Processed EEG Variables 

 

Variable Name 

Description 

Range 

Bispectral Index 
(BIS) 

The output from a multivariate discriminate 
analysis that quantifies the overall bispectral 
properties (frequency, power, and phase) 
throughout the entire frequency range. 

0 – 100 

Signal Quality 
Indicator (SQI) 

A measure of the signal quality for the EEG 
channel source(s) that is calculated based on 
impedance data, artifact, and other variables. 
Not affected by Suppression Ratio. 

0 – 100 

20 points per bar 

EMG 

The absolute power in the 70-110 Hz range. The 
power value is reported in dB with respect to 
0.0001

μ

V

2

. All the artifact detection is turned 

off for this variable. 

30 – 80 dB Trend 

30 – 55 dB Bar  

Graph 

Suppression Ratio 
(SR) 

The percentage of epochs in the past 63 seconds 
in which the EEG signal is considered 
suppressed. 
 

0 – 100 %
