53 Prolonged Cold Water

Exposure
Medium Priority Alarm

The circulating water temperature

has been below 10°C (50°F) for

a prolonged period of time. The

extended period of cold water alarm

has been issued 11 times. The alarm

was first issued after the system

sensed that the water temperature

was below 10°C (50°F) for 8 of 10

hours. The alarm was then issued

an additional 10 times every

1 hour because the situation was not

resolved.
Prolonged cold water exposure

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–Hypothermia

Therapy–Cooling

Normothermia Therapy – Control Patient

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

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

Normothermia

Therapy – Control Patient

for instructions on setting patient target

temperature.

Discontinue cooling therapy.
