GENERAL INSTRUCTIONS
USE UNDER THE DIRECT SUPERVISION OF A CLINICIAN.
1. Select the Warming Blanket size that is the best fit for your patient, covering as much of
your patient as possible.
2. Position the Blanket under, over, or around the patient as desired, with the black side facing
the patient. Make sure the patient is in contact with the sensor. Refer to Precautions and
Pressure Reduction for guidance.
3. If desired, use the included strap to help conform the Blanket to the patient.
4. Connect the yellow cable to the short yellow cable off the side of the Blanket by aligning both
red dots and pushing straight in. Do not twist!
5. Connect the opposite end of the yellow cable to the Controller by inserting it into a yellow
port with the red dot on the cable facing up.
6. Turn the Controller on to begin warming and select the desired temperature on the
Controller. The Blanket will take approximately 3 minutes to reach the selected temperature.
7. Monitor the temperature of the patient frequently during each case. Increase or decrease
the Blanket temperature gradually to maintain normothermia.
GUIDELINES FOR TEMPERATURE SELECTION
Start by using the 40°C (104°F) temperature setting. If the patient is becoming normothermic,
there is no need to increase the temperature. If you are not getting the desired results, you may
increase the temperature, following all precautions. However, when the Blanket is under the patient,
do not select a temperature above 40°C (104°F).
Use over-body warming instead of
under-body warming on patients
with any risk factors such as
dehydration, poor circulation, lack of
perfusion, or any illness that may
impact circulation. For dental
procedures, see page 9.

User Manual: HotDogTM Veterinary Controller Page 9
PRESSURE REDUCTION
 The Warming Blanket is not a pressure-reduction device. Steps must be taken to
mitigate heat-on-pressure situations when the Blanket is under the patient on hard surfaces,
surgery tables, or dental grates. Use a pressure-reduction device (such as the HotDog
Pressure Reduction Pad) between the Blanket and the hard surface.
 Longer duration procedures (approximately two hours or more) create greater risks. When a
patient remains in a single position for an extended amount of time, ischemia can occur at
points of elevated pressure, which can lead to tissue necrosis.
 Eliminate pressure points from occurring (especially at bony prominences) by appropriate
pressure reduction.
 Closely monitor the temperature selection. Start by using the 40°C/104°F temperature
setting. If the patient is becoming normothermic, there is no need to increase the
temperature. If you are not getting the desired results, you may increase the temperature,
following all precautions.
 Use over-body warming instead of under-body warming on patients with any risk factors
(“Risk Factors”) such as dehydration, poor circulation, lack of perfusion, or any illness that
may impact circulation. (Note: for dental procedures, see below.)
 Hard objects should not be placed between the patient and the Blanket.
 If a rigid cautery ground plate is used, ensure that adequate steps are taken to mitigate
pressure. Do not place the cautery plate on the sensor area of the Blanket.
DENTAL PROCEDURES
Although the System is particularly useful in dental procedures, clinicians should take a few extra
precautions to protect the patient:
 Most importantly, ensure that the patient is in contact with the sensor at all times during the
case. Follow the temperature selection and pressure-reduction guidelines.
 Place a towel under the patient’s mouth/head to absorb dental fluids and to reduce drainage
onto the Warming Blanket. Make certain that the patient’s body is not lower than the head.
 There is no need to place a sheet, towel, or other barrier between the patient and the
Blanket.
 You may wrap the Blanket around the patient. However, when the Blanket is under the
patient, do not select a temperature above 40°C/104°F.
 Use over-body warming instead of under-body warming on patients with any risk factors such
as dehydration, poor circulation, lack of perfusion, or any illness that may impact circulation.
 The Blanket is not a pressure-reduction device. Steps must be taken to mitigate heat-
on-pressure situations when the Blanket is under the patient on hard surfaces, surgery
tables, or dental grates. Use a pressure-reduction device (such as the HotDog Pressure
Reduction Pad) between the Blanket and the hard surface.
CLEANING THE CONTROLLER
Warnings
 Do not immerse the Controller in liquid. Moisture will damage the components, and thermal
injury may result.
Precautions
 Do not use pure harsh solvents (e.g., MEK, acetone, etc.) to clean the Controller.
 Do not expose to hydrogen peroxide.

User Manual: HotDogTM Veterinary Controller Page 10
Frequency
 Per institutional protocols.
Tools/Equipment
 Sponge or soft cloth
 Mild detergent or anti-microbial spray
 Dry soft cloth
Method
1. Disconnect the Controller from the power source before cleaning.
2. Wipe the Controller with a moistened sponge or soft cloth; avoid pushing fluids into any
openings.
3. Dry with a separate soft cloth.
FAQ- Frequently Asked Questions
1. How does HotDog warming work? HotDog Warming Blankets use a conductive polymer
ThermAssure fabric. A low voltage DC current flows over this light, flexible fabric, and the
resistance generates even warmth. Blankets do not contain carbon fiber or ink, which could
break and create hot spots.
2. Why is HotDog warming safe? HotDog’s Controller is really a microprocessor with many
built-in safety features. It monitors connected warming devices at the patient and will
automatically stop operation if readings are outside of safe parameters. The Blankets use a
low-voltage, floating, isolated DC current to warm. The flexible conductive polymer fabric
generates uniform heat with no hot spots.
3. Why do HotDog Blankets expire? Over time, the electric current flowing over the
conductive polymer fabric oxidizes it, changing its resistance and the time it needs to reach
temperature. When new, it only takes a few minutes to reach the set temperature. After
approximately24 months of use, the Blanket will take longer to reach the set temperature.
We have no data to support the use of the devices beyond 24 months.
4. Are the Blankets difficult to clean? Cleaning takes 30 seconds or less. Blankets can be
cleaned by wiping with an approved cleaner. Do not use cleaners that contain hydrogen
peroxide. Do not use abrasive cleaners. The non-porous outer shell contains an anti-
microbial, and the edges are heat-sealed to eliminate crevices.
5. What cleaners are approved? The following may be used: Alcohol, Sodium Hypochlorite
(bleach), Chlorhexidine Gluconate, and Ammonium Chloride-based solutions. Follow your
facility’s cleaning protocols. Do not use Hydrogen Peroxide-based cleaners. Do not use
cleaning products that are abrasive.
6. How do I get the best warming results? BODY SURFACE AREA: Warm as much surface
area as possible. Warming the core is more effective than the periphery. SENSOR CONTACT:
Ensure that the sensor is in contact with the patient.
7. What temperature should I select? Start by using the 40°C/104°F temperature setting.
Monitor the temperature of your patient frequently during each case. Increase or decrease
the blanket temperature gradually to maintain patient normothermia. Do not use any
temperature above 40C/104F when the Blanket is positioned under the patient.

User Manual: HotDogTM Veterinary Controller Page 11
8. What type of barrier should I use? No barrier between the patient and the Blanket is
necessary.
9. How do I manage pressure reduction? See Pressure Reduction on page 9. Ensure that
pressure is mitigated for patients with any risk factors such as dehydration, poor circulation,
lack of perfusion, or any illness that may impact circulation. Use a pressure-reduction device
(such as the HotDog Pressure Reduction Pad) between the Blanket and the hard surface to
eliminate pressure points from occurring, especially at bony prominences.
10. How do I select Blanket size? See page 3. There are 5 Blanket sizes. Select the size that
is best fits the patient. Cover the most surface area of the patient.
11. How do I position the Blanket? The Blanket can be positioned over, under, or wrapped
around the patient. However, when the Blanket is under the patient, do not select a
temperature above 40°C/104°F. Cover the most surface area of the patient without
interfering with the procedure area. The patient should always be in contact with the sensor
on the black side of the Banket. Use the Blanket strap to secure.
12. Can the HotDog system be used in x-ray? Yes. The heater fabric is completely
radiolucent. However, the Blanket has parallel busbars that run along the long edges. These
can be seen on x-ray. The area around the sensor is also radio opaque. Position the Blanket
so that the imaging area does not contain the sensor or busbar.
ERROR CODES: Alerts & Alarms
If an Alarm or Alert condition occurs, the associated error code will remain on the display A or B
indicating that the blanket connected to the corresponding port has an issue until the condition is
resolved.
After the Alarm or Alert condition has been displayed, the display will return to the main operating
screen where the error code will still be present on the screen in place of the temperature set point.
To resolve an Alarm, follow the instructions shown on the next page. The Blanket will not be active
when an Alarm is occurring.
Automatic Shutoff Timer - This feature prevents the System from unintentionally being left
on. The System is not intended for use without a clinician present. The System defaults to a
6-hour shutoff. If there is no interaction with the Controller within 6 hours, it will automatically shut
off.

equipment and the HotDog Veterinary Patient Warming System
The HotDog Veterinary Patient Warming System is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The user of the HotDog Veterinary Patient Warming System can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and
the HotDog Veterinary Patient Warming System as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in
metres (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
