INTRODUCTION
Thank you for selecting the Oregon ScientificTM
BLE Upper Arm Blood Pressure Monitor
(BPU321). The BPU321 features multi-language
voice announcement and playback of blood
pressure measurements for added convenience
and has been designed to provide you with many
years of reliable service. The monitor can help
you measure and track the following metrics:
Systolic pressure
Diastolic pressure
Average morning / evening blood pressure
Heart rate
The monitor is able to store up to 100
measurements per user (maximum 2 users) and
equipped with the latest Bluetooth Smart
technology to achieve reliable transmission
linkage with a mobile device or tablet PC that is
with the logo and corresponding
application. From now on, you can easily track
your health on a daily basis.
Readings taken by the blood pressure monitor
are equivalent to those obtained by a trained
observer using the cuff and stethoscope
auscultation method. Clinical performance were
successfully done against ANSI/AAMI SP10 and
international protocol, and the B.H.S.(British
Hypertension Society) has rated this product
“recommended for clinical and home use”, the
highest grading available for blood pressure
monitors.
Please keep this manual handy as you
use your new product. It contains practical
step-by-step instructions, as well as technical
specifications and warnings you should know
about.

Contact your local waste disposal
authority for instructions on how to dispose of
used batteries. Used batteries can be harmful to
the environment, and should not be thrown out
with household trash.

POSITIONING THE ARM CUFF
Ensure the arm cuff is correctly placed to obtain
an accurate reading.
If your physician has diagnosed you with
poor circulation in your left arm, use your right
arm.
1. Choose the position from which you wish to
measure, sitting or lying down.
2. Roll or push up your sleeve to expose the
The air tube should run down, between the inside
of your forearm and the side of your chest, in line
with your middle finger.
5. Fasten the arm cuff so it fits snugly. If the cuff
is too loose, the measurement will not be
accurate.
PREPARING TO TAKE BLOOD PRESSURE
MEASUREMENT
You can choose to take blood pressure while
sitting or lying down. Below are some helpful tips
for taking a measurement.
Be sure to set the clock before taking your
first measurement, or whenever you replace
the batteries, so that the date and time are
stored in the memory with your history. For
instructions, refer to Monitor Settings
section.
It is important to relax when taking your blood

pressure. Try to take a 15-minute rest before
you begin.
Do not lean backward or bend your wrist
inward while taking a measurement.
Do not sit cross-legged and avoid talking or
moving your fingers and hand while taking a
measurement. Rapid movements or other
activities may alter your reading.
Wait at least an hour before taking your blood
pressure if you have just eaten a large meal.
Do not smoke or drink alcohol before taking
your blood pressure.
Do not measure your blood pressure if you
are under stress.
Remove all accessories from your arm.
Wait at least 3 minutes between
measurements. This allows your blood
circulation to recover.
For a meaningful comparison, try to measure
under similar conditions. For example, take daily
measurements at approximately the same time,
on the same arm, or as directed by a physician.
TAKING A MEASUREMENT
If you want the monitor to synchronize with the
application of your mobile device. Please do
preparation before starting a measurement.
1. Relax your arm.
Digits will appear on the screen.
5. Once the pressure reaches a certain level, it
will slowly deflate until the results are
displayed on the LCD.
NOTE To stop the measurement process at
any time, press .
6. The monitor automatically attempts to send
the record wirelessly to your mobile device.
If data transmission fails, Err 1 will appear
while a voice prompts.
7. To conserve battery life, monitor will turn off
1 minute after taking a measurement.
Alternatively, press to manually turn off
monitor.
UNDERSTANDING THE READING

Why measure your blood pressure?
Blood pressure measurement can highly reflect
one’s health condition. High blood pressure is
potentially linked to serious illnesses such as
stroke, heart disease and kidney failure. Since
there is no symptom most of the time, many
hypertensive people do not realize they are at risk
until their health is seriously threatened.
What is the standard blood pressure
classification?
The figure illustrates the blood pressure
classification made by World Health Organization
(WHO) and International Society of Hypertension
(ISH) in 1999.

dealer or designated collection point for proper
disposal.
USEFUL REFERENCE
ABOUT BLOOD PRESSURE
What is blood pressure?
Blood pressure is the force generated by the
blood against the walls of arteries during cardiac
contraction and relaxation (e.g., the pumping
action of the heart).
What are systolic pressure and diastolic
pressure?
When ventricles contract and pump blood out of
the heart, blood pressure reaches its maximum
value. This highest pressure in the cycle is known
as systolic pressure. When the heart relaxes
between heartbeats, the lowest blood pressure is
diastolic pressure.
Reference material: 1999 World Health
Organization - International Society of
Hypertension Guidelines for the management of
hypertension, Journal of Hypertension, 1999,
17(2): 151-183.
This is used as the basis for the coloured
hypertension indication bar to the right of the
screen.
Blood pressure is considered high when
either the diastolic or systolic blood pressure
value exceeds the normal range. When a

Only a physician can tell you your normal
blood pressure range and the point at which
you are at risk. Consult your physician to
obtain these values. If the measurements
taken with these products fall outside the
range, consult your physician.
Why does my blood pressure fluctuate
throughout the day?
Individual blood pressure varies greatly both on a
daily and a seasonal or temperature basis. These
variations may be more pronounced in
hypertensive patients. Normally the blood
pressure rises while at work and is at its lowest
Then it starts inflating the arm cuff to 180mmHg
or higher until it senses that it has blocked your
blood in the artery.
After that, the deflation process starts, during
which time the unit detects pressure oscillations
generated by beat-tobeat pulsatile, which is used
to determine the systolic, mean and diastolic
pressure, and also your pulse rate. Any motion
during this period will result in an incorrect
measurement.
After all readings are determined and displayed
on the LCD, the measurement is finished and the
arm cuff automatically deflates.

The graph below illustrates the variations over a
single day with measurement taken every 5
minutes. The thick line represents sleep time. The
rises in blood pressure at 4PM (A in the graph)
and 1 2AM (B in the graph) correspond to an
attack of pain and sexual intercourse (Beven,
Honour & Stott, Clin. Sci. 36:329, 1969).
HOW THE BLOOD PRESSURE MONITOR
WORKS
This product uses the Oscillometric Measuring
method to detect your blood pressure. Before
every measurement, the unit establishes a “zero
pressure” equivalent to the air pressure.
