Phototherapy is a therapeutic measure that uses phototherapy units, equipment that uses electromagnetic radiation (light) for the treatment of neonatal jaundice, to reduce the severity of neonatal hyperbilirubinemia. The administration of phototherapy depends on bilirubin levels, age of life, gestational age at birth, birth weight, cause of jaundice and the clinical condition of the newborn. An infant bilirubin phototherapy unit is a medical instrument generally consisting of 4 blue light tubes and 2 white light tubes, plus a cover or screen that protects the newborn in the event of tube breakage and ultraviolet light. The blue tubes are placed in the center and the white tubes on the sides. At present, these phototherapy lamps are made up of fluorescent bulbs and LEDs used for neonatal treatment.
