Notify the physician if the patient’s temperature is not responding properly
or does not reach the temperature prescribed in the prescribed time or if
there is a change in the prescribed temperature range. Failure to inform
the physician of the deviation may result in injury to the patient.
Do not use the Blanketrol II system in the presence of flammables.
Risk of explosion can result.

Do not use alcohol. Alcohol may cause blanket deterioration.
Do not operate without water to avoid damage to internal components.
Do not overfill. Overfilling may result in overflow when the water in the
blanket drains back into the system when the system is turned off.

WARNING
A physician’s order is required for setting blanket temperature and use of
equipment. At least every 20 minutes, or as directed by physician, check
patient’s temperature and skin condition of areas in contact with blanket;
also, check blanket water temperature. Pediatric, temperature-sensitive,
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.
Do not place additional heat sources between the patient and blanket.
Skin damage may result.
Notify the physician promptly of any change in
The area between the patient and the blanket should be kept dry to avoid
injury to patient.
Use only YSI
400
series, or equivalent, probes on CSZ equipment. Failure
to do this will cause incorrect temperature readings.

GENERAL DESCRIPTION OF THIS MANUAL
This manual describes the operation, maintenance, and service of the CSZ
BLANKETROL II hyper-hypothermia system. Section One describes the physical and
functional characteristics of the BLANKETROL II System. Section Two describes how
to prepare the BLANKETROL II unit for general use. Section Three describes how to
operate the unit in the Manual Control Mode, Automatic Control Mode, and Monitor
Only Mode.
This manual is prepared for professional personnel who use the equipment for patient
care. It is designed to be stored with the BLANKETROL II unit and to be readily
available for reference when operating the BLANKETROL II System.

GENERAL DESCRIPTION OF THE BLANKETROL II SYSTEM
The CSZ BLANKETROL II, Model 222R Hyper-Hypothermia System is used to either
lower or to raise a patient’s temperature and/or maintain a desired patient temperature
through conductive heat transfer.
The CSZ BLANKETROL II unit is composed of a
heater, a compressor, a circulating pump, and a microprocessor board. This unit
requires no field adiustments or calibrations in order to maintain the precise
measurement of temperature and temperature safetv limits.

OPERATION
l4ANUAL
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.

The water flow indicator is a paddle-wheel in the

system, it must pass over the paddle-wheel causing it to spin (like a
pinwheel). The water flow indicator provides a visual display of the
general rate at which the water is circulating. For example, if the unit is
circulating water but the connecting hose is pinched, the circulation of
the water is restricted. The change in water flow decreases the speed
of the paddle-wheel.
When the problem of the pinched connecting hose is solved, an increase
in water flow can be seen by watching the water flow indicator increase
in speed. A total obstruction of the water path will cause the
wheel to stop completely.

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.
