INTRODUCTION
Device Description
The Hot Dog Patient Warming System consists of the Hot Dog Controller, reusable warming
devices (e.g., Warming Blankets, Warming Mattresses) and accessories. This manual includes use
and maintenance instructions and specifications for the Hot Dog Controller Model WC5X. For
information about Hot Dog warming devices and accessories, refer to the User Manual provided
with each device/accessory.
The Hot Dog 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 userselected levels, and over-temperature safety shut-offs are integrated into the controller as well as
into each warming device.
The Hot Dog 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 Hot Dog 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 Hot Dog Patient Warming System should
not be used when clinical considerations indicate that warming of the patient is not advisable.
Indications for Use
The Hot Dog Patient Warming System is intended to prevent or treat hypothermia and to provide
warmth to patients. The Hot Dog 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 patients during aortic cross-clamping; thermal injury may result.
DO NOT warm patients with ischemic or non-perfused limbs; thermal injury may result.
DO NOT warm patients receiving transdermal medication; increased drug delivery may
occur.

WARNINGS
General
EXPLOSION HAZARD – DO NOT use the Hot Dog Patient Warming System in the
presence of flammable anesthetics or highly oxygen-enriched environments such as
hyperbaric chambers, oxygen tents, etc.
Caution should be taken when using electric warming devices with HF surgical instruments
or endocardial catheters in respect to potential equalization.
Inspect Hot Dog components prior to use for signs of damage or excessive wear such as
cuts, holes or loose electrical connections. If signs of wear are evident, do not use the product
until it is inspected by technical staff.
DO NOT continue to use the Hot Dog Patient Warming System if the over temperature
indicator and/or alarm continue to sound after reset. Refer to the “Alarm” section of this
manual for more information.
Warming Blanket
DO NOT place Hot Dog Warming Blankets under the patient. The Warming Mattress and
Disposable Sheets are the only accessories designed for use under the patient.
Warming Mattress
The Warming Mattress is not sterile. Take appropriate precautions, as necessary, to protect
the sterile field.
Accessories and Other Equipment
Accessories and cables other than those specified in Hot Dog User Manuals may result in
increased emissions or decreased immunity of the Hot Dog Patient Warming system.
The Hot Dog Patient Warming System should not be used adjacent to or stacked with other
equipment. If adjacent or stacked use is necessary, carefully observe the Hot Dog Patient
Warming System to verify that it operates normally in this non-recommended configuration.
CAUTIONS
Federal law (USA) restricts this device to sale by or on the order of a licensed healthcare
professional.
User Manual: Hot DogTM Patient Warming System Controller Page 5
PRECAUTIONS
General
Use under the direct supervision of a clinician.
Monitor the patient’s vital signs regularly during warming according to institutional protocol.
If vital sign instability occurs, notify the clinician.
Care should be taken when using multiple warming methods.
The risk of skin irritation caused by pooling of surgical prep solutions under the patient may
increase with warming; ensure that surgical prep solution instructions for use are followed.
Warming Mattress
Ensure that the Warming Mattress is securely fastened to the table.
The use of gel pads between the Warming Mattress and the patient is not recommended; gel
pads may cause a loss of warming performance.
Always use a patient barrier between the patient and the Warming Mattress.
Care should be taken to alleviate or remove the risk of heating skin under pressurized bony
prominences.
Care should be taken to place the patient’s body in contact with the labeled sensor on the
Warming Mattress.
DO NOT use operating table clamps or similar devices on the Warming Mattress as they may
cause damage to the product and result in loss of the heating function and/or localized heat
build-up in the damaged area.
DO NOT place the Warming Mattress over a table joint that will move during surgery.
DO NOT use on OR tables wider than 20 inches (50.8 cm).
DO NOT use the Warming Mattress as a stand-alone patient pressure relief system.
DO NOT place any hard objects (e.g., mattress cables, EKG cables, hard cautery return pads,
patient fluid lines, etc.) between the Warming Mattress and patient’s body.
DO NOT fold or wrinkle the Warming Mattress during use as localized heat build-up may
occur in the overlapped area.
DO NOT use the Warming Mattress when pressure injury is a concern.
DO NOT X-ray or MRI through the white labeling or edges of the Warming Mattress.
DO NOT allow patient fluid lines to be placed between the Warming Mattress and Warming
Blanket or other warming equipment.
DO NOT position the patient’s head directly on the Warming Mattress.
DO NOT allow the heated side of a Hot Dog Warming Blanket to come in continuous contact
with the Warming Mattress when both devices are on.

PROPER USE AND MAINTENANCE
Do not open the Hot Dog Controller. There are no user serviceable parts. If service is required,
contact Technical Support (see page 15). The manufacturer assumes no responsibility for the
reliability, performance, or safety of the Hot Dog Patient Warming System if the following events
occur:
The Controller is disassembled or serviced by an unauthorized person.
The Patient Warming System components are used in a manner other than described in the
User Manuals.
The Controller is installed in an environment that does not meet the appropriate electrical and
grounding requirements.
The Controller is grounded and should not be attached to un-grounded tables intended for use
with a hyfrecator or equivalent devices.

User Manual: Hot DogTM Patient Warming System Controller Page 7
Mounting the Hot Dog Controller to an IV Pole
To mount the Hot Dog Controller to an IV pole, place the Controller IV pole adapter around the
IV pole and turn the clamp handle clockwise until securely tightened (Figure 1). To remove the
Controller from the IV pole, turn the clamp handle counterclockwise until the unit releases.
Caution
To prevent the IV pole from tipping, the Controller must be attached at a height that provides
stability. It is recommended to use an IV pole with a minimum wheelbase radius of 35.6 cm (14
in) and to mount the Controller no higher than 112 cm (44 in) from the floor. Failure to properly
mount the Controller may result in IV pole tipping, catheter site trauma and patient injury.

The Controller may also be suspended from the OR table/gurney rail using optional hooks
(Figure 2).
