INTRODUCTION
Thank you for purchasing wheezo®
Digital Wheeze Monitor by Respiri.
This manual provides important
information to help you use the
monitoring system properly. Before
using this product, please read the
Owner’s Manual thoroughly.
wheezo®accurately records breathing
sounds and detects and analyses
wheeze. Easy to use, the wheezo®
ecosystem of breath sensor, app
and cloud storage provides a service
to record and review your wheeze
rate results and history, including
symptoms and triggers and medication
schedule and usage, correlated with
environmental data such as weather,
pollen and air quality. Over time, by
eliminating guesswork and increasing
your awareness and knowledge of how
wheeze affects you, wheezo®may help
you and your doctor.
INTENDED USE
The wheezo®system is a smartphone-
based system that detects the presence
of wheeze and uses an algorithm
to provide a wheeze rate. wheezo®
is intended to monitor wheeze, an
abnormal breath sound and sign of
airflow limitation in the lungs. It is the
sound the doctor listens for with a
stethoscope when examining a patient.
wheezo®is intended to monitor wheeze
in adults and children over 2 years.
Adults should assist children under 14
years old.

WHEEZE RATE PRINCIPLE
Wheezing is an abnormal breath sound
which serves as physiological sign of
airflow limitation in the lungs. Wheeze
rate is the percentage of the recorded
breath sounds occupied by wheeze.
Monitoring and tracking wheeze rate
over time may help patients and their
health professional assess day to day
care.
LIMITATIONS OF USE AND
CONTRAINDICATIONS
wheezo®is a home monitoring device
not intended for diagnostic use. When
wheezo®is used to monitor wheeze,
the user should be under the care of a
licensed healthcare professional.
A licensed healthcare
professional’s advice is required
to understand the meaning and
importance of wheeze rate.
WARNINGS
• If the user is feeling breathless, or
experiencing other symptoms, it is
important to prioritise treatment over
taking a wheeze rate. Do not delay
treatment.
• Regardless of the wheeze rate,
if the user has signs and symptoms
such as, but not limited to, chest
tightness, shortness of breath,
coughing or wheezing, they should
always follow their healthcare
professional’s advice.

ACCESS TO BLUETOOTH®
Enable Bluetooth®on your smart device
in order to pair with wheezo®breath
sensor. You can enable Bluetooth®in
your smart device settings. Check your
smart device manual on how to do this.
BLUETOOTH®PROXIMITY
Make sure that wheezo®breath sensor
is within Bluetooth®proximity of your
smart device. If your smart device is too
far away from the breath sensor, the
connection could be lost.
OPERATING ENVIRONMENT
wheezo®has been designed for use in
a quiet environment e.g. home, school
or office. It is not designed to be used
in direct air currents (e.g. wind), source
of heat or cold, direct sun rays or other
source of light or energy, dust, sand
or any other chemical substances or
performance will be affected.

7WZO01-0004 | Owner’s Manual | Version 10 | En.
TAKING A WHEEZE RATE
1. wheezo®needs to be used in a quiet
place. No talking, TV or music and
limit movement.
2. wheezo®is designed to be applied
to the trachea (windpipe). Using the
finger grips on the sides as a guide,
firmly hold the breath sensor’s blue
diaphragm (applied part) to the side
of your trachea on the lower part of
the neck. Tap Start recording on the
app and breathe normally.
3. Keep breathing normally until the
app has completed the recording
and analysis of your breath sounds.
wheezo®needs between 30 – 60
seconds to analyse your breath
sounds for wheeze rate, depending
on the background noise and the
correct position of the sensor.
If you have a blocked nose, it is
recommended to open your mouth
while recording.
4. Your wheeze rate will be displayed.
Follow the instructions in the app to
set up an account so you can store
your history of recordings, wheeze
rate results and other information
securely on the cloud.
5. Turn the breath sensor off by holding
the power button until the LED goes
out. Note that it will automatically
turn off after 2 minutes of remaining
idle in order to save power.

DATA SYNCING
wheezo®is capable of operating offline. The app can store 20 of the most recent
wheeze rate results locally on the smart device and they will be uploaded to the
cloud when the app regains an active internet connection. When the app needs to
save a new wheeze rate and has already stored 20 results, the wheeze rates will be
overwritten by the new wheeze rate.
