The intensity selection is mainly dependent from the baby's respectively the patient's weight, age, maturity,
the anamnesis as well as the ambient conditions. When the radiant warmer is used for long-term care, the
radiation intensity has to be selected with utmost care.
•
The smaller and immature the infant, the higher is the heat demand.
•
The lower the ambient temperature, the higher is the heat demand.
If there is no experience regarding the intensity selection, for an unclothed infant 10 mW/cm² should be
selected initially. The body temperature must be checked in regular intervals. If necessary, the intensity
selection must be adjusted according to the measured patient temperature.
The intensity selection is ideal when neutral thermal conditions are available, i.e. when the patient's body
core temperature in relaxed condition is between 36.7 and 37.3°C.
Under certain circumstances radiation intensity above 10 mW/cm² may bring an infant in a hyperthermic
condition. Therefore the radiant warmer provides the following automatic safety function which is indicated
by the yellow warning lamp (10):
When radiation intensity above 10 mW/cm² is emitted to the patient pad for more than 15 minutes, the
radiation intensity is automatically reduced to 10 mW/cm² and an alarm is released.
In the intensity selection display (12) the LED spot for the selection and the LED spot for 10 mW/cm² flash
alternately and a short alarm tone sounds in intervals of 2 seconds. Check the patient's temperature and
reduce the intensity selection if necessary. When the patient shall stay under the radiant warmer at an
intensity selection above 10 mW/cm², push button (4). Now the alarm is reset and the radiant warmer will
emit the selected intensity for further 15 minutes. The yellow warning lamp (10) lights and indicates that the
safety function >10 mW/cm² is activated.
The intensity selection refers to the patient pad. The radiation intensity reaching the patient's skin is
approx. 4 mW/cm² higher than the selected value because the distance of the radiant warmer to the
patient's body surface is approx. 10 cm shorter than to the patient pad.
When the patient shall stay under the radiant warmer for longer time at an intensity above 10 mW/cm² it is
recommendable to survey the body temperature, e.g. with temperature monitor APGAR DIGITEMP order
No. WY1004. In that case the safety function >10 mW/cm² can be switched-off temporarily by a conscious
action. Push button (4) for approx. 3 seconds until two short tones sound and the warning lamp (10) flashes.
When the safety function >10 mW/cm² shall be reactivated, push button (4) again for approx. 3 seconds until
one short tone sounds. The warning lamp (10) stops flashing. It lights when in case of intensity selection
>10 mW/cm² the safety function >10 mW/cm² is switched-on.
When the radiant warmer is switched-on anew, the safety function is always activated.
Maximum intensity
Depending on the device model and the calibrated distance to the patient pad a maximum intensity of 14 to
30 mW/cm² can be selected. (refer to "Technical Data", page 20, as well as the data under the individual
mounts, pages 21 to 24).
In case of a selection which the radiant warmer is unable to reach, the maximum intensity is indicated by a
permanent LED spot in display (12). The unreachable selection is indicated by a flashing LED spot. In that
case reduce the intensity selection to the reachable value by turning the knob (13) anti-clockwise.
