If the smaller
Temperature Puck
seems too close, it can be rotated 180 degrees, in which
case, add 3.5" to the markings on the long bar. In the example above, the 9.5 inch marking (6"
+ 3.5" = 9.5") would be used.
Temperature Pucks for each of the other three quadrants are set up in the same manner. The
fully assembled system is shown in
Figure 9 .
The vPad-RW test system is now configured mechanically, according to the Standard, to take
temperature and other measurements in the center of the radiant warmer and in the center of
each of the four quadrants of the mattress. It is now necessary to make the electrical
connections for each of the sensors.
As previously described, the large round ‘Puck’ represents a thermal mass imitating the infant
body in a radiant warming environment. This ‘Puck’ is made of aluminum with a black heat
absorbing coating, with a temperature sensor embedded in the aluminum block. In this
configuration, the temperature measured by the ‘Puck’ is specifically configured to test
radiant
warmers . For testing incubators , a Temperature Probe is inserted into the connector at the
center of each Puck. This Temperature Probe bypasses the thermistor in the Puck and elevates
the thermistor in the Probe to a position approximately 10 cm above the mattress, in
accordance with the Standard.
