1. To deﬂate the cuff quickly, press the “START/STOP” switch.
2. The attached cuff is suitable for arm circumferences of 20-32 cm.
3. When attaching the cuff, the air hose should be placed on the inside of your arm on topof the artery.
4. Self measurement is not therapy! In no event should you change the dosage of your
medication prescribed by your physician.
5. As preparation for measuring your blood pressure, 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. Your blood pressure varies constantly throughout the day. Measurements should betaken regularly at the same time each day.
8. DO NOT place too much emphasis on the results of one measurement. Keep acontinuing record of your blood pressure variations. A complete picture can only beobtained from a large number of readings.
9. Emotional stress tends to cause your blood pressure to rise.

To obtain correct blood pressure measurements
1. Take ﬁve or six deep breaths and then relax before measuring your blood pressure. If you
are tense when taking the measurement, you will not get a valid reading.
2. Your blood pressure will be elevated if you are anxious or irritated, suffering from lack ofsleep or constipation, or have just taken some exercise or eaten a meal.
3. Wrap the cuff around your arm and tighten it so that one ﬁnger can be inserted between
the cuff and arm. (See page 18)
4. DO NOT measure your blood pressure after bathing or drinking.
5. If you feel the need to urinate, do so before measuring your blood pressure.
6. Measure your blood pressure where the room temperature is around 20°C. DO NOT
measure your blood pressure when it is too cold (below 10°C) or too hot (above 40°C) in
the room.
7. DO NOT try to measure your blood pressure immediately after drinking coffee or tea orafter smoking.
8. Measure your blood pressure when you are relaxed and still. Keep the center of the cuff
at the level of your heart and DO NOT move your arm or talk.

- Eng 3 -EnglishGeneral remarks on blood pressure and blood pressure measurement

GENERAL REMARKS

English9. DO NOT measure blood pressure when the cuff has been on your arm for a few minutes
or more. During this time, your arm will have built up a higher blood pressure and you will
not get valid reading.
10. The ﬁgure below shows the blood pressure classiﬁcations under the WHO standards.

Remarks:
The graph is not exact, but may be
used as a guide in understanding
non-invasive blood pressure
measurements. The device is only
intended for use with adults.

Deﬁnitions and Classiﬁcations of Blood Pressure Levels

Measure your blood pressure at the same time each day.
* Your blood pressure changes all the time. This means that data gathered over a long
period has far more signiﬁcance than data from just one measurement. For this reason,
you must measure your blood pressure on a daily basis. Ideally, you should measure yourblood pressure at the same time each day wherever possible.

PRECAUTIONS FOR USE AND MAINTENANCE
1. If you suffer from heart disease, high blood pressure or other circulatory disease, consult
your physician before using the monitor.
2. If the cuff pressure feels abnormal or you experience any other irregularity while using thecuff, reduce the pressure immediately by pressing the “START/STOP” switch and thenconsult the sales outlet where you purchased the monitor.
3. If you think the measurement is abnormal or if measurement makes you feel unwell,
discontinue use and consult your physician.
4. Blood pressure measurement may not be possible for anyone with a weak pulse or
arrhythmia.
5. Repeated blood pressure measurement may cause problems such as congestion or
swelling in some people.
6. Frequently repeated blood pressure measurements will not give accurate results. Allow
an interval of about 10 minutes between measurements.
7. If you suffer from a severe problem with blood circulation in your arms, consult yourphysician before using the monitor. Failure to do so could be hazardous to your health.
8. Measurement may not be possible for anyone with insufﬁcient blood ﬂow to the area
where measurements will be taken or who suffers from a frequent irregular heartbeat.
Consult your physician for advice on whether to use the monitor.
9. DO NOT wrap the cuff around an injured arm.
10. DO NOT wrap the cuff around an arm in which a drip (intravenous infusion) is inserted or
which is being used for blood transfusion as part of medical treatment. Doing so could
result in an injury or a serious accident.
11. DO NOT use the monitor in the vicinity of ﬂammable gases such as those used foranaesthesia. Doing so could ignite the gases and cause an explosion.
12. DO NOT use the monitor in enriched oxygen environments such as a hospital’s
hyperbaric chamber or oxygen tent. Doing so could ignite the oxygen and cause a ﬁre.
13. DO NOT use mobile phones near the monitor as this could result in a malfunction.
14. If you use a cardiac pacemaker, consult your physician before using the monitor.

measuring your blood pressures.
• When the unit detects your pulse, the mark ﬂashes
on and off, then the unit gives your blood pressure valueon the lower section of the display.

• Upon completion of measurement, the buzzer sounds
and the unit automatically exhausts air from the cuff.
Then, the Systolic blood pressure/Diastolic bloodpressure/pulse will appear on display.
• As long as the unit functions correctly, the bloodpressure and the pulse rate for the result with the recordof the time and date are automatically stored in memory
as one set of data.
• Up to 60 sets of measurement data can be stored
in the memory. If you measure your blood pressure
when 60 sets of measurements have already been
stored in memory, the earliest set of measurements
is automatically deleted to make way for the newmeasurements.

ABOUT “BLOOD PRESSURE”
The heart is a pump that circulates blood throughout your body. Blood is pumped from theheart at a constant pressure into arteries. This pressure is called the arterial blood pressure
and represents, in general terms, your blood pressure. Blood pressure is indicated by several
kinds of pressures, including the systolic pressure that occurs when the heart pumps bloodand the diastolic pressure that occurs when blood returns to the heart.

(Systolic)(Diastolic)ArteryArteryLeft atrium

Left atrium

Left
ventricle

Leftventricle The artery wall expands.
Contraction

Normal state is restored
to the artery wall.
DilationYour blood pressure changes all the time.

Blood pressure value (mmHg)

Your blood pressure differs according to your age, gender and a range of other factors. It is
likely to be affected by your biorhythm during the day and by your posture, physical activities,
mental activities, level of stress and even by the air temperature. The blood pressure of ahealthy person generally varies within a day.

Diastolic blood pressure

Time of day- Eng 27 -EnglishWhat is blood pressure?

BLOOD PRESSURE Q&A
Q Why is the blood pressure measured at home different from that measured by thephysician or at a hospital?
EnglishA Your blood pressure may vary due to exercise, the ambient temperature or your mental
state. When you have a physician or nurse measure your blood pressure, the pressure
value is likely to be 10 to 20 mmHg higher than usual due to anxiety and/or stress.
Knowing what affects your blood pressure helps you to better monitor your health.

Q Why does the blood pressure obtained vary with measurement?
A Our blood pressure is adjusted by the function of automatic nerve. Blood pressure differswith every heart beat. We are likely to think that our blood pressure is constant, but itvaries if you take measurements in repetition. Blood pressure is susceptible to the time ofday, such as forenoon and afternoon, season and atmospheric temperature. In addition,
blood pressure is easily affected by mental stress or emotional ups and downs. It tends
to increase when you feel tension or decrease when you are relaxed.

Q What is the beneﬁt of measuring my blood pressure at home?
A Blood pressure measurements taken at home give reliable data as they can betaken when you are in a stable and relaxed condition. Physicians place considerable
importance on blood pressure measurements taken at home. You should measure
your blood pressure at the same time each day and record the variations in your bloodpressure.

Always consult your physician for an interpretation of your bloodpressure readings and to determine the proper treatment.
