OPERATION AND TECHNICAL MANUAL
Cincinnati Sub-Zero Products, LLC., reserves the right to make equipment changes and improvements, which
may not be reflected in this manual.
Failure to properly monitor patient may result in serious injury or death.
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 integrity of areas in
contact with blanket; also, check the Micro-Temp
®
LT’s water temperature. Pediatric patients,
temperature-sensitive patients with vascular disease, surgical patients, diabetics and patients with
Raynaud’s Disease are at greater risk for developing tissue injuries, and this should be considered
when selecting the temperature, duration of therapy and frequency of skin checks. Notify the
physician promptly of any change in patient status in order to avoid serious injury or death.
If device is used at home, patient must follow directions prescribed by their physician and be aware
of all warnings and cautions mentioned throughout the manual. Failure to do so may result in
patient injury.
Thermal injury may occur if heating/cooling blankets are used with a patient with an ischemic
limb.
Observe patient’s skin condition frequently due to individual differences in sensitivity and
susceptibility to injury from heat and/or externally applied chemicals or pressure. Patients at
greatest risk are those unconscious, on prolonged therapy, diabetics, children, and persons
incapacitated, with sensitive skin areas, or poor circulation. Failure to do so may result in
patient injury.
Do not use for ECMO (Extracorporeal Membrane Oxygenation) therapy as patient injury
may occur.
The method of temperature control provided by all localized heat therapy units presents the danger
of heating body tissues, particularly the skin, to a point where they are injured, i.e., burns. The
clinician is responsible for determining the appropriateness of the temperature limits in
dependency to time. Exceeding 40°C water temperature for extended periods can cause tissue
damage and burns. Clinical judgment should be used to determine the safe maximum contact
periods based on patient age, clinical condition, and current medications. Depending on the
extent and severity of a burn, very serious complications may arise.
Prevent excessive and/or prolonged tissue pressure and shearing forces, especially over bony
prominences. Failure to do so may result in tissue injury.
Do not wrap pad so tightly as to constrict blood flow. Patient injury may result.
Do not use pins to secure pad or hoses. Do not allow pad or hoses to come in contact with any
sharp object. Water leak may occur, and water leaks could lead to electric shock and/or
infection.
Do not place additional heat sources between the patient and pad. Skin damage may result.
Improper repair and inadequate maintenance can result in damage to the MICRO-TEMP
®
LT
system and patient injury.
Any time water is found leaking into or around the unit, connecting hose, and/or pad, turn the unit
off, disconnect the power cord from its power source, and correct the problem before proceeding.
Proper maintenance procedures should be followed including, but not limited to, the preventative
maintenance described in this manual. Leaky blankets or hoses should never be used. Water
leaks could lead to electric shock.
