patients with vascular disease, and operating room patients should be
checked more frequently.

order to avoid serious injury or death.

The method of temperature control provided by all hyper-hypothermia
units presents the danger of heating or cooling body tissues, particularly

the skin, to a point where they are injured, i.e., burns or frostbite,

respectively. Depending on the extent and severity of a burn, very serious
and even fatal complications may arise.

Prevent excessive and/or prolonged tissue pressure and shearing forces,
especially over boney prominences, to prevent skin damage that may
result.

l-2. GENERAL DESCRIPTION OF THE BLANKETROL II SYSTEM

(cont’d)

Water is heated or cooled and pumped from the unit to a blanket. The blanket* rests
under and/or on top of the patient and is designed so that the water circulates through

the blanket and returns back to the unit.

If cooled water is circulated through the blanket, the desired effect is to reduce the
patient’s temperature. If warmed water is circulated through the blanket, the desired
effect is to elevate the patient’s temperature.

The BLANKETROL II unit can be set so that it operates based on the temperature of

the circulating water (Manual Control) or it can be set so that it operates based on the
temperature of the patient (Automatic Control).

* The recommended blanket(s) for use is described in Section (I-5.)

1-3. CLINICAL APPLICATIONS

The BLANKETROL II unit is used primarily in hospital Intensive and Coronary Care

Units, in Operating,
Medical/Surgical floors. This hyper-hypothermia system can be used with adult and

pediatric patients to produce normothermia by lowering a patient’s elevated
temperature or raising a patient’s sub-normal temperature. It can also be utilized to
maintain normal body temperature (normothermia) during surgical procedures.

Surgically, this system can be used to produce moderate to profound hypothermia for
such procedures as amputations, cardiopulmonary by-pass surgery, vascular surgery,
and intracranial surgery. Medically, this system can be used to decrease the rate of
circulation, to reduce intracranial pressure, to control cerebral edema, and to reduce
oxygen requirements. This system is also used in the treatment of burns, shock,
cardiac arrest, and gastrointestinal hemorrhage.

Operation of the BLANKETROL II unit requires the use of the blanket(s) designed to

circulate warm or cool distilled/sterile water, a connecting hose with quick-disconnect

male and female couplings, and a YSI 400 series thermistor probe (if Automatic
Control Mode is to be utilized). BLANKETROL II System Equipment and accessories
are listed in Figure 3-l.

CSZ offers the widest selection of hyper-hypothermia blankets to serve your needs
providing both reusable and single-patient use blankets. The reusable blanket, the
lightweight
disconnect, error proof male and female couplings. A single-patient use blanket,

MAXI-THERM@, and a reusable connecting hose are also available. All CSZ blankets
offer significantly higher thermal transfer capability than any other brand of
hypothermia blankets.

CSZ also offers a disposable blanket cover, the DISPOSA-COVER’“, that guards
against stains, helps prevent cross-contamination, enhances patient comfort, provides
a moisture barrier, saves on nursing time, and offers greater economy because it
prolongs blanket life and reduces laundry costs.

COOLING SYSTEM

The BLANKETROL II cooling system is composed of a compressor, a condenser, a

condenser fan, an evaporator coil, water temperature control, solenoid valve, hot gas

bypass valve, and three low temperature safety devices. Temperature ranges are
described in Section (1-6.4.).

The refrigerant of the cooling system flows through the evaporator coil located in the

circulating reservoir.

The water circulating in the reservoir flows over the evaporator

coil and is cooled.

The cooling system is operational in the Manual Control or Automatic Control Modes
whenever the control system calls for a decrease in the temperature of the circulating
water. It is important to note that the rate of change in the circulating water
temperature is not directly proportional to the rate of change in the temperature of the
patient.

CIRCULATING SYSTEM

The BLANKETROL II circulating water system is composed of a magnetically driven
circulating pump, a dual compartment reservoir, a water filter, quick-disconnect
fittings, connecting hose, and hyper-hypothermia blanket(s).

The 2 gallon (7

liters) capacity dual compartment reservoir is composed of the circu-
lating reservoir situated under and connected to the replenishing reservoir. When the
operator fills the reservoir with distilled/sterile water

gallons
(5.6 liters) are held in the replenishing reservoir. The water moves from the
replenishing reservoir to the circulating reservoir by gravity drain as needed.

The circulating water flows over and around the heating/cooling element located in
the circulating reservoir. The heated or cooled water then flows out of the reservoir
to the circulating pump, through the pump housing, through connecting hoses over
a water temperature sensor to the hyper-hypothermia blanket(s). The water circulates
through the blanket(s) and returns to the unit. The water then passes through the
water flow indicator, through the water filter and returns to the circulating reservoir
to be reheated or

retooled

and then recycled.

In addition, the circulating reservoir contains a low water level sensor which shuts

down the unit and sounds the alarm if the water level drops below a preset amount.
The unit becomes operational again after the water level is restored to normal.

SUGGESTIONS FOR PROTECTING THE RESERVOIR FROM
BACTERIA AND FOR DECONTAMINATION GUIDELINES

If distilled/sterile water is used and changed monthly, there should be no problem with
bacteria forming in the reservoir or blanket(s). If hospital procedures require the use
of a bacteriostatic or bactericidal agent, we suggest Hospital-Approved
Agents which are non-acidic and non-foaming.

Bacteriocidal

NOTE:

DO NOT USE DE-IONIZED WATER. THE MAJORITY OF
DE-IONIZERS DO NOT MAINTAIN A NEUTRAL PH OF 7. IF THE
DE-IONIZED WATER IS ACIDIC, IT WILL CAUSE A BATTERY

Check the level of distilled/sterile water in the reservoir. To do so, lift
the cover of the water fill opening and the water should be visible,
touching the strainer.

If needed, carefully add distilled/sterile water. In
addition, if the water falls below a preset level, the alarm sounds and the
Status display flashes LO WATER. The operator cannot proceed until
this is corrected as described in Section (3-8.).

Check that the power switch is in the OFF position.
