But the practice is to be better safe than sorry. Absorbency Units is a reference scale for calibrating the spectrophotometer. A Hitachi U-200 spectrophotometer was used for diagnostics. Comparison Phototherapy Statistics Bilirubin is dynamically distributed in the blood and many tissues. Specifically, it is held in subcutaneous fat where the greater the surface area exposed to phototherapy, the faster will be the decline of bilirubin.
Evidence comes from a clinical trial comparing traditional banked lights with a Fiberoptic device.
Treatment time using the larger surface area exposed was about half as long as the treatment time required with the Fiberoptic lights. When a home care provider studied length of treatment they found that while using the most popular devices they found that the banked lights took about half as many days to bring the bilirubin levels down to desired levels as the Fiberoptic style. This study was looking at the cost effectiveness of home phototherapy treatment and incidentally found that fully diapered infants screened enough body surface area to account for the low daily decrement of bilirubin levels. A non-woven front sheet, clear poly back sheet and the superabsorbant core padding provide the patented design in our diaper. No latex is used in any of the materials.
