18.7 Changing the BIS Smoothing Rate
The smoothing rate defines how the monitor averages the BIS value. With the decline in

Contrarily, the monitor provides a smoother BIS trend with decreased variability and sensitivity
to artifacts.
To change the smoothing rate, open the
BIS Setup menu and set Smoothing Rate to 10 sec, 15
sec or 30 sec.
