Figure 38. SQI Indicator
A high SQI will be indicated by five complete green bars, as seen in the figure above.
Lower values will be indicated by fewer green bars, two orange bars (denoting
excessive artifacts in the EEG signal), or one red bar only (denoting a very low SQI
value).
If measuring with a 4-channel system, the SQI display will appear for each
hemisphere.
3.10.4. Burst Count
Burst count is displayed with two indicators: as a numerical value, and as a trend, if
selected as a secondary trend on the BIS graph.
Burst count is activated by connection of an Extend Sensor or Bilateral Sensor. Thus,
the burst count will appear as a numeric and become available as an option for a
secondary trend on the BIS graph only when an Extend or Bilateral sensor is used.
If measuring with a 4-channel system, the Burst Count display will appear for each
hemisphere.
