SAFETY PRECAUTIONS

Warning

• Self-diagnosis of your physical condition based on the measurement
results of the Base Unit is extremely dangerous. Make sure you
always consult your physician concerning your physical condition.

• Do not use a mobile phone or other device that emits radio waves in
the vicinity of the Base Unit while taking blood pressure readings. Do
not take blood pressure readings in the vicinity of a TV, microwave
oven, etc. Doing so can produce incorrect readings.

• Never use the Base Unit for any other purpose other than taking blood
pressure readings.

• Do not use the Base Unit to measure the blood pressure of young
children.

• Never try to take the Base Unit or cuff apart, and never modify them in
any way. Doing so can lead to malfunction of the Base Unit and other
serious problems.

Batteries

Incorrect use of batteries can cause corrosive fluid to leak from them,
and creates the risk of fire and personal injury due to exploding batteries.
To avoid such problems, make sure you carefully observe the following
battery guidelines.

• Always make sure that the (+)/(–) polarity of batteries is correct when
you load them.

• Never mix new batteries with old ones.

• Never mix batteries of different types.

• Be sure to remove the batteries from the Base Unit if you do not plan

to use it for a long time.

• Use only the batteries that are specifically recommended for the Base
Unit.

• Take care when using your fingernail to remove batteries from the
battery compartment. Pulling on batteries can cause long nails to
break.

KEEPING ATTUNED TO YOUR BLOOD

PRESSURE LEVELS

Your blood pressure is like a constant message from your body.
Monitoring your blood pressure provides you with vital feedback about
your current physical condition. High blood pressure, for example, often
shows no symptoms of its own, and so except for an abnormally high
measurement reading. Left undetected and untreated, high blood
pressure can often lead to more serious, life-threatening illness.
All of this means that daily blood pressure readings for the purpose of
detecting early warning signs from our bodies are an essential part of
any comprehensive personal health management program.

The CASIO Blood Pressure Monitor Watch and Base Unit make it
possible for you to take quick and easy blood pressure readings at
home and while you are out. Together, they provide you with
essential blood pressure data throughout the day.

At home While you are out

Base Unit

Base Unit

The Base Unit is a cuff type digital blood pressure monitor that measures
your systolic and diastolic blood pressure, as well as your pulse rate. It is
also used for setting basic data on the Watch.

Watch

This Watch measures blood pressure using a fingertip pulse wave
detection system. After you use the Base Unit to measure your basic
data and send it to the Watch, you can use the Watch to take readings,
without applying pressure to your upper arm. Simply place your finger
onto the Watch’s sensor and your blood pressure and pulse rate appear
in a few moments.

The Story of Blood Pressure

What is Blood Pressure?

Blood pressure represents the change in pressure against the interior of
artery walls, which is caused by blood being sent through the circulatory
system by each beat of the heart. There are actually two blood pressure
values: systolic blood pressure and diastolic blood pressure.
Systolic blood pressure is the pressure exerted by the blood when the
heart contracts, causing artery walls to expand.
Diastolic blood pressure, on the other hand, is the pressure exerted by
the blood when the heart expands, and artery walls return to their
original shapes.

What causes blood pressure to change?

A variety of different factors can cause a change in blood pressure,
including age, climate, emotional stress, gender, living environment, and
basic diet.

• Average systolic blood pressure tends to rise with age due to natural
loss of elasticity in arterial walls.

Handling

• Do not use the Base Unit if it appears to be malfunctioning, damaged,
etc.

BP-1MY-2

• Your blood pressure fluctuates throughout the day. Normally, it is at its
highest shortly after you awake in the morning, and it reaches its
lowest level some time while you are asleep. A fluctuation between
maximum and minimum systolic blood pressure levels of about
20mmHg is considered normal.

The above is upper arm blood pressure data.

• A rise in blood pressure can be caused by physical exercise, drinking
coffee or tea, smoking, the need to urinate, and other factors.

• Blood pressure is also affected by your physical condition, as well as
stress due to your emotional state, worry, etc.

• A blood pressure reading can also be affected by your posture when
the reading is taken. Normally, your blood pressure will be lower if you
are sitting instead of standing.

• Temperature and humidity can also affect blood pressure. Normally,
winter blood pressure readings tend to be higher than summer
readings.

Definitions and Classification of Blood Pressure Levels

Though the general rule of thumb for normal systolic (maximum value)
blood pressure is your current age plus 90mmHg, this is not always
necessarily true. The following chart shows some general guidelines for
blood pressure values.

• The following tables show classifications for hypertension (high blood
pressure) according to the World Health Organization (WHO) and the
International Society on Hypertension (ISH) (1999).

• When diastolic blood pressure is up to 90mmHg, systolic blood
pressure greater than 140mmHg is classified as Isolated Systolic
Hypertension, while systolic blood pressure within the range of 140 to
149mmHg is classified as Subgroup: Borderline Isolated Systolic
Hypertension.

Why is high blood pressure a cause for concern?

As its name implies, high blood pressure causes arteries to be exposed
to high pressure, and can cause lesions in the arteries that supply blood
to brain, heart, liver, and other vital organs. Left untreated, high blood
pressure can lead to loss of heart function, hardening of the arteries, and
a host of other problems like those described below.

• Aneurysms in the brain’s blood vessels, which can lead to stroke

• Enlargement of the heart, which can lead to heart failure

• Narrowing of blood vessels in the kidney, which can lead to kidney

failure

• Premature hardening of the arteries throughout the body, especially
those in the heart, brain, and kidneys, which can lead to heart attack,
stroke, or kidney failure

What does low blood pressure indicate?

Some symptoms of low blood pressure are chronic fatigue, dizziness,
shoulder stiffness, palpitation of the heart, and shortness of breath. Be
sure to contact your physician if you suffer from any of these symptoms.

Monitoring Blood Pressure Levels on Your Own

When is the best time to take readings?

You should take readings during which you are most relaxed and stable.
It is also important to take readings at the same times everyday, every
morning, noon, and night, for example. Of course, you can also take
readings at any other time you wish, but the important thing is to take
blood pressure readings an integral part of your overall health control
activities.

Be sure to keep records.

Your blood pressure will fluctuate with changes in your physical
condition and even the weather. Because of this, you should keep a
record that includes not only measured values, but also information
about your physical condition and surrounding conditions. Try making it
your goal to build an entire year of daily records.

• You can make copies of the “Blood Pressure Record” at the back of
this manual and use them to keep track of changes in your blood
pressure and pulse measurements.

Is there anything I should do before taking a reading?

First of all, try to relax. Take five or six deep, cleansing breaths. Also,
note the following pointers.

Take readings in a quiet location.

Select a comfortable location that is free of loud noise and vibration, and
is neither overly hot nor cold. A temperature of about 20°C is best.

Take readings while you are calm.

Avoid times when you are worried or otherwise emotionally upset, and
after eating, exercise, or drinking coffee.

Maintain good posture during readings.

Keep your arm and wrist at about the same height as your heart. It is
also important to be free if tension.

Take readings at the same time everyday.

Remember that blood pressure is constantly changing. Try to take your
readings at the same time each day.

BP-1MY-3

Why are values produced by readings I take at home
different from values produced when my doctor takes
readings?

Slight tension caused by a visit to the doctor or a hospital can cause
blood pressure readings taken there to be a bit higher. This, of course,
assumes that you are following the correct procedures when taking your
readings at home.

It could be due to a condition called “white-coat hypertension.”

“White-coat hypertension” is a condition caused by the atmosphere that
is present in a hospital. It is an emotional condition, and does not
indicate a physical problem. It is important to be relaxed while taking a
blood pressure reading.

Controlling Blood Pressure

Daily Life

How you live your daily life is an important factor in achieving good blood
pressure. Improved living habits and patterns can actually decrease the
chance of high blood pressure. The first step on the road to proper living
is eliminating overexertion and stress.
The following are some proven tips for developing good living habits and
enjoying the benefits of good blood pressure.

• Reduce salt intake.

• Go to bed early and get up early.

• Eat regular meals every morning, noon, and night.

• Get enough sleep.

• Set aside enough time for yourself in order to get some stress relief.

• Try to achieve a balance between your mental and physical well

being.

Exercise

Proper exercise plays an important role in controlling blood pressure.
The accent here is on the word “proper,” because the wrong type of
exercise can actually do more harm than good. Aerobic exercise, such
as walking at a comfortable pace, is the best for controlling blood
pressure.

Healthy Walking Tips

Keep your gaze on the ground
relatively far in front of you.

Keep your chin in.

Keep your head upright and
pointed straight ahead.

Keep your chest out
and your back straight.
