Page 4: Introduction
Description of the Total Temperature Management* System The Bair Hugger brand Total Temperature Management system consists of a Bair Hugger forced-air warming unit and disposable components, including Bair Hugger forced-air blankets and the 241* blood/fluid warming set, and Bair Paws* patient warming gowns. -
Page 5: Warnings
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. -
Page 6: Cautions
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. Monitor the patient’s temperature and cutaneous response every 10-20 minutes or according to institutional protocol and monitor the patient’s vital signs regularly. -
