Using the correct cuff size is important for an accurate reading. A cuff that is too large will
produce a reading that is lower than the correct blood pressure; a cuff that is too small will
produce a reading that is higher than the correct blood pressure. With your arm hanging
at the side of your body, measure the circumference of your upper arm at the midpoint
between the shoulder and elbow.

Cuff Size Indicator On The Cuff
Our cuff has an indicator which tells you whether you are using the correct cuff size or
not. Place the cuff on your arm (see Page E-6 to learn how to put the cuff on correctly)
and if the Index Mark points within the Proper Fit Range, you are using the
correct cuff size. If the Index points outside of the Proper Fit Range, contact A&D
Medical at 1-888-726-9966 (in Canada, call Auto Control Medical at 1-800-461-
0991) for more information on where to obtain a cuff replacement.
NOTE: If the cuff size indicator falls on a borderline between two size categories,
pick either one and make sure to use the same cuff size for each measurement.

Tips for Blood Pressure Monitoring:
☞
Relax for about 5 minutes before measurement.
☞
Do not smoke or ingest caffeine at least 30 minutes prior to measurement.
☞
Remove constricting clothing and place cuff on bare arm.
☞
Unless your physician recommends otherwise, use left arm
to measure pressure.
☞
Do not talk during measurement.
☞
Do not cross legs and keep your feet flat on floor during measurement.
Now you are ready. Follow these simple steps:
1. Sit comfortably with your left arm resting on a flat
surface so that the center of your upper arm is at the
same height as your heart.
After installing the batteries, you
must attach the blood pressure cuff to
the monitor. To do so, insert the Air
Connector Plug of the blood pressure
cuff into the Air Socket of the monitor
firmly.
NOTE: Be sure to differentiate the
Air Socket from the AC Adapter Jack.
The Air Connector Plug will only
securely fit into the correct jack.

3. Secure cuff around arm. The cuff should be snug but
not too tight. You should be able to insert two fingers
between the cuff and your arm.
2. Lay left arm on the table, palm up and thread cuff end
through metal loop, smooth side against arm. Then
position the tube off-center toward the inner side of arm
in line with your little finger.
TAKING YOUR BLOOD PRESSURE
4. Confirm that the Index Mark points within the
proper fit range.
5. Press the START button. As the cuff pressurizes,
measurement will begin and the Cuff Inflation Meter will show on the display
screen. It is normal for the cuff to feel very tight.
Note: If an appropriate pressure is not obtained, the device automatically starts
to inflate again.
Note: If you wish to stop inflation at any time, press the START button again.
6. When the measurement is complete, the systolic and diastolic pressure readings
and pulse rate are displayed. The cuff deflates and the monitor automatically shuts
off after 60 seconds, or you can turn it off by pressing the START button. Your
measurement is automatically stored in memory (the monitor can store up to 51
readings in memory).
7. The monitor automatically transmits your readings wirelessly if it is within range
of an active ActiLink USB Transceiver. If the monitor is not in range, the data will
be stored in memory until the blood pressure monitor is activated in range of an
active ActiLink.
IMPORTANT: Measure blood pressure at the same time each day.
IMPORTANT: The ActiLink USB Transceiver will not work when plugged into a
computer in sleep, suspend, or hibernation mode.
IMPORTANT: The range of the UA-851THW may be affected by walls, materials
around or between the UA-851THW and ActiLink, and other environmental factors.

WHAT IS AN IRREGULAR HEARTBEAT?
ABOUT CUFF INFLATION METER
The Cuff Inflation Meter is located on the left side of the display screen to tell you
when the blood pressure monitor is inflating and deflating the cuff. The Cuff Inflation
Meter moves up during inflation and moves down during deflation.
Inflation in Progress Inflation Complete Deflation/Measurement in
Progress
LifeSource ® blood pressure monitors are easy to use, accurate and digitally display full
measurement readouts. Our technology is based on the “oscillometric method” – a
noninvasive blood pressure determination. The term “oscillation” refers to any measure
of vibrations caused by the arterial pulse. Our monitor examines the pulsatile pressure
generated by the arterial wall as it expands and contracts against the cuff with each
heartbeat.
The cuff is inflated until the artery is fully blocked. The inflation speed is maximized
and the pressure level is optimized by the device. The monitor takes measurements
while the cuff is both inflating and deflating. This results in a faster measurement
providing greater comfort to the user.

WHAT IS AN IRREGULAR HEARTBEAT?
The UA-851THW Blood Pressure Monitor provides a blood pressure and pulse rate
measurement even when an irregular heartbeat occurs. The Irregular Heartbeat symbol
will appear in the display window in the event an Irregular Heartbeat has
occurred during measurement. An irregular heartbeat is defined as a heartbeat that
varies by 25% from the average of all heartbeat intervals during the blood pressure
measurement. It is important that you relax, remain still and refrain from talking
during measurements.
NOTE: We recommend contacting your physician if you see this
symbol frequently.

What Is Blood Pressure?
Blood pressure is the force exerted by blood against the walls of the arteries. Systolic
pressure occurs when the heart contracts; diastolic pressure occurs when the heart
expands. Blood pressure is measured in millimeters of mercury (mmHg).
What Affects Blood Pressure?
Blood pressure is affected by many factors: age, weight, time of day, activity level,
climate, altitude and season. Certain activities can significantly alter one’s blood
pressure. Walking can raise systolic pressure by 12 mmHg and diastolic pressure by 5.5
mmHg. Sleeping can decrease systolic blood pressure by as much as 10 mmHg.
In addition to these factors, beverages containing caffeine or alcohol, certain
medications, emotional stress and even tight-fitting clothes can make a difference in
the readings.
What Causes Variations In Blood Pressure?
An individual’s blood pressure varies greatly from day to day and season to season.
For hypersensitive individuals, these variations are even more pronounced. Normally,
blood pressure rises during work or play and falls to its lowest levels during sleep.

What Is Hypertension?
Hypertension (high blood pressure) is the diagnosis given when readings consistently
rise above normal. It is well known that hypertension can lead to stroke, heart attack
or other illness if left untreated. Referred to as a “silent killer” because it does not
always produce symptoms that alert you to the problem, hypertension is treatable
when diagnosed early.
Can Hypertension Be Controlled?
In many individuals, hypertension can be controlled by altering lifestyle and
minimizing stress, and by appropriate medication prescribed and monitored by
your doctor. The American Heart Association recommends the following lifestyle
suggestions to prevent or control hypertension:
Don’t smoke Have regular physical checkups
Reduce salt and fat intake Maintain proper weight
Monitor your blood Exercise routinely
pressure at periodic intervals
Why Measure Blood Pressure at Home?
It is now well known that, for many individuals, blood pressure readings taken in a
doctor’s office or hospital setting might be elevated as a result of apprehension and
anxiety. This response is commonly called “white coat hypertension.” In any case,
self-measurement at home supplements your doctor’s readings and provides a more
accurate, complete blood pressure history. In addition, clinical studies have shown that
the detection and treatment of hypertension is improved when patients both consult
their physicians and monitor their own blood pressure at home.

ABOUT BLOOD PRESSURE
Answers to Why Your Readings Are Different Between Home and
at the Doctor’s Office
Why are my readings different between home and at a doctor’s office?
Your blood pressure readings taken in a doctor’s office or hospital setting may be
elevated as a result of apprehension and anxiety. This response is known as white coat
hypertension.
When I bring my monitor to a doctor’s office, why do I get a different
measurement from my monitor to that taken by a doctor or nurse?
The healthcare professional may be using a different sized cuff. The size of the bladder
inside the cuff is critical for the accuracy of the measurement. This may give you a different
reading. A cuff too large will produce a reading that is lower than the correct blood pressure;
a cuff that is too small will produce a reading that is higher than the correct blood pressure.
There may also be other factors that can cause the difference in measurements.
Keys to Successful Monitoring:
Blood pressure fluctuates throughout the day. We recommend that you are consistent
in your daily measurement routine:
• Measure at the same time every day.
• Sit in the same chair/position.
• Do not cross legs and keep your feet flat on the floor.
• Relax for 5 minutes before measurement.
• Use the correct cuff size to get an accurate reading.
• Sit still during measurement – no talking, eating or sudden
movements.

E-16 LifeSource Health Line (Toll-Free): 1-888-726-9966
Establishing Baseline Measurements
The most important method to get an accurate blood pressure measurement is
consistency. To get the most benefit out of your monitor, it is important to establish a
“baseline measurement.” This helps build a foundation of measurements that you can
use to compare against future readings. To build this baseline measurement, devote
two weeks for consistent blood pressure monitoring. This involves doing everything
the same way when you measure (e.g. measuring during the same time of day, in the
same location, sitting in the same chair, using the same cuff, etc.). Once you establish
your baseline measurement, you can start evaluating if your measurement has been
affected by factors such as lifestyle changes or medication treatment.
How Do I Record My Blood Pressure?
Blood pressure readings are typically recorded with the systolic pressure written first,
followed by a slash mark and the diastolic pressure. For example, 120 mmHg systolic
and 80 mmHg diastolic measurements are written as 120/80. Pulse is simply written
with the letter “P” followed by the pulse rate—P 72, for example.
Each measurement you take is automatically sent to your computer and charted
instantly. The Wellness Connected software will direct all of the measurements from
a device to the account the device is registered to. If the device is not registered,
measurements will not be off loaded. If you choose, you may sign up for an
ActiHealth internet account and send your measurement data there. Data sent to
ActiHealth will not be available on your Wellness Connected account.
