Patient Temperature; System Activity; Cursor; Status Bar - ZOLL IVTM Operation Manual

Patient Temperature

The patient temperature graph (labeled "Patient Temp") is scaled for any temperature between 31ºC and
41ºC (87.8ºF– 105.8ºF). The time scale can be set to any of four intervals (refer to Setting the Time Scale on
page 72 for details). Figure 4.66 shows the vertical temperature displayed in degrees Celsius, and the horizon-
tal time scale displayed for a 4-hour interval.

System Activity

The System activity graph (labeled "System") is scaled for any console activity, from maximum cooling to max-
imum warming. The horizontal time scale is the same as that set for the Patient Temperature graph. The verti-
cal scale uses a colored activity indicator:
• The red zone indicates coolant temperatures between 36ºC and 42ºC.
• The neutral point (between red and blue) indicates coolant temperature of 36ºC and also indicates when
the pump is not operating.
• The blue zone indicates coolant temperatures between 0ºC and 36ºC.

Cursor

The cursor is a fixed vertical line that runs through the center of both graphs. When the temperature trend
graph is displayed, you may turn the Press for Menu/Enter knob to scroll the display screen to the left or right.
As data scrolls under the cursor, the top of the display screen shows the time and date of the data under the
cursor.
Turn the knob clockwise to scroll to the right. As you scroll to the right, the time and date display will indicate
later data. By scrolling right to the end, you can display the most current data.
Turn the knob counterclockwise to scroll to the left. As you scroll to the left, the time and date display will indi-
cate earlier data. By scrolling left to the end, you can display the data collected when treatment began.

Status Bar

Across the bottom of the display screen is a status bar which displays the patient's temperature, the status of
the console, and the target temperature for the data point under the cursor.
The patient's temperature and target temperature are displayed using the current temperature notation setting
(Celsius or Fahrenheit).
The status field uses colors to display one of nine status messages that are described in the following table.
