WATER (Continued)
•
Make Clinical Decision
◦
If all of the above considerations have been
addressed and the patient still has not reached target
temperature the physician and nursing staff make a
clinical decision to limit the cold water exposure:
◦ Increase low water temperature limit. See VI.
Operation Guide–Therapy Settings Hypothermia
Settings–Low Water Limit
or Normothermia
Settings–Low Water Limit.
◦ Set the patient target temperature to the lowest
patient temperature achieved. See
VI. Operation
Guide–Therapy Settings on setting patient target
temperature.
◦ Discontinue cooling therapy.
Extended Warm 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 warm water exposure alarm.
If the water temperature remains between 38°C (100.4°F) and
40°C (104°F) for an extended period of time, the device will
issue an alarm. The alarm will recur if the condition continues.
If an extended warm 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. Consider
reducing the maximum water temperature setting.
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.

Make Clinical Decision
◦
If all of the above considerations have been
addressed and the patient still has not reached target
temperature the physician and nursing staff make a
clinical decision to limit the warm water exposure:
◦ Decrease high water temperature limit. See VI.
Operation Guide–Therapy Settings Hypothermia
Settings–High Water Limit
or Normothermia
Settings–High Water Limit.
◦ Set the patient target temperature to the highest
patient temperature achieved. See
VI. Operation
Guide–Therapy Settings on setting patient target
temperature.
◦ Discontinue warming therapy.
Low Water Flow
•
Confirm that all of the pad connectors are fully seated in
the fluid delivery line manifolds.
If not fully seated, reseat connectors.
•
Check the pads for foam-to-foam folds or buckles created
during placement.
If folds or buckles, smooth out and reapply pads.
•
Check the pad lines for kinks or occlusions.
If kinks or occlusions, straighten lines to remove. BD
recommends use of fluid delivery line straps to keep lines
from kinking.
•
Check the pad connectors for a continuous stream of air
bubbles.
If air bubbles are observed, disconnect one pad at a time
and wait one minute. If flow increases during pad
disconnect, the pad is damaged. Replace the damaged
pad with a Universal pad.
PATIENT TEMPERATURE
Patient Not Controlling
A patient’s temperature may not always be controlled as
precisely as expected. This can lead to conditions where the
patient temperature overshoots the target temperature high or
low, the patient fails to cool, rewarms too quickly, or is unstable
at the target temperature. In each case the following steps can
be taken to improve the level of control:
•
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 to the standard kit as required for adequate
coverage.
◦ The pads are well-adhered to the patient.
•
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.
