Introduction
Description of the Total Temperature Management*System
The Bair Hugger brand Total Temperature Management system consists of a Model
750 forced-air temperature management unit (also available with rolling stand and sheet
clip) and disposable components, including Bair Hugger forced-air blankets, Bair Paws*
patient warming gowns and the 241* blood/fluid warming set. You can use the Model
750 temperature management unit in all clinical settings including the operating room to
provide patient temperature management.
This manual includes operating instructions and unit specifications for the Model 750
temperature management unit. For information about using Bair Hugger blankets, Bair Paws
gowns or the 241 blood/fluid warming set with the Model 750 temperature management
unit, refer to the “Instructions for Use” included with each of these disposable components.
Indications
The Bair Hugger 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
Do not leave patients with poor perfusion unmonitored during prolonged warming1.
therapy sessions. Thermal injury may result.
The Bair Hugger temperature management unit has been designed to operate safely2.
ONLY with Arizant Healthcare* 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.
Do not place the non-perforated side of the blanket on the patient. Thermal injury4.
may result. Always place the perforated side (that is, with small holes) towards the
patient.
Do not continue temperature management therapy if the over-temp indicator light5.

Failure to do so may result in IV pole tipping, catheter site trauma, and patient injury.
m e t h o d
To mount the Model 750 temperature management unit to an IV pole, simply turn the
clamp handle clockwise to tighten the clamp on the IV pole and counterclockwise to
release it. See Figure D.

Viewing the Temperature Mode Timer
The temperature mode timer records the amount of time the temperature management
unit has been operating in the selected temperature mode. The timer resets itself every time
you select a different temperature mode.
To view the temperature mode timer, press the button for the current temperature mode,
and hold it for 2 seconds. The alphanumeric display will show the temperature mode time,
then go back to showing the temperature mode setting.
What to Do in Case of an Over-Temperature Condition
If an over-temperature condition occurs, the red Over-temp indicator light flashes and
an alarm sounds. The unit automatically turns the heater, blower, and operating mode
indicator lights OFF. The control panel will not respond to commands, but pressing any
button will silence the alarm.
i f a n o v e r -t e m p e r a t u r e c o n d i t i o n o c c u r s :

fluid warming system, immediately stop fluid flow and discard the blood/fluid
warming set.
Unplug the temperature management unit.2.
Contact a qualified service technician.3.
What to Do in Case of a Fault Condition
The Model 750 temperature management unit’s software recognizes several non-hazardous

sounds. The control panel will not respond to commands, but pressing any button will
silence the alarm.
