Safety Features
The AoVest was designed with maximum safety in mind,
therefore it contains the following safety features:
Motors operate at safe, low voltages.
Controller contains a fuse in the event of electrical
problems.
The controller operates on a timer to ensure shut-o.
User Information
IMPORTANT
The AoVest should be worn over clothing or with a fabric
shield to prevent cross-contamination in a clinic or hospital
setting where more than one patient uses the unit. The
AoVest should be cleaned appropriately between patient
use, see the Cleaning the AoVest section.
According to the American Association for Respiratory
Care (AARC) Guidelines for Postural Drainage Therapy, the
decision to use the unit for airway clearance therapy (ACT)
requires careful consideration and a doctor’s assessment of
the individual patient’s case if the following conditions exist:
Intracranial pressure (ICP) greater than 20 mm Hg
Recent spinal surgery or acute spinal injury
Bronchopleural stula
Pulmonary edema associated with congestive
heart failure
Large pleural eusions or empyema
Pulmonary embolism
Acute illness
Pregnancy or nursing mothers
Electronic implants
Rib fractures, with or without ail chest
Surgical wound or healing tissue or recent skin grafts or
aps on the thorax
Uncontrolled hypertension
Distended abdomen
Recent esophageal surgery
Active or recent gross hemoptysis
Uncontrolled airway at risk for aspiration such as tube
feeding or a recent meal
Subcutaneous emphysema
Recent epidural spinal infusion or spinal anesthesia
Burns, open wounds and skin infections on the thorax
Recent placement of transvenous or subcutaneous
pacemaker
Suspected pulmonary tuberculosis
Lung contusion
Bronchospasm
Osteoporosis or osteomyelitis of the ribs
Coagulopathy
Complaint of chest wall pain

Indications for Use/Method/
Application
Indications for Use
The AoVest is intended for promoting airway clearance
and improvement of bronchial drainage by enhancing
mobilization of bronchial secretions where external
manipulation of the thorax is the physician’s choice
of treatment.
Method
The AoVest generates vibration and oscillation of the
user’s chest wall through integrated motor modules,
installed into various parts of the vest. The patient controls
the rate and frequency at which these motors oscillate the
thoracic region with the use of a controller attached to
the vest that can increase or decrease intensity to address
the volume of mucus present in the air pathways, in
compliance with a physician’s prescription and orders.
Application
The AoVest may be prescribed for one of these
conditions*:
Bronchiectasis
Cystic brosis
Late eects of poliomyelitis
Other deciencies of circulating enzymes
Anterior horn cell diseases
Multiple sclerosis
Quadriplegia
Muscular dystrophy
Myotonic disorders
Myopathies
Disorders of the diaphragm
* Not all conditions allow for insurance reimbursement;
contact your provider for details.
Unpacking and Using the AoVest
for the First Time
IMPORTANT
Please follow the steps in order to ensure proper set-up.
Battery must be fully charged before use (this is covered in
the steps below).
Step 1: Unpacking the AoVest

Step 2: Checking Battery Level and
Charging Battery
IMPORTANT
Use only the supplied rechargeable battery and the
supplied power supply to ensure safe and reliable
operation of the AoVest.
To check the battery level, depress the fuel gauge push-
button to activate the fuel gauge LEDs.
Battery level push button
The battery LEDs will light up to indicate the battery level:

0 –19% 20–39% 40–59% 60–79% 80–100%
To charge the battery, connect the power supply to a wall
outlet and plug the power supply into the battery port as
shown. The power supply LED will turn on when connected
to the wall outlet.
Power Supply LED lit
Next, plug the power supply plug into the AoVest
battery. There is a small opening at the bottom of the
battery pouch.
Power supply connected to battery
IMPORTANT
When the power supply is plugged into the battery, pay
close attention not to place any strain onto the power
supply cord. Rough handling of the vest and power
supply while plugged into the battery could cause
damage to the battery.
When the battery is charging, the LEDs will become
lit with one (1) LED blinking. Note, this may take 5–10
seconds for the LEDs to light after plugging in the
power supply.
It is recommended to allow the battery to fully charge for
at least three (3) hours and until all LEDs are solidly lit.
At the completion of charging, disconnect the power
supply from the battery. It is recommended that the
power supply be unplugged from the wall outlet and
stored until next use.
The battery gauge LEDs will remain lit for approximately
one (1) minute after removing the power supply.

Fitting the AoVest
Unbuckle the chest buckles on the AoVest and
set the buckles to maximum size.
Put on the AoVest and fasten all 3 buckles. Firmly
pull the buckle straps so that the vest ts snugly on
the body, but does not restrict a deep, full breath.
After adjusting, the sides of the AoVest should have
less than a 5 inch (12.7 cm) gap. They may overlap up
to 1 inch (2.5 cm).
Adjust the shoulder snaps to place the front upper
AoVest motors on the upper chest just below the
collar bone.
Step 3: Disconnecting and Reconnecting
the Battery
The AoVest battery comes connected inside of the
battery pouch. The battery should not require
disconnection or removal from the AoVest during
normal use. The serial number tag is included inside the
battery pouch.
Battery connected
To disconnect the battery from the AoVest, simply
unplug the battery plug from the vest.
Battery disconnected
The battery can now be removed from the AoVest.
When re-connecting the AoVest battery, the controller
should beep briey when the battery is connected.
Keep the AoVest battery pouch closed to protect the
battery and wires from potential damage.
Your AoVest is now ready for use!
IMPORTANT
Unplug the power supply from outlet when not in use.
If the battery has not been used for more than 30 days,
please recharge prior to using.

Recommended distance:
d = 1.2 m P
d=1.2 m P for 80 MHz to 800 MHz d=2.3 m P for 800 MHz to 2.5 GHz
Where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer and d is the
recommended distance in meters (m). The eld strength of xed RF
transmitters, as determined by an electromagnetic site survey(a)
should be less than the compliance level in each frequency
range(b). Interference may occur in the vicinity of equipment
marked with the following symbol.
Radiated RF interference
as per IEC 61000-4-3
3 V/m 80MHz
to 2.5 GHz
3 V/m
NOTE 1: The higher frequency range applies at 80 MHz and 800 MHz.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is aected by absorption and reection from structures, objects and persons.
(a) The eld strength from xed transmitters, such as base stations for radio telephones and mobile terrestrial radio equipment, amateur radio stations, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment in terms of xed RF transmitters, an electromag-
netic site survey should be considered. If the measured eld strength in the location in which the AoVest is used exceeds the applicable compliance level specied above,
the AoVest should be observed to verify normal operation. If abnormal performance features are observed, additional measures may be necessary, such as re-orienting
or relocating the AoVest.
(b) The eld strength should be less than 3 V/m over the frequency range from 150 kHz to 80 MHz.
