Product Description
The warming system provides a means for treating or preventing hypothermia
in adult and pediatric patients in clinical settings. The warming system consists
of an electronic blower (warming unit) that delivers heated air through a flex-
ible hose to a lightweight blanket placed on the patient. The blanket distrib-
utes the heated air through numerous small perforations that allow the air to
reach the targeted areas of the patient’s body.

Features
•
Multiple Temperature Settings — A range of temperature settings allows the
clinician to customize and adjust treatment based on the patient’s needs.
•
Boost Mode — For rapid warming, air is generated at 47°C for 45 minutes, after
which the temperature automatically drops to the 45°C (High) temperature set-
ting.
•
HEPA Filter — A High Efficiency Particulate Air (HEPA) filter removes at least
99.97% of particles 0.3 micrometers or larger from the air delivered to the
warming blanket. The warming unit monitors the amount of time the filter is in
use and indicates when the filter needs to be replaced.
•
Automatic Over- and Under-Temperature Protection — At any of the
heated air settings, if the temperature of the generated air is out of range for a
specific amount of time, the heater and fan automatically shut off and an alarm
is issued.
•
Optional Cart with Wheel Locks — An optional transport cart, equipped with
wheel locks, is available for the warming unit. The wheel locks reduce cart move-
ment while the system is in use.
