Notes on Safety

Important instructions for obtaining meaningful readings

Avoid eating and drinking (alcohol), smoking, sport and taking medicines before measuring your blood pressure as this could affect your blood pressure level.

Before you start sit comfortably on a chair and relax. It is recommended to check your blood pressure at least twice a day, in the morning after getting up and in the evening after work, or as advised by your doctor.

Do not move and do not speak while the measurement is being taken. Avoid measuring your blood pressure while you are in a moving vehicle.

Allow an interval of at least three minutes between readings. Otherwise congestion of blood might occur and distort the readings. Always remove the cuff between readings.

Bare your wrist and take of your watch and jewellery before applying the cuff. Do not constrict the flow of your blood if you push up your sleeve.

Cautions

Blood pressure measurement is not suitable in case of serious arteriosclerosis (hardening of the arteries).

The pulse rate indicator is not suitable for monitoring the frequency of cardiac pacemakers.

If you suffer from disorders of heart rhythm, known as arrythmia, you should only use this blood pressure monitor in consultation with your doctor. In certain cases oscillometric measurement methods can produce incorrect readings.

Pregnant women should only measure their own blood pressure in consultation with their doctor since the readings may be changed by the pregnancy.

Please remember: Self-measurement is not the same as medical treatment! You should never change the dose of medicines as prescribed by your doctor!

Before using your OMRON 637IT for the first time

Your blood pressure monitor: the benefits

The OMRON 637IT is a compact fully automatic wrist blood pressure monitor. Operating on the oscillometric principle it measures your blood pressure and pulse rate comfortable and quickly from the wrist. It contains an intelligent system for “fuzzy” controlled inflation, known as “Intellisense”. This is an advanced method of oscillometric measurement. No pre-setting of re-inflation is necessary.

The OMRON 637IT has a Position Sensor. The Position Sensor is able to determine the optimal height of your wrist (heart level) for the blood pressure measurement. Measuring at the heart level is extremely important since measuring at a higher or lower position will give wrong results.

The OMRON 637IT has a large DOT matrix display enabling you to enlarge the digits and showing you graphs. Together with the USB computer interface and the built in alarm function for same time measurements or pill intake your OMRON 637IT is the optimal device to manage your blood pressure.

What is blood pressure?

Blood is pumped to artery by the beat (contraction and expansion) of a pump called the heart. The pressure to pump out blood to artery is called the "systolic blood pressure."

The pressure when the heart expands as the blood having circulated the whole body returns is called the "diastolic blood pressure."

Systolic blood pressure

Blood is pumped out.

Artery

Vascular wall

Contraction

Pressure to vascular wall increases.

Diastolic blood pressure

Blood returns to heart.

Vascular wall

Expansion

Vein

Pressure to vascular wall drops.

Health and blood pressure

Blood pressure fluctuates being affected by everyday life and age. Hypertension is a sign that can cause dangerous diseases such as cerebral apoplexy or myocardial infarction to occur easily. By understanding the state of your blood pressure, review your health and lifestyle.

Excessive consumption of alcohol,

• There is no universally accepted definition of hypotension. Generally speaking, those with the systolic pressure below 100 mmHg are considered to be hypotension.

Systolic blood pressure

(mmHg)

The World Health Organization (WHO) and the

International Society of Hypertension (ISH) established the Blood Pressure Classification. Use this

Classification as the guide to know the state of your blood pressure. However, if you are concerned with your blood pressure, be sure to follow the instructions of your doctor.

According to the blood pressure classification by the WHO/ISH* (revised in 1999)

* International Society of Hypertension

• This classification is made based on the blood pressure values measured at upper arm by sitting on the chair in the hospital regardless of the age.

Blood pressure at the upper arm and wrist

Wrist Blood Pressure Monitor

Heart

Brachial artery

Wrist artery

(Radial artery)

(Ulnar artery)

Blood pressure is usually measured at brachial artery.

As the wrist arterial vessel is connected to the brachial vessel, wrist blood pressure values are close to brachial ones and reflect the change of brachial blood pressures.

However in case there is a circulatory disorder such as arterial infarction, fairly large difference is observed between the brachial and the wrist blood pressure values.

After consulting with your doctor, use the wrist blood pressure together with the brachial pressure for your health management.

20 21

Diseases influencing blood pressure values

Diabetes, hyperlipemia, or hypertension accelerates arterial sclerosis, which causes dangerous disease such as cerebral apoplexy or myocardial infarction or induces arterial stenosis or peripheral circulatory disorder.

In these cases, the wrist and brachial blood pressure values may differ greatly. (Even in healthy people, a difference of 20 mmHg may occur if the measuring conditions are not proper.

Therefore do not try to diagnose the measurement values by yourself, but be sure to follow the instructions of your doctor.)

In addition, difference of wrist and brachial blood pressure values may somewhat get affected by the physiological conditions at the time of measurement. However, the blood pressure values measured at wrist and upper arm usually fluctuate in the same manner.

Therefore, you can check the fluctuation tendency of blood pressure by measuring the wrist blood pressure.

Differences between blood pressure measured at home and at the doctor’s office

Normally blood pressure measured at home tends to be lower than when measured at the doctor’s office. This can be as much as 20 mmHg due to that you feel more relaxed at home and feel slightly tense when visiting the doctor. To manage your blood pressure it is important to monitor and register your blood pressure at home.

Since blood pressure is fluctuating from beat to beat and is influenced by daily activities measurements can differ from measurement to measurement.

Maintenance and storage

• For cleaning the monitor only use a soft, lightly moistened cloth.

• Do not use petroleum spirits, thinners or similar solvents!

• Stains on the cuff can be carefully removed using a moist cloth and soapy water.

• Do not wash the cuff or make it wet. Please make sure no water will enter the main unit!

• Keep your monitor in the storage case protected from extreme temperatures and humidity.

• Do not carry out repairs of any kind yourself. If a defect occurs consult your OMRON dealer or distributor.

• Please take the batteries out if the monitor is not used for a long period (app. 2 months or more).

• Electro Magnetic fields can influence the measurement. Do not use a protable phone near the unit.
