Product Description of the 3M™ Bair Hugger™
Temperature Management System
The Bair Hugger temperature management system consists of
a Model 675 warming unit (with optional rolling cart and other
accessories) along with a 3M warming blanket or a Bair Hugger
warming gown.
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 unit and flows through the warming unit hose into the blanket or
gown. Depending on the model, the 3M blanket or gown is placed
either over, around or underneath the patient. Small perforations
on the blanket or gown allow the warm air to be dispersed over the
patient’s skin.
This manual includes operating instructions and warming unit
specifications for the Model 675 warming unit. You can use the
Model 675 warming unit in clinical settings where the patient may
feel too warm or too cold; including the operating room to provide
patient temperature management. For information about using 3M
Bair Hugger warming blankets or gowns with the Model 675 warming
unit, refer to the respective Instructions for Use.
Indications for Use
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 feel too warm or too
cold. The temperature management system can be used with adult
and pediatric patients.
The Bair Hugger temperature management system should only be
used by trained medical professionals.
Patient Population and Settings
Adult and pediatric patients being treated in operating rooms,
emergency departments and other departments in the hospital
setting where patient temperature management is required.
Contraindications, Warnings, Cautions and Notices
Explanation of Signal Word Consequences
WARNING: Indicates a hazardous situation which, if not avoided,
could result in death or serious injury.
CAUTION: Indicates a hazardous situation which, if not avoided,
could result in minor or moderate injury.
NOTICE: Indicates a situation which, if not avoided, could result in
property damage only.
CONTRAINDICATIONS
CONTRAINDICATION: To reduce the risk of thermal injury:
• Do not apply heat to lower extremities during aortic cross-
clamping. Thermal injury may occur if heat is applied to
ischemiclimbs.
WARNINGS
WARNING: To reduce the risk of thermal injury:
• The Bair Hugger warming unit Model 675 has been designed to
operate safely ONLY with 3M disposable warming blankets and
gowns. 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
warming unit being used in conjunction with non-3M warming
blankets and gowns.
• Do not treat patients with the warming unit hose alone. Always
attach the hose to a 3M warming blanket/gown before providing
warming therapy.
• Do not place the non-perforated side of the warming blanket/
gown on the patient. Always place the perforated side (with the
small holes) directly on top of the patient in contact with the
patient’s skin.
• Do not place the warming blanket/gown directly over a
dispersive electrode pad.
• For the Bair Hugger flex warming gown; ensure that the blood
pressure cuff, ECG, IV or other lines or cords are not between the
upper sleeve insert and the gown prior to deploying the upper
sleeve warming insert(s), as this could result in tearing of the
insert during deployment.
• For over-body warming blankets and gowns; do not place patient
securement device (i.e. safety strap or tape) over the warming
blanket/gown.
• For underbody or side channel warming blankets; if a securement
device (i.e. safety strap, tape) is used, ensure the warming
channels are not occluded.
• Do not allow the patient to lie on the warming unit hose.
• Do not allow the warming unit hose to directly contact the
patient’s skin during warming therapy.
• Do not connect a torn or damaged warming blanket/gown to the
warming unit.
• Do not leave patients with poor perfusion unmonitored during
prolonged warming therapy.
• Do not leave neonates, infants, children, and other vulnerable
patient populations unattended during warming therapy.
• Do not continue warming therapy if the red Over-temp symbol
illuminates and the alarm sounds. Unplug the warming unit and
contact a qualified service technician.
• Do not perform the over-temperature detection system test while
the warming unit is being used for warming therapy.
WARNING: To reduce the risk of patient injury or death due to
altered drug delivery:
• Do not use a warming blanket/gown over transdermal medication
patches.
WARNING: To reduce the risk of injury due to interference with
ventilation
• Do not allow the warming blanket/gown or head drape to cover
the patient’s head or airway when the patient is not mechanically
ventilated.
WARNING: To reduce the risk of injury due to patient falls
• Do not use a warming blanket/gown to transfer or move the
patient.
WARNING: To reduce the risks associated with hazardous voltage
and fire
• Keep power cord visible and accessible at all times. The plug on
the power cord serves as the disconnect device.
• Only connect to outlets marked “Hospital only,” “Hospital
Grade,” or a reliable grounded outlet.
