neoBLUE® LED PHOTOTHERAPY OVERVIEW
Natus’ neoBLUE LED Phototherapy System is a floor-standing, mobile phototherapy device that delivers a narrow
band of high-intensity blue light via blue light emitting diodes (LEDs) to provide treatment for neonatal hyperbilirubinemia in the hospital setting. Blue LEDs emit light in the range of 400 – 500 nm (peak wavelength 450 - 470 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 ultraviolet (UV) or infrared (IR) radiation, so they
can be placed close to the baby.
STEPS FOR USING THE neoBLUE LIGHT ON A PATIENT
1. Per hospital protocol or at least every 6 months, check light intensity. LEDs have very gradual degradation of intensity
over time. A typical LED panel will provide over 4,000 hours of intensity above 30 µW/cm2/nm* with a total of 10,000 hours of
life (intensity above 12 µW/cm2/nm*). When intensity drops below the desired level, biomedical engineering can adjust it via the
potentiometer on the side of the enclosure. (Refer to service manual)
*As measured by a neoBLUE® Radiometer at 12 inches (30.5 cm) from the baby.
2. Shield infant’s eyes with appropriate protective eye shields.
3. Position light over infant. 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 can be tilted by grasping the device on
either side and adjusting to desired angle.

Tilting the light enclosure
When adjusting the proximity, hold up the neoBLUE light enclosure with one hand to lessen the weight on the rail.
4. Note hour count on timer. If you track patient treatment time, note the number of hours at the beginning of treatment, and
again at the end of treatment.

5. Turn on power switch on front of light enclosure. This is the
green switch in the center of the front panel.

6. Press Target Illumination Switch to center light over infant.
Confirm placement of the light to cover maximum surface area
of the baby for best results. The target light is red and should
be centered over the baby’s torso.
7. Per physician order, select High or Low intensity at
Irradiance Level Control Switch. Depending on your hospital
protocol, high may correspond with “double” or “triple” phototherapy.
Low typically corresponds to “single” phototherapy.

The neoBLUE light is calibrated at the factory with the neoBLUE® Radiometer
to yield the following intensities at 12 inches (30.5 cm) from the baby:
High intensity: 30-35 µW/cm2/nm
Low intensity: 12-15 µW/cm2/nm
Different radiometers will yield different measurements. Some radiometers are
calibrated to broad band light sources (e.g., white light) and will not register high
intensity with a narrow band blue light. Refer to the chart below for more
information on what your radiometer may read if you are not using
a neoBLUE® Radiometer.

NOTE: Vents are located on the
underside of the enclosure. Do not
block vents when using drapes or
other light shielding methods.
Intensity is inversely related to distance from the infant. As the neoBLUE light
does not emit significant UV or IR, it can be placed as close to the infant as
desired to yield high intensity levels. Likewise, biomedical engineering can
adjust the intensity as noted in the service manual.
When placing the light at an angle, you may be increasing the distance between
the light and the baby, thereby decreasing the intensity. In most cases, the
intensity will still be in the effective range. However, biomedical engineering
can adjust the intensity as noted above.
Use with an Incubator
The neoBLUE light can be placed on
top of an incubator with or without the
rollstand. The rubber feet on the bottom of the enclosure add stability and
room for air flow.

Use with a Radiant Warmer
When used with a radiant warmer,
care must be taken to angle the light
and position it to the side of the heat
source. The enclosure must be placed
no further than 12 inches (30.5 cm)
from the baby and out of the path
of the radiant heat source.
Use with a Bassinet
The neoBLUE light can be used to
treat babies in bassinets. Keep the
light as close to the baby as possible
to reduce convective heat loss caused
by traffic in the nursery. The neoBLUE
light drape can also be used to reduce
draft and lessen the light to caregivers.
Note: The neoBLUE drape is not
indicated for use in conjunction
with a radiant warmer.
Use only a light drape designed
specifically for the neoBLUE light.

Important! Though the neoBLUE
device does not radiate significant
heat, it is an electrical device and can
affect the temperature within a closed
environment. Use of patient servo
mode is indicated to control the baby’s
temperature during use. If manual
mode is prescribed, the baby’s temperature must be monitored.
The neoBLUE light can also be tilted
on the side of the incubator. Care
should be taken to protect caregivers from any glare by angling the light
towards the back of the room or by
using a drape.

FREQUENTLY ASKED QUESTIONS
• How often should I check the intensity? LEDs can last for thousands of hours at high intensity. Natus recommends checking
intensity at least every 6 months. When the intensity drops below the desired level, biomedical engineering should be called
to trim the potentiometer as noted in the service manual.
Checking the light intensity before each use is recommended where feasible to confirm correct positioning of the light over
• How often do we need to change the bulb? The LED panel will show slight degradation over time. After biomedical engineering adjusts the potentiometer to its maximum output, you will still have thousands of hours of use left. The panel will not shut
off at any time. The intensity will gradually decrease so the hospital has time to decide when to replace the panel.
• Should we turn off the light when we take a blood sample or assess the infant? You may choose to turn off the device while
providing direct infant care or assessment. The amount of time the blood will be exposed to the light is minimal but assessment
will be easier under natural lighting.
• What should we do if caregivers do not tolerate blue light well? A small percentage of the population has sensitivity to blue
light. Do not gaze into the LEDs. Use the neoBLUE light in a well-lighted area, angle the light away from ancillary work areas,
and/or use amber glasses or draping where necessary. The neoBLUE light drape is available from Natus. Guard Dog Bones
glasses (P/N 413BB) are recommended and are available online at www.safetyglasses.com or via phone at 1-800-870-6189.
• How far should the neoBLUE light be placed from the baby? The light is calibrated to deliver the stated intensity at a
distance of 12 inches (30.5 cm) from the baby. You can place the neoBLUE light closer as it does not emit significant UV or IR.
If you place it farther from the baby, you may need to trim the potentiometer to maintain high intensity. In general, for every
foot you move away from the baby, you halve the intensity.
• What is the red target light used for? To assess where the middle of the light is for proper placement.
• To avoid overheating, do not cover vents. Clean filters once per month (see user manual).
• Do not place directly under radiant heat source.
• If you have additional questions, please refer to your user manual.
