Section 1 - Safety Precautions
1.0 Safety Precautions
Review the following SAFETY PRECAUTIONS
prior to using the Power Unit. These SAFETY
PRECAUTIONS appear within this manual, the
Power Unit label, or the Quilt Instructions for Use.
DANGER
!
• Explosive hazard. Do not use in the
presence of flammable anesthetics.
• Risk of electric shock. Disconnect power
before servicing the TC3146 Power Unit.
WARNING
!
This device generates heated air flow.
Excessive heat could cause thermal
stress or skin lesions. Failure to follow
these precautions could result in death or
serious injury:
• Use the Convective Warming System
only under direction of a physician. A
physician's order is required for setting
temperature and for continued use of
equipment.
• If the patient's temperature is not
responding or does not reach the
prescribed temperature in the prescribed
time, or deviates from the prescribed
temperature range, notify the attending
physician promptly.
• Monitor core temperature. Neonates and
pediatric patients of low weight will have
a tendency to overheat more readily than
adults. Failure to monitor core temperature
could result in abnormal elevation of body
temperature resulting in death or serious
injury.
• Monitor the patient's temperature, vital
signs, and skin condition regularly
(every 20 minutes or as prescribed by
a physician). Pediatric, temperature-
sensitive, and postoperative patients
should be checked more frequently.
If the patient's temperature is within
the prescribed range, select a lower
temperature setting or discontinue therapy.

WARNING
!
If vital signs become unstable, notify the
attending physician immediately.
• Do not apply heat to lower extremities
during aortic cross-clamping. Ischemic
injury may occur.
• Do not apply heat to ischemic tissue.
• Do not use the Power Unit unless the
hose is connected to a warming quilt.
Place your hand under the quilt to verify
the air is warm.
• Use this Power Unit only with those quilts
recommended by the manufacturer (see
inside cover of this manual for list).
• Repairs should be performed only by
qualified personnel such as certified
biomedical electronics technicians or
certified clinical engineers familiar with
repair practices for servicing medical
devices, and in accordance with the
Service Manual. Damage to the Power
Unit or malfunction could otherwise
result.
CAUTION
!
• U. S. Federal law restricts this
device to sale by or on the order of a
physician.
• Evaporative cooling may result if the
patient's skin is not dry.
• Do not permit air from the quilt to blow
onto an open wound. Convective airflow
can cause airborne contamination to
open wounds. Use tape on quilt to restrict
movement of air toward the surgical site.
• For grounding reliability, plug only into
a grounded outlet labelled "Hospital
Grade."
• When using an I. V. pole, do not mount
the Power Unit higher than 3 feet
(0.9 meter). Otherwise, the Power Unit
could tip over.
