OPERATION/TECHNICAL MANUAL
Cincinnati Sub-Zero Products, Inc., reserves the right to make equipment changes and
improvements, which may not be reflected in this manual.
Federal law restricts this device to use only on the order of a physician.
• 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 flammable
anesthetics. Risk of explosion can result.
• Power interruption will cause the BLANKETROL II to revert to CHECK
SETPOINT resulting in no therapy to the patient. Follow instructions for desired
mode to resume operation. Failure to resume therapy could result in
serious injury or death.

•Use distilled water only. Do Not Use De-Ionized water.
•Do not use alcohol. Alcohol may cause blanket deterioration.
•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.
• The repair, calibration, and servicing of the BLANKETROL II should be
performed by qualified Medical Equipment Service Technicians, Certified
Biomedical Electronics Technicians, or Certified Clinical Engineers familiar with
good repair practices for servicing medical devices, and in accordance with
instructions contained in this manual. Improper repair can result in damage
to the BLANKETROL II system and patient injury.
Before returning the BLANKETROL II to patient use after repairs, the FIRST TIME
SET-UP/SYSTEM TEST ROUTINE in Section 2 must always be performed. Improper
repair can result in damage to the BLANKETROL II system and patient injury.

• 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. Notify the
physician promptly of any change in patient status in 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 bony prominences, to prevent skin damage that may result.
• Do not place additional heat sources between the patient and blanket.
Skin damage may result.
• The area between the patient and the blanket should be kept dry to avoid injury to
patient.
• Use only 400 Series, or equivalent, probes on CSZ equipment. Failure to do this
will cause incorrect temperature readings.
