WARNING
S Read and understand all information in this manual before using the Thermaltek 300 ”Plus” Portable
Warmer.
S Federal law (U.S.A.) restricts this device to sale by or on the order of a licensed health care professional.
S During warming therapy, the clinician is responsible for monitoring the patient’s condition. It is recom-
mended that the patient’s skin condition, body core temperature, and vital signs be monitored at a mini-
mum of 15 minute intervals. If monitoring does not occur, thermal injury may result, especially if the patient
has the following conditions:
a. Significant peripheral vascular disease (occlusive or diabetic).
b. Low cardiac output.
c. Totally immobilized/anesthetized.
d. Marginal cutaneous perfusion.
Do not use the High temperature setting (110_ F) if the patient has any of the conditions (a, b, c or d) listed
above.
Reduce air temperature or discontinue warming therapy when therapeutic goal is reached, vital sign instability occurs or if the patient’s skin condition is compromised in any way.
This warming system is not intended for use with other external warming devices.
S The Thermaltek ”Plus” Portable Warmer must only be used with a Thermaltek overlay. Use of any
other warming blanket may result in thermal injury.
S The Thermaltek overlay must only be used with the Thermaltek ”Plus” Portable Warmer. Using a Ther-
maltek overlay with any other warming unit may result in thermal injury.
S The temperature settings on the Thermaltek 300 ”Plus”:
High 110_ ± 5_ F (43_ ± 3_ C),
Medium 100_ ± 5_ F (38_ ± 3_ C),
Low 90_ ± 5_ F (32_ ± 3_ C),
are average temperatures at various points around the patient and under the overlay based on a specific
testing protocol. The actual temperature of the air at various points around the patient and under the overlay is determined by different factors including, but not limited to, ambient temperature and use of insulating blankets.
S The Thermaltek 300 ”Plus” Portable Warmer is equipped with an Automatic Temperature Step–Down
(ATS) feature (see page 9 for details) that automatically lowers the temperature from high to medium
after 20 minutes of continuous operation. A brief alarm sounds as the temperature changes. Manual resetting is required to select a new temperature. The ATS feature does not preclude the clinician from monitoring the patient’s skin condition throughout the usage of the warmer. The patient’s skin condition must
always be monitored at a minimum of 15 minute intervals to prevent patient injury.
S Inspect warmer for damage prior to use. If damage is present or warmer has been dropped, do not use
the warmer. Contact your Stryker Service representative.

INDICATIONS
For patient warming
CONTRAINDICATIONS
Do not apply heat to lower extremities during aortic cross–clamping. Thermal injury may occur if heat is applied to ischemic limbs.
1. Place the overlay directly on top of the patient, with the perforated side on the patient’s body.
2. Remove the cap from the hose. DO NOT operate the warmer with the dust cap on or without fully
extending the warmer hose.
3. If the hose is retracted, twist the connector to the left or right to align the four tabs. The hose will
spring out. Continue to pull out the hose until the inside connector is centered and the four tabs are
outside the warmer housing. Twist the hose or the inside connector to lock it in place.
4. To connect the hose to a warming overlay, select an inlet on the overlay. Remove the foam core from
the center of the inlet. Grasp the hose connector around the wide raised ridge. While holding the
inlet tab on the overlay, insert the hose, bottom first. Pull the overlay inlet firmly over the hose connector so the inlet covers at least the first ridge on the connector. (Pulling the inlet over the wide second ridge provides a more secure connection). If an overlay inlet is accidently opened, an adhesive
label is provided in the overlay package to re–seal the opening.
5. To maximize effectiveness, place a cotton blanket over the top of the overlay. Do not place sheets or
blankets between the overlay and the patient.
WARNING
S When using the full–body and lower–body overlays, the urethane hose connector must be positioned so
that the hose as it leaves the blanket is parallel to the center tubes of the overlay.
S When using the upper–body overlay, the urethane hose connector must be positioned so that the hose
as it leaves the blanket is perpendicular to the center tubes of the overlay.
S Position the warmer hose so that the air flow is not restricted.
S The perforated fabric–like side of the overlay must be placed against the patient’s skin to ensure safe
usage. Do not place the polyethylene side of the overlay next to the patient’s skin or thermal injury could
result.
S During warming therapy, the patient’s wounds should be covered. If the patient’s wounds are infected,
the possibility of airborne contamination should be considered.
S Before beginning warming therapy, be sure the patient is dry. If warming therapy is started on a wet pa-
tient, a cooling effect will occur.
S Warming overlays are not sterile and are intended for single patient use only. Placing a sheet between
the warming overlay and the patient does not prevent contamination. Re–use of the warming overlay may
cause cross–contamination.
S Do not sterilize the warming overlays. Materials have not been proven compatible with any sterilization
method. Ethylene Oxide sterilization may leave toxic residue on the warming overlay.
S To prevent suf focation from misuse, do not leave children or infants unattended when administering warm-
ing therapy.
S Avoid direct contact of a laser or an electro–surgical active electrode with overlay material to avoid pos-
sible ignition.

OPERATING WARMER (CONTINUED)
6. Plug warming unit into a properly grounded wall receptacle and ensure the power light comes on.
7. Activate the warmer by pressing the ONE TOUCH key or press an air flow and an air temperature
key to activate the desired settings.
NOTE
If the HI or LO key is pressed prior to the ONE TOUCH key, the warmer will not activate until a temperature
setting is selected.
8. Select the initial temperature setting based on the patient’s condition as per protocol.
Ambient air for mild cooling.
Low 90_ ± 5_ F (32_ ± 3_ C) long term therapy for temperature maintenance.
Medium 100_ ± 5_ F (38_ ± 3_ C) for immobilized/anesthetized patients or those with poor perfusion.
High 110_ ± 5_ F (43_ ± 3_ C) for patients who are moving all extremities and have normal lower
extremity cutaneous perfusion.
WARNING
The following maximum recommended temperatures may be used as a guide, however , the ultimate decision
is the responsibility of the attending physician. The patient’s skin condition, core temperature and vital signs
must be monitored every 15 minutes and the temperature adjusted accordingly.
Patient Condition Maximum Recommended Temperature
Aortic Cross–Clamping Do Not Apply Heat
Significant Vascular Disease (occlusive or diabetic) Medium
Low Cardiac Output Medium
Totally Immobilized/Anesthetized Medium
Marginal Cutaneous Perfusion Medium
WARNING
Monitor the patient’s core, axillary or skin temperature and skin condition at a minimum of 15 minute intervals
during the warming therapy. Reduce air temperature or discontinue therapy when the therapeutic goal is
reached, if vital sign instability occurs, or if the patient’s skin condition is compromised in any way. Notify
physician of vital sign instability immediately. Temperature in excess of the therapeutic goal may result from
failure to monitor the patient’s temperature every 15 minutes. See CONTRAINDICATIONS for patients who
should not receive therapy.
9. Following warming therapy, the hose can be tucked inside the warming unit and secured by twisting
the hose connector until it fits securely in the warmer housing. Seal the hose cap over the retracted
hose to prevent dust from collecting. The hose can also be stored in the extended position by attaching the end of the hose to the hose cap.
10. The hose can be removed from the warmer if it becomes damaged or soiled. Pull the hose out until
the inside connector is visible. Instead of centering the connector as for normal operation, turn it perpendicular to the warmer opening. Squeeze the connector to flatten it, align it with the opening
notches and remove it from the warmer. To reattach the hose perform these steps in reverse.

300 ”PLUS” PORTABLE WARMER SUPPORT POST
The ”Plus” Portable Warmer support post (item (D)
in the illustration below) is a dual diameter post
with multiple functions:
1. The support post is designed so it only fits into
the socket on the base one way. The warmer
rests securely in the socket on the warmer
base and allows the use of the top handle on
the warmer for moving the warmer around
while it is attached to the base.
2. The support post fits into either foot board socket on Stryker stretchers. Since the ”Plus” Portable Warmer only has one support post, it allows flexibility in placement.
3. The support post allows the warmer to be
placed in any standard 1/2” I.V. pole socket on
a stretcher or bed. Special adaptors that allow
the warmer to rest in larger I.V. sockets (5/8” –
1”) may also be purchased.
