INTRODUCTION
Device Description
The HotDog Patient Warming System consists of the HotDog Controller, reusable warming
devices (e.g., Warming Blankets, Warming Mattresses) and accessories. This manual includes
use and maintenance instructions and specifications for the HotDog Controller Model WC5X.
For information about HotDog warming devices and accessories, refer to the User Manual
provided with each device/accessory.
The HotDog Controller is designed to help maintain normothermia in patients before, during
and after surgical procedures and to help prevent unintended hypothermia. The system is
powered and controlled by an electronic control unit. Warming devices are powered at low
voltage, ensuring safety for patients and operators. Warming temperatures are controlled
automatically to user-selected levels, and over-temperature safety shut-offs are integrated into
the controller as well as into each warming device.
The HotDog Controller can be placed on a flat surface, mounted on an IV pole or suspended
from the OR table/gurney rail using optional hooks. The HotDog Patient Warming System can
be operated continuously to maintain uniform heat under or over the patient, depending on
which warming device/accessory is selected. It is the responsibility of the user to determine
whether warming is appropriate for each individual patient. The HotDog Patient Warming
System should not be used when clinical considerations indicate that warming of the patient is
not advisable.
Indications for Use
The HotDog Patient Warming System is intended to prevent or treat hypothermia and to
provide warmth to patients. The HotDog Patient Warming System should be used in
circumstances in which patients may not maintain a state of normothermia. The System is
intended primarily for use in hospitals and surgical centers including, without limitation,
operating, recovery, and emergency rooms and on medical/surgical floors.
Contraindications
DO NOT warm ischemic or non-perfused tissue; thermal injury may result. Examples
include tissue distal to aortic cross clamping, or when vasoconstrictive drugs would lead to
severe, prolonged vasoconstriction.
DO NOT warm patients receiving transdermal medication; increased drug delivery may
occur.
