The Bair Hugger brand Total Temperature
Management System was developed by an
anesthesiologist to prevent and/or treat the
common but significant problem of hypothermia.
Examples of current applications for Bair Hugger systems
are post anesthesia care units (PACU), recovery rooms,
operating rooms, emergency departments, obstetrical
suites, and intensive care areas.
The warming unit draws ambient air through a filter and
warms the air to the specified temperature. It then
delivers the warmed air through a hose to the Bair Hugger
blanket over the patient.
When used properly, the Bair Hugger blanket distributes
the warm air around the patient’s body, creating a warm
environment.
This manual describes how to service Bair Hugger
warming units, and includes maintenance instructions
and specifications. Instructions for use can be found in
the Operation Manual, and instructions included with
Bair Hugger blankets and
