Medi-Therm® III
Safety Precautions
1.0 Safety Precautions
Read and understand this operating manual and
all precautions listed below prior to using the
Medi-Therm III Hyper/Hypothermia Machine.
DANGER
Do not use the Medi-Therm III machine in
the presence of flammable anesthetics.
Risk of explosion can result.
WARNING
• If the patient’s temperature is not responding or
does not reach the prescribed temperature in the
prescribed time or deviates from the prescribed
temperature range, notify the attending physician
promptly. Failure to notify the physician
promptly may result in serious injury or
death.
WARNING
• Prevent excessive and/or prolonged tissue
pressure and shearing forces, especially over
boney prominences. Skin damage may result.
• Keep the area between the patient and the
blanket dry. Excessive moisture may result in
skin damage.
• Do not tip machine over without first draining
the water out and unplugging the power cord.
Damage to the machine or electrical shock
can result.
• Repairs should be performed by qualified
personnel such as certified biomedical electronics
technicians or certified clinical engineers familiar
with repair practices for servicing medical devices,
and in accordance with the Medi-Therm III Service
Manual. Do not attempt repairs to Gaymar
medical equipment unless you possess these skills.
Damage to the machine or malfunction
may otherwise result.
• Power interruption will cause the Medi-Therm III
machine to go into a standby mode, resulting in no
therapy to the patient. Follow instructions for
desired mode to resume operation. Failure to
resume therapy could result in serious injury
or death.
• When performing the PROBE CHECK (p. 18,
10.1.2, item 4), use a protective sheath on the
probe. Failure to use a sheath could result in
cross-contamination.
• A physician’s order is required for setting blanket
temperature and for continued use of equipment.
At least every 20 minutes or as directed by a
physician, check patient’s temperature and skin
condition of areas in contact with blanket; also,
check blanket water temperature. Pediatric,
temperature-sensitive, and operating room
patients should be checked more frequently.
Failure to monitor patient may result in
skin damage or inappropriate patient
temperature.
• Avoid placing additional heat sources between
the patient and blanket. Skin damage may
result.
(continued next column)
CAUTION
• Fill with distilled water only. Failure to use
distilled water may result in poor machine
performance. Do not use alcohol. Alcohol may
accelerate blanket deterioration. Do not operate
without water, since damage to internal
components may result. Do not overfill.
Overfilling may result in overflow because the
water in the blanket drains back into the machine
when the machine is turned off.
• Place a dry absorbent sheet between the patient
and the blanket when using all-vinyl blankets.
Moisture may accumulate which may
result in skin damage.

2.0 Description
This manual describes the operation of the
Medi-Therm III Hyper/Hypothermia machine.
The Medi-Therm III Hyper/Hypothermia machine
provides a means of regulating patient temperature by
supplying temperature-controlled water through a
connector hose to a Gaymar Hyper/Hypothermia
blanket. The companion blanket provides the interface for
heating or cooling the patient. A patient probe senses
patient temperature.
www.gaymar.com P/N 11027-000 9/00
The Medi-Therm III machine, Hyper/Hypothermia
blanket, connector hose, and patient probe comprise the
Medi-Therm III system (fig. 1).
