Introduction
Description of the 3M™ Bair Hugger™ Temperature
Management System
The 3M™ Bair Hugger™ temperature management system consists of a
Model 775 warming unit (with optional rolling stand, and other accessories)
along with a 3M warming blanket, Bair Hugger warming gown, or the 3M™
Ranger™ 241 blood/fluid warming set.
The Bair Hugger warming unit is attached to the warming blanket or
warming gown by means of a flexible hose. Warm air is generated in the
warming unit and flows through the warming unit hose and into the blanket
or gown. Depending on the model, the 3M blanket or gown is placed
either around, over, or underneath the patient. Small perforations on the
blanket or gown allow the warm air to be dispersed over the patient. For
blood/fluid warming applications, the Model 241 blood/fluid warming
set is inserted in the warming unit hose. When the warming unit is turned
ON and a temperature setting is selected, warm air flows over the Model
241 tubing and warmed blood/fluid exits from the distal end of the tubing.
For additional information on 3M blankets, gowns, the 241 warming set, or
other accessories visit us online at bairhugger.com.
This manual includes operating and service instructions and warming unit
specifications for the Model 775 warming unit. The warming unit can be
used in all clinical settings where the patient may feel too warm or too
cold. For information about using 3M blankets, gowns, or the 241 blood/
fluid warming set with the warming unit, refer to the respective Instructions
for Use.
Indications

that may cause patients to feel too warm or too cold. The temperature
management system can be used with adult and pediatric patients.
