3M™ Bair Hugger™ Warming Unit Model 775
Operator’s Manual
Introduction
Description of the 3M™ Bair Hugger™ Temperature
Management System
The Bair Hugger temperature management system consists of
a Model 775 warming unit (with optional rolling cart and other
accessories) along with a 3M™ Bair Hugger™ warming blanket or
3M™ Bair Hugger™ warming gown.
The 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.
This manual includes operating instructions and warming unit
specifications for the Model 775 warming unit. You can use the Model
775 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 blankets
or gowns with the Model 775 warming unit, refer to the respective
Instructions for Use.
Indications for use
The Bair Hugger family of temperature management systems are
indicated for hypothermic patients or normothermic patients for
whom induced hypothermia or localized temperature therapy is
clinically indicated. In addition, the temperature management
systems can be used to provide patient thermal comfort when
conditions exist that may cause patients to become too warm or too
cold. The temperature management systems 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.
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 ischemic limbs.
WARNING: To reduce the risk of thermal injury:
• The Bair Hugger Model 775 warming unit has been
designed to operate safely ONLY with 3M disposable
warming products. 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 products.
• 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 allow the patient
to lie on the warming unit hose. Do not allow the warming
hose to directly contact the patient’s skin during warming
therapy.
• Do not leave neonates, infants, children and other
vulnerable patient populations unattended during warming
therapy.
• Do not leave patients with poor perfusion unmonitored
during prolonged 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 connect a torn or damaged warming blanket/gown
to the warming unit.
• 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 place the warming blanket/gown directly over a
dispersive electrode pad.
• Do not continue warming therapy if the red Over-temp
indicator light illuminates and the alarm sounds. Unplug the
warming unit and contact a qualified service technician.
• 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.
• 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.
• Use only the power cord specified for this product and
certified for the country of use.
• Do not allow the power cord to get wet.
