6.6.3 Automatic intensity reduction
Under certain circumstances at radiation intensity above 10 mW/cm² infants can suffer from hyperthermia.
Therefore the radiant warmer provides an automatic intensity reduction which reduces the intensity to the a
safe value (factory setting 10 mW/cm²) after 15 minutes.
The factory set default value 10 mW/cm², to which the intensity is automatically reduced after
15 minutes, can be changed to 8; 6; 4 or 2 mW/cm², as described in chapter 7.2.
When an intensity above 10 mW/cm² was selected and confirmed, it is in
the extended selection range and the colour of the LED spot (11.4) is
changed from green to orange. After confirming a selection within the
extended range a second, green LED spot (11.5) lights up. The position of
this LED spot corresponds to the default value after switching on the
heating (factory setting 10 mW/cm²) and indicates the value to which the
intensity is automatically reduced after 15 minutes.
Furthermore the balance time to the next automatic reduction is indicated
above the selected and actual intensity display (11.8).
When the indicated balance time has elapsed, the intensity is automatically reduced to the intensity indicated
by the green LED spot (11.5). This is indicated by alternating flashing of the orange LED spot (11.4) for the
intensity selection and the greed LED spot (11.5) for the reduced value and a yellow flashing background of
the balance time display (11.8) and signalized by an audio alarm of medium priority.
Now check the patient's temperature and reduce the intensity selection if necessary. If the treatment in the
increased intensity range shall be continued, this must be confirmed by keypress (4). The audio alarm is
paused and the radiant warmer will supply the selected intensity for further 15 minutes. The orange LED spot
and the green LED spot as well as the yellow background of the balance time display stop flashing and the
balance time starts again at 15 minutes.
When the patient shall stay under the radiant warmer for longer time at an
intensity above 10 mW/cm² a surveillance of his body temperature is re-
commendable. When a continuous surveillance is guaranteed, the safety
function >10 mW/cm² can be switched-off temporarily by a conscious
action. For this purpose press key (4) for approx. 3 seconds until two
short tones sound and the balance time display (11.8) is replaced by a
yellow symbol .
When the safety function >10 mW/cm² shall be reactivated, press key (4) again for approx. 3 seconds
until one short tone sounds. The yellow symbol is replaced by the balance time display again and
15 minutes to the next reduction start to elapse.
The automatic intensity reduction must never be deactivated if the temperature surveillance of the
patient is not secured.
When the heating is switched-on anew, or after an intensity of 10 mW/cm² or lower was selected, in
principle the safety function is activated.
