3.2 Manual and Servo Mode Operation
WARNING:
w
Before using the Ohmeda Infant Warmer System, read this entire manual.
Attempting to use this device without a thorough understanding of its
operation may result in patient or user injury. This device should only be
operated by personnel trained in its operation and under the direction of
qualified medical personnel familiar with the benefits and risks of this
type of device.
w
Do not leave the patient unattended when using the Infant Warmer. Check
the patient’s temperature periodically using an independent temperature
monitoring device to ensure the comfort and the safety of the patient. If
the warmer is used for an extended time, it is recommended that the
servo mode of operation be used. When an alarm is silenced, close
monitoring of the patient’s condition is required.
w
Use of electrosurgical units or other electrical field radiating equipment
can affect the operation of the Warmer. Keep the patient probe lead as far
away as possible from electrosurgical cables. Do not allow excess electri-
cal cables to be laid on the bed platform. Use of electrosurgical units or
other instruments which radiate electrical fields can cause indirect heat-
ing, by several tenths of a degree of the skin temperature probe due to
absorbed electrical energy. When using these devices near the radiant
warmer, operate the Warmer in manual mode for maximum safety.
w
The use of phototherapy equipment may raise the patient’s temperature.
w
Radiant warmers increase an infant’s insensible water loss. Take appro-
priate measures to maintain the patient’s fluid balance while caring for
them in a radiant warmer.
