WARNING:
w
Do not use the Warmer in the presence of flammable anesthetics; a
possible explosion hazard exists under these conditions.
w
Radiant energy can adversely affect blood components. When using
intravenous tubing systems for delivery of blood components to patients
occupying a warmer, shield any tubing with aluminum foil.
w
When using a radiant warmer, change the patient’s diapers frequently. Radiant
energy causes more rapid urine evaporation, and may lead to inaccurate urine
diagnosis test analysis and inaccurate weight measurements.
w
Do not touch the protective grill under the radiant heater or the top of the
heater assembly. These surfaces may be hot and a burn could result.
w
Always set the caster brakes before placing a patient in the warmer.
1. Connect the power cord to a properly grounded AC power source.
2. Place the power switch in the On position. During the first seconds of operation, the
warmer performs a self check of the control system. The software is verified,
calibration is checked and operation of the solid state relay controlling the heater is
verified. All displays and indicators are lit and the audible alarm is sounded. If the
self check detects a failure, the alarm stays on and service is required.
Note: The Warmer begins operation in the Manual Mode, described in Step 3. To
operate the warmer in the Servo Mode, refer to the Servo Mode Operation in Step 5.
3. Manual Mode Operation.
WARNING:
w
Use the servo mode unless the manual mode is specifically prescribed.
While both modes require patient monitoring, the manual mode requires
constant attention. In the manual mode, you must take the responsibility
for making heater adjustments or environmental changes in response to
the following conditions:
• patient size and weight;
• bed to heater head height differences;
• changes in the environment (drafts, direct sunlight, phototherapy lamp
usage, etc.);
• changes in the patient condition
In the servo mode, the warmer automatically adjusts heater output to
maintain the desired skin temperature, reducing (but not eliminating) the
need to monitor the patient and make environmental adjustments to
ensure adequate patient temperature.
In the manual mode of operation, an operator prompt tone and the flashing of the
% power display prompt you to select a level of radiant heat.
Use the increase (
M
) or decrease (
?
) touch switch to adjust the % power in 5%
increments. The % power display indicates the power level selected. You must
select a % power level each time the warmer is switched to the manual mode.
When you select % power levels between 30% and 100%, a check patient alarm
sounds after 12 minutes to remind you to monitor the patient temperature. After
checking the patient, this alarm can be reset by pressing the alarm silence switch.
