Taking
Measurements
To use the Type B-22 sensor:
1
Connect the sensor to the readout.
2
Hold the sensor against the infant’s body as near to the umbilical as possible
and aim the sensor at the center of the phototherapy light (see Figure 7).
For reproducible measurements, always hold the sensor on the same place on
the infant’s body.
Changes in the distance or angle of the light to the patient will change the
irradiance the patient receives, requiring new measurements to be taken.

When charting irradiance, note the type of radiometer used (e.g., Olympic
Bili-Meter) and sensor (e.g., Type B-22).
If more than one phototherapy light is being used on the infant, take separate
measurements for each light and chart each reading.
