VIII. TROUBLESHOOTING
WATER
Water Not Cooling
•
Confirm the patient is cooling properly. If not, see VIII.
Troubleshooting–Patient Temperature–Patient Not
Controlling
for instructions.
•
Confirm the water temperature is not limited by a user
setting. See
VI. Operation Guide—Therapy Settings–
Water–High Water Limit or Low Water Limit for
instructions on adjusting the water temperature setting.
•
Confirm the water flow rate is adequate. Low flow will limit
the system’s ability to cool. If water flow is low, see
VIII.
Troubleshooting–Water–Low Water Flow for
instructions.
•
Confirm the air filter is not occluded with dust. If dust is
present, wipe surface with clean cloth. See section I
X.
Cleaning and X. Maintenance and Service for
instructions.
•
Operate the system in Manual Control mode with the
water temperature target set at 6˚C (43˚F). Confirm that
the water temperature approaches the target over a period
of 10 minutes. If so, the system is operating properly. If
not, contact BD Customer Support.
Water Not Warming
•
Confirm the patient is warming properly. If not, see VIII.
Troubleshooting–Patient Temperature–Patient Not
Controlling
for instructions.
•
Confirm the water temperature is not limited by a user
setting. See
VI. Operation Guide—Therapy Settings–
High Water Limit or Low Water Limit for instructions on
adjusting the water temperature setting.
•
Confirm the water flow rate is adequate. Low flow will limit
the system’s ability to warm. If water flow is low, see

instructions.
•
Confirm the air filter is not occluded with dust. If dust is
present, wipe surface with clean cloth. See section I
X.
Cleaning and X. Maintenance and Service for
instructions.
•
Operate the system in Manual Control mode with the
water temperature set at 40˚C (104˚F). Confirm that the
water temperature rises above room temperature over a
period of 10 minutes. If so, system is performing properly.
If not, contact BD Customer Support.
Extended Cold Water Exposure
Exposure of the skin to low or high water temperatures for an
extended period of time may increase the risk for skin injury.
The clinician should monitor the patient and water
temperatures displayed on the Arctic Sun™ Temperature
Management System therapy graph to properly assess the
progress of the temperature management therapy.
Additionally, the Arctic Sun™ Temperature Management
System incorporates an extended cold water exposure alarm.
If the water temperature remains below 10°C (50°F) for 8 of the
previous 10 hours, the device will issue a low priority alarm.
The alarm will recur every 1 hour if the condition continues.
After the device has issued 11 extended cold water exposure
alarms, it will issue a prolonged cold water exposure
If a patient has been cooled continuously for over 4 hours and
has NOT reached target temperature, the water temperature
has been below 10°C (50°F) for greater than 8 continuous
hours, or extended cold water exposure alarm has been issued
it is important to assess the patient’s skin underneath the
ArcticGel™ pads and consider and address the potential
causes following the steps outlined below.
•
Verify the custom parameters.
◦
Patient target is set to the correct temperature.
See
VI. Operation Guide–Therapy Settings on
setting patient target temperature.
◦ One of the automatic patient control modes (e.g.
Control Patient, Cooling or Rewarming) is activated.
(The system is not in Manual Control mode.)
◦ The high water temperature limit and low water
temperature limits are set correctly. See
VI.
Operation Guide–Therapy Settings .
•
Verify Pad Sizing and Coverage
◦
A full set of four ArcticGel™ pads of the appropriate
size for the patient applied to the patient.
◦ For patients > 100 kg (220 lbs), 1 or 2 Universal pads
are added as required for adequate coverage.
•
Verify System Performance
◦
Water flow rate should be greater than the minimum
flow rate requirements specified in the ArcticGel™
pads IFU at least 1 hour continuous use.
See
VIII. Troubleshooting–Water–Low Water Flow
for troubleshooting instructions.
◦ Water temperature is responding appropriately to
control patient temperature towards the target.
If not see
VIII. Troubleshooting–Water–Water Not
Warming .
•
Verify Shivering Control
◦
If the device settings, pad sizing and system
performance is correct and patient target temperature
is still not reached and/or water temperature remains
below 10˚C (50˚F), then the patient is generating
excessive heat, most likely from shivering which may
or may not be visible.
◦ Consider administration of additional medication for
shivering control, adequate for the patient weight and
magnitude of shivering.
◦ Evaluate patient response to medication.
