Temperature Trend Graph
Temperature trend data can be displayed as an interactive graph on the screen.
The display is a time-series of patient temperature (from the primary temperature
probe) and System activity, plotted in two graphs. The patient temperature graph
plots temperature vertically and time horizontally. The System activity graph plots
cooling/warming activity vertically and uses the same time scale horizontally. An
example of the patient temperature trend display is shown below.
Figure 4-68. Temperature Trend Display.
Patient Temperature
The patient temperature graph (labeled “Patient Temp”) is scaled for any
temperature between 31º C and 41º C (87.8º– 105.8º F). The time scale can be
set to any of four intervals (refer to Setting the Time Scale, later in this chapter,
for details). Figure 4-68 shows the vertical temperature displayed in degrees
Celsius, and the horizontal time scale displayed for a 4-hour interval.
System Activity
The System activity graph (labeled “System”) is scaled for any System activity,
from maximum cooling to maximum warming. The horizontal time scale is the
same as that set for the Patient Temperature graph. The vertical scale uses a
colored activity indicator:
 The red zone indicates coolant temperatures between 36º C and 42º C.
 The neutral point (between red and blue) indicates coolant temperature of
36º C and also indicates when the pump is not operating.
 The blue zone indicates coolant temperatures between 0º C and 36º C.
