Introduction
Description of the Total Temperature Management™ System
The 3MTM Bair HuggerTM brand Total Temperature Management system consists of a
Model 775 forced-air temperature management unit (with optional rolling stand, and other
accessories) and disposable components, including Bair Hugger forced-air blankets, 3MTM
Bair PawsTM patient warming gowns and the 3MTM 241TM blood/fluid warming set. You
can use the Model 775 temperature management unit in all clinical settings where the
patient may become too warm or too cold; including the operating room to provide patient
temperature management.
This manual includes operating instructions and unit specifications for the Model 775
temperature management unit. For information about using Bair Hugger blankets, Bair Paws
gowns, or the 241 blood/fluid warming set with the Model 775 temperature management
unit, refer to the “Instructions for Use” included with each of these disposable components.
Indications
The Bair Hugger Total Temperature Management system is intended to prevent and treat
hypothermia. In addition, the temperature management system can be used to provide patient
thermal comfort when conditions exist that may cause patients to become too warm or too
cold. The temperature management system can be used with adult and pediatric patients.
Contraindications
Do not apply heat to lower extremities during aortic cross-clamping. Thermal injury may
occur if heat is applied to ischemic limbs.
Warnings
1. Do not leave patients with poor perfusion unmonitored during prolonged warming
therapy sessions. Thermal injury may result.
2. The Bair Hugger temperature management unit has been designed to operate safely
ONLY with Arizant HealthcareTM disposable components. Use with other products
may cause thermal injury. (To the full extent permitted by law, the manufacturer
and/or importer declines all responsibility for thermal injury resulting from the unit
being used in conjunction with non-Arizant Healthcare products.)
3. Do not warm patients with the temperature management unit hose alone.
Thermal injury may result. Always connect the hose to a Bair Hugger
blanket or Bair Paws gown before providing therapy.
4. Do not place the non-perforated side of the blanket on the patient. Thermal injury may
result. Always place the perforated side (the side with small holes) towards the patient.

Arizant Healthcare Inc.
5. Do not continue temperature management therapy if the Over-temp indicator light
illuminates and the alarm sounds. Thermal injury may result. Unplug the unit, and
contact a qualified service technician.
6. Do not continue 241 blood/fluid warming therapy if the Over-temp indicator light
illuminates and the alarm sounds. Immediately stop fluid flow, and discard the
blood/fluid warming set. Unplug the temperature management unit, and contact a
qualified service technician.
7. Do not use a forced-air warming device over transdermal medication. Increased drug
delivery and patient injury or death may occur.
8. Do not allow the patient to lie on the warming unit hose or allow the hose to directly
contact the patient’s skin during patient warming; thermal injury may result.
9. Equipment not suitable for use in the presence of a flammable anesthetic mixture
with air or with oxygen or nitrous oxide.
10. Reusable blankets made from woven fabric, or blankets without discrete, visible
holes, can cause the safety system of this unit to fail, which may result in serious
thermal injury. This warming unit has been designed to operate safety ONLY with
Bair Hugger blankets and Bair Paws gowns.
Cautions
1. Except for specific blanket models, Bair Hugger blankets are not sterile and are all
intended for single patient use ONLY. Placing a sheet between the Bair Hugger
blanket and the patient does not prevent contamination of this product.
2. Monitor the temperature and cutaneous response of patients who are incapable of
reacting, communicating and/or who are without a sense of feeling every 10-20
minutes or according to institutional protocol. Monitor the patient’s vital signs
regularly. Adjust air temperature or discontinue therapy when the therapeutic goal
is reached or if vital sign instability occurs. Notify physician of vital sign instability
immediately.
3. Do not leave pediatric patients unattended during therapy.
4. Do not initiate temperature management therapy unless the temperature management
unit is safely placed on a hard surface or securely mounted. Otherwise, injury may
result.
5. To prevent tipping, clamp the Model 775 temperature management unit to an IV pole
at a height that provides stability. We recommend clamping the unit no higher than
44" (112 cm) on an IV pole with a minimum 28" (71 cm) diameter wheelbase. Failure
to do so may result in IV pole tipping, catheter site trauma, and patient injury.
