Alarm Problem Solution
51 Patient Temperature
1 Below Control Range
Low Priority Alarm
Patient Temperature 1 is less than
31°C (87.8°F) while in a patient
control mode (e.g. Control Patient,
Cooling, or Rewarming).
1. Verify patient temperature from a secondary site. If patient temperature
is less than 31°C (87.8°F), use Manual Control to raise patient temperature
above 32°C (89.6°F) then resume using the previous control mode.
2. Check that the Temp In 1 probe is properly placed in the patient and has
not dislodged.
3. Check that the Temp In 1 probe is connected to the Temp In 1 cable /
connector on the back of the Control Module.
4. Check that the connection between the temperature probe and
temperature cable is secure.
5. Check that the connection between the temperature cable and the Temp
In 1 connector is secure.
6. Check the integrity of the temperature cable. Flex the cable to check for an
intermittent fault. If damaged, replace cable.
7. Replace the patient temperature probe.
52 Extended Period of
Cold Water
Low Priority Alarm
The circulating water temperature has
been below 10°C (50°F) for 8 of the
previous 10 hours.
The alarm will recur after 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 alarm.
Extended periods of cold water
delivery may increase the risk for skin
injury. Assess patient’s skin
underneath the ArcticGel™ pads.
1. Verify the custom parameters.
Patient target is set to the correct temperature.
See VI. Operation Guide–Therapy Screen–Control Patient
Settings for instructions on setting patient target temperature.
One of the automatic patient control modes (e.g. Control Patient
or Cooling) 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–High Water Limit or Low Water Limit .
2. 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.
The pads are well-adhered to the patient.
3. 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.
The patient temperature probe is properly placed and providing
an accurate and stable temperature.
4. 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: follow physician orders, institutional TTM protocol and
current medical guidelines.
Evaluate patient response to medication.
5. 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–Low Water Limit .
Set the patient target temperature to the lowest patient
temperature achieved. See VI. Operation Guide–Therapy
Screen–Hypothermia Therapy–Cooling or Normothermia
Therapy–Control Patient for instructions on setting patient
target temperature.
Discontinue cooling therapy.
