Care of the Skin Important clinical information – please read carefully before using this device. The skin serves as a protective barrier against chemical, mechanical, and biological insults. The skin is also important in the regulation of body temperature and serves as a route of water excretion, especially in premature infants. The introduction of new intensive-care techniques has been associated with the increased survival of very small, premature infants. The immaturity of the skin of the very low weight infants, coupled with excessive instrumentation and handling, poses previously unrecognized problems for the nursing care of these infants.1 Please read, evaluate and implement the following recommendations as appropriate: 1. Please refer to the following standard of skin care recommendations as given in the literature2 when utilizing this device with all infants. Special attention should be given to sanitation and skin integrity. Observe color, rashes, excoriation Clean skin with warm water Clean perineal area after stooling Change infant’s position every 2 hours 2. This device is intended only for the treatment of existing hyperbilirubinemia. Use of this device for prophylactic treatment, particularly of premature infants, is not recommended. These infants have extremely fragile skin3 and various clinical studies have produced inconsistent conclusions concerning the effectiveness of prophylactic phototherapy treatment. 4, 5

Chapter 1 Product Description Intended Use The BiliSoft LED Phototherapy System provides light therapy for the treatment of indirect hyperbilirubinemia, commonly known as neonatal jaundice, in a hospital or home setting.
Description The BiliSoft LED Phototherapy System consists of a light box and a detachable fiberoptic light pad with a long, flexible fiberoptic cable. The fiberoptic cable delivers light from a high intensity LED module in the light box to the fiberoptic light pad. The flexible fiberoptic light pad is placed in a soft BiliSoft Pad Cover or BiliSoft Nest that is then brought into contact with the patient’s skin. The patient is exposed to light in the wavelength of 430-490 nanometer range (peak 440-460 nanometer). Units are available with two fiberoptic pad sizes: large (25cm x 30cm) and small (15cm x 30cm). The large pad’s nominal spectral irradiance is 35 µW•cm-2•nm-1 through a typical BiliSoft Pad Cover or BiliSoft Nest. The small pad’s nominal spectral irradiance is 50 µW•cm-2•nm-1 through a typical BiliSoft Pad Cover or BiliSoft Nest.

General Safety Information WARNING: Eye Protection: Direct exposure of the eyes to any phototherapy light may cause eye damage. Always protect the baby’s eyes with eye patches or an equivalent appropriate eye protection product. Periodically and/or per your hospital protocol or healthcare provider’s instructions, verify that the patient’s eyes are protected and free of infection. Care should also be taken to protect the eyes of patients adjacent to the treatment area, when necessary. WARNING: Home Users: During phototherapy treatment always follow your healthcare professional’s care instructions. WARNING: Caregiver Side Effects: Looking at light emitted by any phototherapy device for prolonged periods may cause side effects, such as headache, nausea, or mild vertigo, in some caregivers or visitors. WARNING: Bilirubin Levels: The bilirubin levels of patients receiving phototherapy should be regularly measured. WARNING: Possible Risks: All phototherapy methods have possible risks including, but not limited to apnea, bronze baby syndrome, diarrhea, hyperpigmentation-reddening, patent ductus arteriosus, riboflavincalcium and other deficiencies, skin blistering, skin irritation and thrombocytopenia. Monitor the patient closely for signs of these conditions during phototherapy. WARNING: Porphyrins/Photoisomers: Bilirubin photoisomers may cause toxic effects. Porphyrins are the by-products of the photochemical break down of the bilirubin molecule. In some cases, exposure of porphyrins to phototherapy may result in a localized reddening of the patient’s skin. Therefore, skin assessment is recommended with all types of phototherapy. WARNING: Photosensitive Drugs: The light generated by phototherapy devices can degrade photosensitive medications. Do not place or store any drugs near or in the illuminated area.
2-3
WARNING: Water Loss: The radiant energy from phototherapy lights can increase a patient’s insensible water loss. Take appropriate measures to maintain the patient’s fluid balance while administering phototherapy. WARNING: Skin Temperature: Phototherapy light can affect the temperature in thermoregulation devices (incubator, radiant warmers or heated mattresses) and may raise the patient’s body temperature. It is recommended to use the incubator or warmer in skin controlled (servo) mode. Always monitor the patient’s temperature to avoid temperature fluctuations during phototherapy. WARNING: Reflective Foils: Using reflective foils to increase the efficacy of phototherapy may cause hazardous patient body temperatures. WARNING: Combustible Gases: Do not use the BiliSoft LED Phototherapy System in the presence of gases that support combustion like oxygen, nitrous oxide or other flammable or combustible anesthetics. WARNING: Flammable Solutions: Never use flammable solutions to clean the BiliSoft LED Phototherapy System or any of its parts. CAUTION: Medical Electrical Equipment needs special precautions regarding EMC and needs to be installed and put into service according to the EMC information provided in the service manual. Portable and mobile RF communications equipment can affect Medical Electrical Equipment. The BiliSoft LED Phototherapy System should not be used adjacent to or be stacked on other equipment. If adjacent or stacked use is necessary, the BiliSoft LED Phototherapy System should be observed to verify normal operation in the configuration in which it will be used.

Chapter 3 Home Use Homecare provider Ensure when you deliver BiliSoft LED Phototherapy System for use in the home that you provide adequate in-service training for parents or guardians. Be sure to provide this Operation Manual and eye covers.
Parents or Guardians Ask your healthcare provider for information about monitoring your baby during the phototherapy treatment. Follow your doctor’s recommendation for treatment duration. Before you begin treatment, place the following items close to the treatment area:
Phone numbers of doctor, hospital and home healthcare provider Thermometer Extra BiliSoft Covers or BiliSoft Nests
To properly operate the unit, follow the steps described in "Using the Unit" in Chapter 5 of this manual. Position your baby according to your doctor’s recommendations. Ensure that as much of the baby’s skin as possible is in direct contact with the illuminated section of the covered light pad. The baby, along with the light pad, may be covered or wrapped in a thin blanket. It is possible to hold and feed the baby while continuing treatment. The baby will continue to receive effective phototherapy treatment as long as the covered, light emitting section of the pad remains in direct contact with the skin. You may swaddle the baby. Cover the baby’s eyes when using the BiliSoft LED Phototherapy System to shield them from light emitted by the BiliSoft fiberoptic light pad. WARNING: Direct exposure of the eyes to any phototherapy light may cause eye damage. Always protect the baby’s eyes with eye patches or an equivalent appropriate eye protection product. Periodically and/or per your hospital protocol or healthcare provider’s instructions, verify that the patient’s eyes are protected and free of infection. Care should also be taken to protect the eyes of patients adjacent to the treatment area, when necessary.

Recording Daily Activities You should keep a daily record of your baby’s activities and condition. A sample of an easyto-use chart is provided on the following page. These records will provide your healthcare provider or physician with an accurate account of your baby's activities, enabling them to better assess the progress being made.
Taking Temperatures It is important to monitor your baby’s temperature during phototherapy sessions. Your doctor will tell you the range of acceptable temperatures for your infant and may suggest a method for taking temperatures. For charting purposes, it is important that you use the same method each time you take your baby's temperature.
Urine/Stools It is essential that you count and record the number of stools and wet diapers. You will also be asked to describe stools. Loose stools, black or dark green sticky stools are common during phototherapy. These observations will help your healthcare provider determine if your baby is getting enough fluids and will signify any significant changes in their condition. On your record sheet, note occurrences under the appropriate column and describe the stools.
Feeding Follow your baby’s regular feeding schedule. Your healthcare provider can help you determine this. Note feeding times and amount of formula taken, or length of time fed, on the record sheet.
Treatment Time Your healthcare provider or physician will tell you how long your baby needs to undergo treatment. Record the actual times at which your baby is put on and taken off the BiliSoft LED Phototherapy System during each 24-hour period. Apply phototherapy for as long as possible during each 24-hour period.
Bathing You may continue your baby's normal bathing routine. Discontinue phototherapy during bathing. WARNING: If you have questions or concerns, contact your healthcare provider immediately.
