mask ( ), and detach the
nebulizer kit from the main
unit ( ).
4. Attach the mouthpiece (or mask) to
the cap ( ). You can directly
connect the nebulizer kit to the

INTENDED USE
SootheNeb NBL300g Compressor Nebulizer is designed to
provide a compressed air source to aerosolize physician-pre-
scribed liquid medication when used in combination with the
packaged nebulizer accessories, except for Pentamidine. For
reasons of hygiene, the packaged nebulizer accessories are
intended for single use by single patient. SootheNeb NBL300g
Compressor Nebulizer is intended for use with children and adult
patients in the homecare settings.
Caution: Federal law restricts this device to sale by or on the
order of a physician.
IMPORTANT INFORMATION ABOUT INHALATION THERAPY
The device is ideally suitable for inhalation at home or when
travelling. It guarantees highly effective, fast-acting inhalation
treatment for children and adult patients.
Carry out inhalation in a quiet and relaxed state, and inhale
slowly and deeply, so that the medication can penetrate into the
fine, deep bronchial tubes. Exhale normally.

IMPORTANT SAFETY PRECAUTIONS
● Use the equipment only for its intended use as described in
this instruction. Do not use attachments not recommended by
the manufacturer.
● Use the equipment with medications only under the instruction
of your physician.
● Do not use the equipment if it has any damaged parts, or it
has fallen into water.
● To use the equipment for the first time, or after storing it for an
extended period, be sure to clean all necessary parts as
described in the cleaning instructions.
● Do not use while bathing.
● The unit should not be left unattended while plugged in or
turned on.
● Keep the unit out of reach of small unsupervised children. The
small parts detached from the device may result children
choking from inhaling or swallowing.
● The accessible materials used in the device will not cause the
potential allergic reactions to skin.
● Do not try to modify the device to prevent any danger.
● Do not place the device in liquid, nor put it where it could fall
into liquid. If the device becomes wet, unplug the device
before touching it.
● Do not use the device if it is not working properly, or if it has
suffered any damage.
● Do not subject the nebulizer to any impact and do not drop it.
● After a period of no use, and after every use, please clean the
main unit.
● Do not expose the nebulizer to direct sunlight, high tempera-
tures or humidity.
START YOUR TREATMENT
Before Use
● Ensure that all parts are clean and dry.
● Before starting treatment, talk to your physician about the
duration, dosage and frequency of use of the nebulizer.
● The device is designed for an intermittent use: 30 minutes ON
/ 30 minutes OFF.
● Do not remove the nebulizer kit from the main unit during
nebulization.
● Pour the distilled water (2 - 5 ml) into the medicine cup. Press
the power button to turn on the device, check if the nebuliza-
tion is taking place properly. Then, press the power button to
turn off and discard any remaining water.
● The prescribed volume of the drug should be adhere to.
● The device does not heat up the medicine cup during opera-
tion, so there is no loss of solution due to evaporation.
How to Use
● Before first use, pull out the insulation
mylar embedded in the battery
compartment and recharge the main
unit for 5 hours. Suggestion for
using 5V / 2A power plug for
recharge.
● Once the nebulizer is plugged into the
power plug at any time, it will go into
recharge mode and stop nebulization.
1. Align the tab of the spray
nozzle with the notch of the
cap and assemble.
2. Add the appropriate amount
of medication to the medicine
cup, as directed by your
physician. Do not exceed
the line marked “MAX”.
3. Assemble the nebulizer kit.
● Turn clockwise, and the
junction of the nebulizer kit
will become one full circle.
● Align and insert the
assembled cap on the
medicine cup.

Recommended separation distance between
portable and mobile RF communications equipment and the device
The device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the
user of the device can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the device as recommended below, according to the maximum output power of the
communications equipment.
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be
estimated using the equation applicable to the frequency of the transmitter, where p is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.

Federal Communications Commission (FCC) Statement
This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC
rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communi-
cations. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of
the following measures:
● Reorient or relocate the receiving antenna.
● Increase the separation between the equipment and receiver.
● Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
● Consult the dealer or an experienced radio/TV technician for
help.
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions:
1. This device may not cause harmful interference and
2. This device must accept any interference received, including
interference that may cause undesired operation of the device.
FCC RF Radiation Exposure Statement:
1. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
2. This equipment complies with FCC RF radiation exposure
limits set forth for an uncontrolled environment. This equip-
ment should be installed and operated with a minimum
distance of 20 centimeters between the radiator radiation
source and your body.
ADDITIONAL INFORMATION
Particle Size Delivery Test according to EN13544:2007
The mass median aerodynamic diameter (MMAD), geometric
standard deviation (GSD), respirable fraction (%, 0.5-5 μm), and
particle size distribution of the particles generated from SootheN-
eb NBL300g Compressor Nebulizer are determined by laboratory
testing conducted with a cascade impactor method according to
the European Standard for nebulizers (EN 13544-1:2007).
Three different drugs were used in the testing to represent three
different drug classes: Ipratropium bromide (anti-cholinergic
bronchodilator), Ventolin (as known as albuterol, a beta-agonist
bronchodilator) and Cromolyn sodium (anti-inflammatory). The
dose of each drug that used at the beginning of the cascade
impactor testing was:
● Ipratropium: 500 ug / 2 mL
● Ventolin: 5000 ug / 2.5 mL
● Cromolyn: 8000 ug / 2 mL
The test had involved three runs each of three separate device
samples tested with three classes of drugs. The durations of
each sample collecting by cascade impactor is about 1 - 3 mins
to allow for maximum deposit on each stage without overloading.
The result summary of the test is shown in Table 1, CV (%) of
repeatability was less than 5%.

The ANOVA statistical analysis of the data from the performance
test has been applied in the data analysis. Results show that
there is no significant difference (p > 0.05) between the mass
size distributions of the medicine particles generated by the
proposed device and a legally marketed device (predicate
device).
In conclusion, the performance test results support the specifica-
tions of SootheNeb NBL300g Compressor Nebulizer, which has
mass-median aerosol diameter (MMAD) less than 5 μm and
respirable fraction range from 60% to 80% depends on the drug
type.
