GENERAL REMARKS
General remarks on blood pressure and blood pressure measurement
1. To defl ate the cuff quickly, press the “START/STOP” switch.
2. The attached cuff is suitable for wrist circumferences of 13.5-
21.5 cm.
3. When attaching the cuff, the body of a blood pressure monitor should be placed on the inside of your wrist.
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 be taken regularly at the same time each day.
8. DO NOT place too much emphasis on the results of one measurement. Keep a continuing record of your blood pressure variations. A complete picture can only be obtained 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 fi ve 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 of sleep or constipation, or have just taken some exercise or eaten a meal.
3. Wrap the cuff around your wrist snugly. (
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

English
GENERAL REMARKS
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 or after smoking.
8. Measure your blood pressure when you are relaxed and still. Keep
English
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 when the cuff has been on your wrist for a few minutes or more. During this time, your wrist will have built up a higher blood pressure and you will not get valid reading.

Defi nitions and Classifi cations 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 signifi cance than data from just one measurement. For this reason, you must measure your blood pressure on a daily basis. Ideally, you should measure your blood pressure at the same time each day, wherever possible.

ABOUT “BLOOD PRESSURE”
What is blood pressure?
The heart is a pump that circulates blood throughout your body. Blood is pumped from the heart 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 blood, and the diastolic pressure that occurs when blood returns to the heart.
(Systolic) (Diastolic)
Left atrium
Artery
Left atrium
Artery
English
Left ventricle
Your blood pressure changes all the time.
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 a healthy person generally varies within a day.
The artery wall expands.

BLOOD PRESSURE Q&A
Q Why is the blood pressure measured at home different from that
measured by the physician or at a hospital?
A Your blood pressure may vary due to exercise, the ambient temperature
English
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 automatic nerve function. Blood
pressure differs with every heart beat. We are likely to think that our blood pressure is constant, but it varies if you take measurements in repetition. Blood pressure is susceptible to the time of day, such as morning 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 bene t of measuring my blood pressure at home? A Blood pressure measurements taken at home give reliable data as they
can be taken 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 blood pressure.
Always consult your physician for an interpretation of your blood pressure readings and to determine the proper treatment.
