Overview
This chapter explains how to start treatment and change target temperature and
rate settings during treatment. It provides instructions on the proper way to end
treatment, including how to download patient temperature trend data to a laptop
computer and how to remove used components and dispose of them safely.
Subsections at the end of this chapter provide detailed procedures for recovering
from improper shutdowns, including special procedures for downloading patient
temperature trend data.
In this Overview section, we will present the main features of system as they are
presented to the user on the display of the system. This section will help you be
familiar with the features of the System before starting to use it.
After the Overview, you will find sections that describe in detail the operation of
the System - see Operating the System. The sequence of events that you must
pass through in starting the System varies with the way it was last turned off.
Within this section we will review the different patterns of interaction you will
experience. Specifically we will review:
 Your first case with the System.
 Variations in the SETUP sequence of the System
 Ending
procedures.
Operating States in the System
The System has three operating states: SETUP, STANDBY and RUN.
SETUP
When the System is first powered up, it goes through a sequence of self tests. It
tests its own electronics and internal sensors. These tests are called the POST
(Power On Self Test). It is normal to hear two beeps during POST. Then the
System tests its thermometer functions and its cooling engine. The extent of the
testing during SETUP and the interactions required of you by the system both
vary depending upon the state of the system when it was last turned off.
You can pre-set the bath temperature so that the system is either coolingor
warming the bath in SETUP.
Patient temperature alarms are not active in SETUP.
System Self Tests
The System performs self tests both at initial power-on and then hourly during
operation. These tests allow the system to check its own performance.
Thermometer Functions Self Test
The Primary Patient Temperature monitoring circuit (T1) is checked during
SETUP and then hourly against the System internal high resolution calibration
resistor. This is a quick test.
