From STANDBY you may toggle into and out of RUN. You may only return to
SETUP by powering down the system.
RUN - Treatment Modes
Once you are ready to begin treatment, you may move from STANDBY to RUN.
The System will become fully operational provided that all its sensors indicate
that it is ready. Alerts will trigger if it is not.
There are three treatment modes in RUN: “Max Power”, “Controlled Rate” and
“FEVER”.
Max Power (MAX)
In this treatment option, the System seeks to make the patient’s temperature the
same as the selected target temperature. It will keep the peristaltic pump
operating unless the patient’s temperature “inverts”. This occurs whenever:
A. Bath Temperature > Patient Temperature > Target Temperature,
OR
B. Bath Temperature < Patient Temperature < Target Temperature.
Controlled Rate
In this treatment option, the System will attempt to move the patient’s
temperature to the target temperature at the programmed rate of heat exchange
(°C /hr). When the patient reaches the target temperature, the System will revert
to the MAX treatment option i.e. it will attempt to make the patient’s temperature
the same as the selected target temperature.
NOTE: Controlled Rate
Controlled rate operates in both warming and cooling modes.
FEVER (FVR)
In this treatment option, the System will start cooling the patient once the patient
temperature is above the target temperature. It does this by keeping the bath at
its coldest permissible temperature and then operating the peristaltic pump
whenever the patient’s temperature moves above the target temperature.
WARNING! “Lo” patient temperature alarm limit with “FEVER”
The System will NOT heat the patient when the “FEVER” treatment option has
been selected. The “Lo” patient temperature alarm limit ensures that an alarm
occurs should the patient stop regulating his/her own body temperature. Such
patients will cool to room temperature. This can occur when the patient dies
or becomes comatose.
INVESTIGATE ALL PATIENT TEMPERATURE ALARMS.
