Description of skin temperature regulation

This chapter describes skin temperature regulation in incubator operation and in
radiant warmer operation.
Skin temperature mode
Skin temperature mode can be used in incubator operation and radiant warmer
operation. Two skin temperature sensors can be connected. The yellow skin
temperature sensor measures the central skin temperature. The optional white skin
temperature sensor measures the peripheral skin temperature. In skin temperature
mode, only the measured value from the yellow skin temperature sensor is used for
the regulation of the radiant warmer (radiant warmer operation) and the convection
heater (incubator operation). Only the yellow skin temperature sensor is used for
skin temperature regulation.
Skin temperature regulation in incubator operation
The measured central skin temperature is compared with the defined set value for
the skin temperature and regulated accordingly. The set value for the skin
temperature can be set to between 34 and 38 °C (93.2 and 100.4 °F). The
difference between the defined set value and the measured actual value for the skin
temperature regulates the air temperature in the device.
If the defined set value is greater than the measured value (skin too cold), the
convection heater receives a signal to increase the heat. The air temperature inside
the device increases.
If the defined set value is lower than the measured value (skin too warm), the
convection heater receives a signal to decrease the heat. The air temperature
inside the device decreases.
Skin temperature regulation in radiant warmer operation
The heating level is regulated based on the difference between the defined set
value for the skin temperature and the measured central skin temperature. For a set
value range between 34 and 38 °C (93.2 and 100.4 °F), the device regulates the
output power of the radiant warmer in such a way that the difference between the
set value and measured value is minimized.
If the defined set value is greater than the measured value (skin too cold), the
radiant warmer receives a signal to increase the heat. The radiant warmer power
increases and the patient receives more heat.
If the defined set value is lower than the measured value (skin too warm), the
radiant warmer receives a signal to decrease the heat.
