The user can also choose NONE for the secondary variable; in this case, no secondary
variable will be shown on the BIS™ trend graph, and no secondary variable scale will
be seen on the right Y axis of the graph. Reference Figure 48. Secondary Trend Selection
on page 126.
When a secondary variable is displayed on the BIS trend, the vertical Y axis scale for
the secondary variable is displayed on the right side of the graph, while the BIS scale
is displayed on the left side. The color of the secondary variable trend line on the
graph and its vertical Y axis scale will match, and will differ from the BIS trend graph
and scale color, to enhance clarity.
To select a secondary variable, open the secondary variable drop-down menu that
can be reached by the following methods:
Main Menu>Display Settings>select a trend display that includes the
BIS graph>Secondary drop-down menu>select your preferred secondary
variable>click APPLY.
BIS trend graph on home screen>EMG (or currently selected secondary
variable) drop-down menu>select your preferred secondary variable
Any change made with either of these methods will be reflected in all BIS trend
screens.
For an example of a secondary variable on the BIS graph, reference 3.9.1 BIS Trend
Graph on page 96.
