Bair Hugger Model 500/OR Temperature Management Unit Operator’s Manual 3
Introduction
Description of the Total Temperature Management System
The Bair Hugger brand Total Temperature Management system consists of a Bair Hugger forced-air
temperature management unit (with available rolling stand and sheet clip) and Bair Hugger disposable components, including forced-air blankets and the 241* blood/fluid warming set. The system is
intended for use in all clinical settings including the operating room.
This manual includes operating instructions and unit specifications for the Model 500/OR forced-air
temperature management unit. For information about using Bair Hugger blankets or the 241
blood/fluid warming set with Bair Hugger units, refer to the “Instructions for Use” included with
each of these disposable components.
Indications for Use
The Bair Hugger brand Total Temperature Management system is intended to prevent and treat
hypothermia and to provide warmth to cold or shivering patients. In addition, the system should be
used whenever conditions exist that could cause patients to become cold.
Contraindications
Do not apply heat to lower extremities during aortic cross-clamping. Thermal injury may occur if
heat is applied to ischemic limbs.
Warn ings
• Do not use Bair Hugger units with any forced-air blanket or cover other than Bair Hugger
blankets. Thermal injury may result.
• Do not warm patients with the Bair Hugger unit hose alone. Thermal injury may result. Always
attach the hose to a Bair Hugger blanket before providing skin surface warming therapy.
• Do not continue therapy if the Over Heat warning light illuminates and the audible alarm sounds.
Thermal injury may result. Turn the temperature management OFF and contact qualified technical
personnel. If using 241 fluid warming, immediately stop fluid flow and discard the fluid warming set.
Precautions
• Monitor the patient’s temperature at least every 10 to 20 minutes, and monitor the patient’s vital
signs regularly. Reduce air temperature or discontinue therapy when the therapeutic goal is reached
or if vital sign instability occurs. Notify physician immediately of vital sign instability.
• To prevent suffocation from misuse, do not leave children or infants unattended when administering
Bair Hugger therapy.
• See CONTRAINDICATIONS and WARNINGS before administering therapy. Read this
Operator’s Manual, blanket instructions and 241 fluid warming set package instructions before use.
