Symptom
The patient does not
cool. The activity
monitor indicates
" " and
MAX COOLING
the patient's temper-
ature is increasing.
The patient does not
cool. The activity
monitor does not
indicate "MAX
COOLING" and the
patient's temperature
is increasing after 45
minutes of sustained
activity.
The patient's temper-
ature is more than
0.5º C below the
setpoint.
The patient does not
stop cooling. The ac-
tivity monitor indi-
cates " "
MAX COOLING
when the target tem-
perature has been
reached.
The patient is
warming (when set
for cooling).
Probable Cause
The heat exchanger coil is
not in the coolant
reservoir.
The System is not
operating within specifi-
cations.
The System is not
operating within
specifications.
The patient's resistance to
hypothermia has dimin-
ished, resulting in a
temperature controller
undershoot.
Machine malfunction.
A cooling or temperature
controller fault has
occurred.
A cooling or temperature
controller fault has
occurred.
Corrective Action
Place the heat exchange coil in the
reservoir.
Verify operation by performing the cooling
engine power test described in the System
Service Manual.
Download the TempTrend data file. If the
coolant temperature is above the limits
below, perform the cooling engine power
test described in the System Service
Manual.

Fortius
Monitor the patient's temperature. If the
patient's temperature drops more than one
degree below the target temperature,
ensure that the System is operating normal-
ly. If the coolant temperature is at or below
the patient's temperature, the activity moni-
tor should indicate warming and the pump
should be off. Use warming blankets to
stabilize the patient's temperature.
See above for correct machine function. Use
conventional methods to rewarm the patient
and discontinue use of the System.
If the activity monitor indicates "
" and the patient's temperature is one
ING
degree below the target temperature, dis-
continue treatment and contact ZOLL.
If the target temperature is below the
patient's temperature, and the activity
monitor does not indicate cooling activity,
discontinue treatment and contact ZOLL.
