50/pkg) to monitor the
patient's skin temperature. Use of other manufacturer's probes
may affect the accuracy of warmer operation and the electrical
safety of the patient.
WARNING: The skin temperature probe should be located on the
patient's skin in an area which is directly in the path of the radiant
heat. It should not be attached to an area which is shielded from the
radiant heat or between the patient and the mattress. Large tem-
perature gradients and very long servo response times will result
from improper probe placement.
WARNING: Rectal temperatures must never be used to servo
control a patient's temperature.
The Ohmeda Patient probe lead is made from low mass wire that
helps prevent probe detachment while reducing pulling on the
neonate's skin.
Place the metal side of the skin temperature probe on the skin over
the liver area of the infant's abdomen. Remove the paper protecting
the hypoallergenic adhesive on the Heat Reflective Patch. Secure the
skin temperature probe to the patient's skin with the adhesive side
of the patch (Figure 3-2). Do not remove the heat reflecting foil which
must be facing up.
Note: The probe jack is attached at a specific torque value. Loosening
or tightening the jack may break the electrical connector. See Figure
3-3.
If the patient is prone, place the skin temperature probe on the back,
where it will not be against the mattress. If the probe is between the
patient and the mattress, it will produce false readings.
WARNING: Intimate contact between the skin temperature probe
tip and the patient's skin must be maintained for accurate skin
temperature measurement. Underheating or overheating may
result from poor contact between the skin temperature probe and
the patient. Verify that the skin temperature probe is securely
attached to the patient at least once every half hour.

The skin temperature probe may be used to monitor the patient's
temperature in the manual mode but it does not control the radiant
heat energy level. See step 4 for skin temperature probe attachment.
Note: A patient placed in any warmer will normally develop tempera-
ture gradients with hotter and cooler areas. This is due to radiant
heat being applied above the infant, the cooling effect from the
mattress below the infant, the unequal skin cooling effect from
evaporative water loss, unequal internal heat generation within the
patient, and the environmental variables of room temperature, room
air movement, incidental sunlight, etc.
