and connectors should not contact other conductive parts,
including earth.
• To reduce the hazard of burns in the high-frequency surgical neutral electrode connection, the EEG
sensor should not be located between the surgical site and the electrosurgical unit return electrode.
• The EEG electrode must not be located between defibrillator pads when a defibrillator is used on a
patient under monitoring.
• To ensure proper defibrillator protection, use only recommended cables and leadwires.
• EEG is a complex monitoring technology intended for use only as an adjunct to clinical judgement
and training.
• Only use parts and accessories specified in this manual. Follow the instructions for use and adhere to
all warnings and cautions.
• Implanted devices (for example cardiac pacemakers), other patient connected equipment, and other
equipment near the patient (for example high-frequency surgical units) can cause interference on
the waveform, numerics, and the CSA presentation.
• External radiating devices may disturb the measurement. It is recommended to avoid the use of
electrical radiating equipment in close proximity to the monitor.
• Interference from ECG can be eliminated by adjusting the filter settings.
