1PRODUCT DESCRIPTION
The neoBLUE®Phototherapy System consists of two products – the neoBLUE LED
Phototherapy light source (light) and the neoBLUE LED Phototherapy roll stand.
Before assembling the neoBLUE light and administering phototherapy, read all sections of this
manual carefully. There are safety considerations that should be read and understood before
use.
Intended Use/Indications for Use
The neoBLUE LED Phototherapy System is indicated for the treatment of hyperbilirubinemia for
neonates and infants in a hospital environment, and administered by trained, professional
medical staff, on the order of a licensed medical practitioner. The light can be used with a
bassinet, incubator, open bed, or radiant warmer.
Contraindications
Congenital porphyria or a family history of porphyria is an absolute contraindication to the use of
phototherapy, as is the concomitant use of drugs or agents that are photosensitizers.1
Clinical Benefit
The clinical benefit to the patient is the degradation of bilirubin for the treatment of
hyperbilirubinemia.
Intended Patient Population
The terms “infant” and “baby” are used throughout this manual and both include the patient
population of neonates and infants.
When treating term and near-term neonates with intensive phototherapy for treatment guidance,
please refer to the AAP Guidelines (American Academy of Pediatrics Clinical Practice Guideline
– Management of Hyperbilirubinemia in the Newborn Patient 35 or More Weeks of Gestation).
When treating preterm neonates with intensive phototherapy, please seek guidance from
physician on duration of the treatment as well as appropriate patient monitoring.
Physical Characteristics
The neoBLUE LED Phototherapy System is a floor-standing, mobile phototherapy light that
delivers a narrow band of high-intensity blue light via blue light emitting diodes (LEDs) to
provide treatment for neonatal hyperbilirubinemia.
Light Source
The light consists of a lightweight plastic light enclosure. When used with the neoBLUE roll
stand, the light can be tilted and adjusted both horizontally and vertically on the roll stand
assembly. The light enclosure can be tilted to approximately 40° up from horizontal (the resting
position). The light enclosure height can be adjusted vertically along the roll stand post, as well
as horizontally out from the roll stand post (proximity adjustment) to aid in positioning the light.
To help position the light over the infant, a red target light can be briefly illuminated using the
right rocker switch on the front panel. The light can be used for infants in a bassinet, incubator,
open bed, or radiant warmer.
The light can be used independently of the roll stand. The light enclosure can be placed directly
on an incubator with a flat-topped surface.
1Subcommittee on Hyperbilirubinemia. American Academy of Pediatrics clinical practice guideline: Management of
hyperbilirubinemia in the newborn infant 35 or more weeks of gestation. Pediatrics. 2004; 114(1):297-316.

NOTE: Medical electrical equipment needs special precautions regarding EMC and needs to be
installed and put into service according to the EMC information provided in this document. See
Service Manual Chapter 7 Electromagnetic Specifications for details.
There are two intensity settings, high and low, to provide the physician the option to treat the
patient with intensive or standard levels of phototherapy. The desired setting is selected using
the left rocker switch on the front panel of the light. The light output was factory calibrated with
the neoBLUE®Radiometer to provide an initial intensity of 35 µW/cm2/nm at the high setting and
15 µW/cm2/nm at the low setting at a distance of 12 inches (30.5 cm) from the light enclosure to
the baby. The light output can also be adjusted using the two potentiometers (located on the
side of the light enclosure) to accommodate different distances. A lens panel protects the light
from incidental debris or fluid exposure.
Blue LEDs emit light in the range of 400 – 550 nm (peak wavelength 450-475 nm). This range
corresponds to the spectral absorption of light by bilirubin, and is thus considered to be the most
effective for the degradation of bilirubin. Blue LEDs do not emit significant energy in the
ultraviolet (UV) region of the spectrum, reducing the potential risk of skin damage. In addition,
blue LEDs do not emit significant energy in the infrared (IR) region of the spectrum, minimizing
concern about excessive warming of the infant. As with all phototherapy lights, protective eye
shields such as the Natus Biliband®Eye Protectors must be used to protect the infant’s eyes
from excessive light exposure.
LEDs have minimal light output degradation over their lifetime with proper use. Nevertheless,
the user can adjust the output of the LEDs for any degradation using the two potentiometers.
Life testing has shown neoBLUE LEDs can emit high intensity phototherapy for over 50,000
hours. Actual results may vary based on environmental factors and adjustments to the
potentiometers.
Timer
The neoBLUE light is equipped with a timer to track the total number of hours it is switched on.
The timer will count up to a maximum of 9999999.9 hours. The decimal point will be flashing at
a steady rate when the timer is counting. When the timer is not counting, the decimal point will
not flash. The timer will count any time the lighted green on/standby switch is in the on position.
The timer will count at the same rate regardless of the intensity setting at which the device is
being used. The last digit refers to tenths of hours, with 0.1 = 6 minutes. To reset the timer,
please refer to the service manual.
Phototherapy Roll Stand
The roll stand is designed to hold the neoBLUE light with a base designed to accommodate the
weight distribution of the light enclosure at any height or angle.
The roll stand operates on a gas shock to maintain a safe pole height during adjustments.
The roll stand incorporates features to adjust the height, tilt and proximity of the light source as
described in Section 3.1.
Power Requirement and Accessories
The light is mains-power operated. The power cord plugs into a receptacle at the power inlet at
the back of the light enclosure. There are no single-use components for the light.

Lighted Green On/Stand-by Switch
The lighted green switch (between the target light switch and the intensity switch) is used to turn
the device on or put it in stand-by mode. The switch should only be illuminated when in the on
position. When in the stand-by position, line voltage is still present inside the device if the device
is plugged in, but no DC voltage is being switched to the LED panel, fans or timer.
Accessory Pack
An accessory pack is included with each light enclosure. The accessory pack contains the
following items: a CD, a power cord, vent filters and extra thumb screws and mounting posts for
attaching the light enclosure to the roll stand.
2SAFETY INFORMATION

precautions to ensure the safety of the patient and those near the instrument. In addition, please
refer to your hospital policy and protocol for phototherapy administration.
NOTE: Refer to the jaundice management guidelines or regulations in your country to determine
best treatment path for neonatal hyperbilirubinemia; such as the AAP Guidelines (American
Academy of Pediatrics Clinical Practice Guideline – Management of Hyperbilirubinemia in the
Newborn Infant 35 or More Weeks of Gestation); or NICE guidelines (National Institute for
Health and Clinical Excellence – Neonatal Jaundice).
NOTE: Any serious incident that has occurred in relation to the device should be reported to
Natus Medical Incorporated and the competent authority of the Member State in which the user
and/or patient is established.
Warning! The neoBLUE device should be used only by appropriately trained personnel
and under the direction of qualified medical personnel familiar with currently known risks
and benefits of neonatal phototherapy equipment use.
Warning! Incorrect use of the light, or the use of parts and accessories that are not
manufactured or supplied by Natus Medical Incorporated, can damage the light, and may
cause injury to the patient and/or user.
Warning! Select only infants for whom phototherapy has been prescribed.
Warning! The intensity level and duration of treatment should be prescribed by the
physician for each patient.
Warning!Intensive phototherapy (≥30 µW/cm2/nm), may not be appropriate for all
infants (i.e. preterm infants ≤1000g).2
Warning! Do not modify the equipment in any way that is not consistent with instructions
in the user manual or service manual.
Warning! Placement directly on incubator: The enclosure can be placed on flat

neoBLUE®LED Phototherapy System User Manual
Page 7 of 22
Warning! Placement directly on incubator: The use of skin-controlled mode (patient
servo) of the incubator or radiant warmer is recommended unless manual mode (air
servo) specifically prescribed. While both modes require patient monitoring, manual mode
requires constant attention. In manual mode, care must be taken to observe any changes in
ambient conditions (drafts, sunlight, phototherapy light usage, etc) as small changes can
have an effect on patient temperature. While patient servo also requires attention, the radiant
warmer is designed to keep the patient’s skin temperature controlled, reducing (but not
eliminating) the need to monitor the patient. In addition, use of reflective foils may cause
hazardous body temperatures. Monitor the infant’s skin temperature per your hospital
protocol during phototherapy to avoid fluctuations in body temperature.
Warning! Use with Radiant Warmer: Do not place the neoBLUE light directly under
radiant heat source.
Warning! Attachment of Light Enclosure: When attaching the light to any floor stand
other than the neoBLUE roll stand, confirm weight capacity and stability of the stand.
(Section 8).
Warning! Monitor infants regularly during treatment per your institution’s protocols. Use
the following guidelines:
•Measure the patient’s bilirubin level periodically.
•Turn the unit off when checking the baby’s condition and visualizing skin color; blue light
can hinder clinical observations by masking skin color changes, such as cyanosis.
•Monitor patient temperature and fluid status, especially when used with thermotherapy.
•Periodically verify that the baby’s eyes are protected and free of infection.
Warning! Eye Protection: Do not look directly into the LEDs. During treatment, always protect
the baby’s eyes with eye shields or equivalent. Periodically and/or per your hospital protocol,
verify that the baby’s eyes are protected and free of infection. Patients adjacent to the light may also
need to be protected with eye shields or equivalent.
Warning! Eye Protection: It is important to select the appropriate size of eye protection for
neonates and infants to ensure proper fit and prevent slippage. Refer to the instruction that comes
with the eye protector for proper fit.
Warning! Skin Temperature: The use of skin-controlled mode of the incubator or
radiant warmer is recommended. In addition, use of reflective foils may cause hazardous
body temperatures. Monitor the infant’s skin temperature per your hospital protocol during
phototherapy to avoid fluctuations in body temperature.
Warning! Heat Supply: The light may impact the heat supply in thermotherapy devices
(incubators, radiant warmers, or heated mattresses) and the patient’s body temperature.

6ROUTINE CLEANING AND MAINTENANCE
6.1 Checking the Light Intensity
It is recommended that the intensity of the light be checked before each use to ensure the light
is providing the intended dose of treatment as prescribed by the physician. This measurement is
taken at the central area of the effective surface area for phototherapy.
neoBLUE Radiometer
Natus Medical Incorporated recommends using a properly calibrated neoBLUE Radiometer for
measuring the intensity of the neoBLUE light. If this meter is not available, it is important to
measure the intensity with a radiometer specifically designed to measure the narrow wavelength
spectrum of blue LEDs. Radiometers designed to measure the broadband spectrum found in
fluorescent or halogen lights will result in inaccurate intensity measurements.
If the intensity measured falls below factory settings or hospital minimums due to degradation or
increased distance, have a qualified technician test the intensity level and readjust the intensity
to achieve the desired output, if required
NOTE: The intensity of the light is inversely related to the distance from the light source to the
infant. Therefore, the intensity can also be adjusted for by moving the light closer or further from
the infant.
NOTE: The intensity of the light is not adversely affected if a few LEDs burn out. The LEDs are
installed in groups of six, so failure of a single LED normally causes six to fail.

neoBLUE®LED Phototherapy System User Manual

6.2 Adjusting the Light Intensity
There are two intensity settings, high and low, to provide the physician the option to treat the
patient with intensive or standard levels of phototherapy. The desired setting is selected using
the left rocker switch on the front panel of the light. The light output was factory calibrated with
the neoBLUE Radiometer to provide an initial intensity of 35 μW/cm2/nm at the high setting and
15 μW/cm2/nm at the low setting at a distance of 12 inches (30.5 cm) from the light enclosure to
the baby. The light output can also be adjusted using the two potentiometers (located on the
side of the light enclosure) to accommodate different distances or compensate for any
degradation of the LEDs. Please refer to the Service Manual for instructions on how to adjust
the light output.
If the desired intensity output cannot be attained after several adjustments of the
