Monitoring EEG
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:
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 (SEF): The SEF is the frequency below which a defined percentage of the
Total Power lies. The percentage is set in Configuration Mode.
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.
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:
–
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).
