08 Patient Temperature
1 High
Medium Priority Alarm
The Patient Temperature 1 reading
is above 39.5°C (103.1°F), and
the water temperature is above
39.5°C (103.1°F), and the system is
continuing to warm the patient when
the system is in a patient control
mode (e.g. Control Patient, Cooling or
Rewarming).
1. Verify Patient Temperature Accuracy
Confirm patient temperature using a secondary site.
Confirm that the primary temperature probe is properly placed
and registering an accurate temperature.
2. Verify Patient / Water Temperature Control
Observe patient temperature
Is the patient temperature decreasing?
Observe water temperature.
Is the water temperature <39.5°C (103.1°F)?
Is the water temperature decreasing?
If the water and/or patient temperatures are beginning to
decrease, the system is working correctly. Continue to monitor
patient temperature.
3. Verify Water Temperature Limits
In Normothermia Settings or Hypothermia Settings , confirm
that the water temperature low limit is set ≤10°C (50°F).
If necessary, set water temperature low limit ≤10°C (50°F).
Resume therapy.
Monitor water temperature and patient temperature.
If the water and/or patient temperatures are beginning to
decrease, the system is working correctly. Continue to monitor
patient temperature.
4. Verify Water Cooling – External Factors
Check environmental conditions that may affect cooling.
• Are the machine vents blocked?
• Is the room temperature too high?
• Is the oxygen heated?
• Are there hot lights or heating blankets on the
patient?
Remove any impediments.
Monitor water temperature and patient temperature.
If the water and/or patient temperatures are beginning to
decrease, the system is working correctly. Continue to monitor
patient temperature.
5. Verify Water Control – System Performance
Place unit in Manual mode, with water temperature set
<38°C (100.4°F).
Monitor water temperature and patient temperature.
If the water temperature is not decreasing to the commanded
temperature, the water cooling system is not working. Call BD
Customer Support.
If the water temperature decreases to the commanded
temperature, the water cooling system is working.
6. Verify Patient Control – System Performance
Place system back into the patient control mode.
Monitor water temperature and patient temperature.
If the water and/or patient temperatures are continuing to
decrease, the system is working correctly. Continue to monitor
patient temperature.
If the water temperature and/or patient temperatures are not
decreasing, call BD Customer Support.
09 Patient Temperature
1 Above High Patient
Low Priority Alarm
In Normothermia Therapy: The
Patient Temperature 1 reading is
above the High Patient Alarm setting
in Normothermia Settings.
In Hypothermia Therapy: The Patient
Temperature 1 reading is above
the High Patient Alarm setting in
Hypothermia Settings.
If desired, adjust the High Patient Alarm setting in Normothermia Settings or
Hypothermia Settings.
