You must install 4 type AA (1.5 volt) batteries (included), or use the optional
AC Adapter (see page E-14 for using the Monitor with AC Adapter) and
attach the cuff to the monitor before using it. To install batteries (or replace
them if the “Low Battery” symbol appears on display), proceed as follows:
1. Remove battery compartment cover by gently pushing down on arrow and
sliding cover forward.
2. Put in bottom row of batteries first. Place the
batteries in compartment with positive (+) and
negative (–) terminals matching those indicated in
the compartment. Be sure batteries make contact
with compartment terminals.
3. Replace cover by sliding it into the compartment and
gently pressing into place.
NOTE: Rechargeable batteries will not work with this monitor.
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.

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.

INDEX
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.

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.
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.
TAKING YOUR BLOOD PRESSURE
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.
2. Lay left arm on the table, palm up and thread cuff
end through metal loop, smooth size against arm.
Then position the tube off-center toward the inner
side of arm in line with the little finger.
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 90 readings in memory).
NOTE: If you press the MEMORY button before the auto shut-off, the current
measurement will not be stored into memory.
7. Remove cuff and make note of your blood pressure and pulse rate in the
Blood Pressure Logbook, indicating the date and time of measurement.
IMPORTANT: Measure blood pressure at the same time each day.

WHAT IS AN IRREGULAR HEARTBEAT
ABOUT CUFF INFLATION METER
The UA-851 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 occured 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.
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.

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. Taking your blood pressure repeatedly without waiting an
interval of 5 minutes between readings, or without raising your arm to allow
blood to flow back to the heart, can also affect it.
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.

Assessing High Blood Pressure for Adults
The following standards for assessing high blood pressure (without regard to age
or gender) have been established as a guideline. Please note that other risk factors
(e.g. diabetes, obesity, smoking, etc.) need to be taken into consideration and
may affect these figures. Consult with your physician for an accurate assessment.

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.
• Record your measurement in the logbook.

E-17
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
based on things 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. Please see the back of the manual for the blood pressure tracking
log.
