EEG and auditory evoked potentials
EEG measurement setup
EEG equipment to patient connection
1. Module with EEG, AEP and FEMG measurement capability
2. EEG headbox and cable, N-EEG
3. EEG leadset: preconfigured or your own montage. EEG electrodes (cup, needle,
or adhesive)
4. Earphones are required for AEP (auditory evoked potentials)
CAUTION
Do not cover the EEG headbox as it may overheat.
NOTE
When measuring both AEP and BIS or Entropy be aware of
possible interference issues. Familiarize yourself with all of
these measurements and their safety statements.
EEG module keys
There are two keys on the module:
EP Start/Stop Starts and stops auditory evoked potential measurement with
the defined settings.
Imp. Check Starts the manual measuring of the electrode impedance.
The same keys can be found on the headbox.
EEG electrode sites
●
Follow the electrode manufacturer’s instructions for the frequency of changing
the electrodes.
●
Only use electrodes that are intended for EEG measurement.
●
Use one type of electrodes in the whole montage.
