GENERAL REMARKS

General remarks on blood pressure an d blood p re ss ur e
measurement

1. If the cuff is to be deflated quickly, depress “POWER” switch.

2. The attached cuff is suited for a wrist circumstance of 13.5 cm to 19.5
cm.

3. When attaching the cuff, the body of a blood pressure monitor should be
placed on the inside of your wrist.

4. Sel f measuremen t is not therapy! In no case may you change the
dosage of medication prescribed by your physician.

5. In preparation for blood pressure measurement, you should urinate and
then remain relatively still for 10 to 15 minutes prior to measurement.

6. Exercising, eating, drinking, smoking, etc., prior to measurement may
affect the results.

7. Blood pressure varies constantly throughout the day. Measurement
should be made regularly at the same time each day.

8. DO NOT be too impressed by the results of one measurement. Keep a
record of blood pressure variations. Many reading tell a story.

9. Emotional stress may tend to cause blood pressure to rise.

For proper measure of blood pressure

1. Take a deep breath five or six times and then relax before measuring
your blood pressure. If you are tense when taking the measurement, you
will not get a valid reading.

2. Blood pressure will be elevated when you are in a worrisome or irritated
state, suffering from lack of sleep or constipation, or after exercise or a
meal.

3. Wrap the cuff around your wrist snugly. (See page 14)

4. DO NOT measure blood pressure after bathing or drinking.

5. When you feel like relieving yourself, you should do so before measuring
your blood pressure.

6. Measure your blood pressure where the room temperature is about
20°C. DO NOT measure blood pressure when it is too cold (below 10°C)
or too hot (above 40°C) in the room.

- Eng 2 -

GENERAL REMARKS

7. DO NOT try to measure blood pressure immediately after drinking
coffee or tea or smoking.

8. Measure blood pressure with a relaxed and quiet posture. Keep
the center of the cuff at the level of your heart, and DO NOT move
your arm or talk.

9. DO NOT measure blood pressure after the cuff has been on your
wrist for a few minute, as you arm will have built up higher blood
pressure, and you will not get valid reading.

10. Next figure shows the classification of blood pressure according
to WHO-standard.

Remarks:

The graph is not exact,
but may be used as a
guide in understanding
non-invasive blood
pressure measurements.
The device intended for
use in adult population.

Definition and Classification of Blood Pressure Levels

Measure your blood pressure at the same time on a daily basis.
* The blood pressure changes at all times. This means that data

gathered over a long period has great significance instead of data
on just one measurement. It is therefore necessary to measure
your blood pressure on a daily basis. Ideally, you should measure
your blood pressure daily at the same time.

POINTS FOR ACCURATE MEASUREMENT

Blood pressure varies with posture, the time of day and numerous
other factors. It is recommended that you measure your blood
pressure at the same time each day in the same posture.

Take a deep breath and
then relax before
measuring blood pressure.

Lightly open your hand
on the table with palm up
and relax your fingers.

Fold up a towel and put it
between your elbow and wrist
to steady your forearm.

Make sure that your posture is correct.
Remain still during measurement.
Wrap the wrist cuff properly.

Make sure that your
posture is correct.

Level the blood pressure
monitor to your heart.

DO NOT clench your
fist tightly.

DO NOT place the
monitor on the outside
of your wrist.

ABOUT “BLOOD PRESSURE”

English

What is blood pressure?

The heart is a pump that circulates
blood throughout your body. Blood is p umpe d from the heart into the
ar terie s. This pre ss ure is ca ll ed the arte ri al bloo d pr essur e, which
represents, in general, blood pressure. Blood pressure is indicated by
several kinds of pressures such as: systolic pressure that occurs when the
heart pumps blood; and diastolic pressure that occurs just when blood
returns to the heart.

(Systolic)

Artery

Left atrium

Left

The artery wall expands.

ventricle

Contraction

Blood pressure changes at all times.

(Diastolic)

Left atrium

Left
ventricle

Artery

Normal state is restored
to the artery wall.

Dilation

Blood pressure differs
with age, gender and other factors. Blood pressure of one person is likely to
be aff ected by biorhythm of a day, posture, physical activities, ment al
activities, stress and atmospheric temperatures.
It is said that blood pressure of a healthy person varies by 20 to 50 mmHg
within a day.

QUESTIONS AND ANSWERS ON BLOOD PRESSURE

QQQ Why is the blood pressure measured at home different from that

measured at the doctors or a hospital?

A When you have a doctor or nurse measure your blood pressure,

the pressure value is likely to be 10 to 20 mmHg higher than
usual because of concern and nervousness. To know what
affects blood pressure is crucial to your health monitoring.

QQQ What is the benefit of measuring blood

pressure at Home?

A Blood pressure measured at home is

reliable since it can be measured in a
stable and relaxed condition. Doctors
la y i mpo rtanc e o n b lood pre ssu re
measurements taken at home . It is
recommended to measure your blood
pressure at the same time on a daily
basis and to record blood pressure variation.

Always consult your physician for interpretation of your blood
pressure readings and proper treatment.
* Improper interpretation of measurement results may worsen

Caution

your symptoms. Some individuals with hypertension, diabetes,
kidne y disor ders, arteriosc leros is or perip heral vasc ular
disease may see a significant difference in blood pressure
readings taken from the wrist as compared to readings from
the upper arm.

BEFORE ASKING FOR REPAIR/INSPECTION

Be sure to check the following before sending your blood pressure
monitor for repair/inspection.

Display gives no
indication even
when you press
Power switch.

No measurement is
possible.

If your blood pressure readings are abnormally
higher or lower than those taken in hospital:

If your blood pressure readings are abnormally
high or low:

Point to be checked

Check whether batteries
are dead.

Check whether batteries
are installed with incorrect
polarity ( + – ).

Check if the mark has come
on.

Check if the wrist cuff is
wrapped properly.

Did you stay calm during
measurement?

Note that measurement of blood pressure may not be possible
for someone with an extremely weak pulse or cardiac arrhythmia
(irregular pulses).

See page 26.

See pages 13 and 16.

How to repair

Replace all batteries with new
ones.

Load the batteries with correct
