Introduction
Thank you for purchasing Fully Automatic Wrist Style Digital Blood Pressure
Monitor.
The unit uses the oscillometric method of blood pressure measurement. It
means the unit detects the movement of your blood through your brachial
artery, and converts your blood pressure into a digital reading. The unit is
simple to use because a stethoscope is not needed while using an
oscillometric monitor.
The unit stores automatically 60 sets of measurement values . You can read
the stored data conveniently by pressing the memory button.

1.Avoid eating,drinking alcohol, smoking, exercising and bathing for
30 minutes before taking a measurement.
2.Stress raises blood pressure.Avoid taking measurements during
stressful times.
3.The cuff can be applied to your left or right wrist.Always measure
your blood pressure on the same wrist.
4.Measurements should be taken in a quiet place.
5.Position the unit at heart level throughout the measurement.
6.Remain still and do not talk during the measurement.
7.Keep a record of your blood pressure and pulse readings for your
physician.A single measurement does not provide an accurate
indication of your true blood pressure.You need to take and record
several readings over a period of time.Try to measure your blood
pressure at the same time each day for consistency.
8.Wait 30~60 seconds between measurements.The wait time allows
the arteries to return to the condition prior to taking the blood
pressure measurement.You may need to increase the wait time
depending on your individual physiological characteristics.
)
When the unit detects an irregular rhythm two or more times during the
measurement, the Irregular Heartbeat Symbol will appear on the
display with the measurement values.

About Blood Pressure
About Blood Pressure
Blood Circulation
The blood circulation is responsible for supplying the body with oxygen.
blood pressure is the pressure exerted on the arteries.
The systolic blood pressure value (higher pressure or top value) represents
the blood pressure produced by contraction of the heart muscle.
The diastolic blood pressure value (lower pressure or lower value) represents
the blood pressure produced by relaxation of the heart muscle.
Systolic Blood Pressure
Diastolic Blood Pressure
Contraction of
the heart muscle
The incidence of hypertension increases with age. In addition, a lack of exercise,
excess body fat and high levels of cholesterol (LDL), which sticks to the inside in
blood vessels, reduces elasticity of these vessels. Hypertension accelerates arterial
sclerosis which can lead to very serious conditions such as stroke and myocardial
infarction. For these reasons it is very important to know whether the blood
pressure is within a healthy range. Blood pressure fluctuates from minute to minute,
throughout the day. Therefore it is essential to take regular measurements to help
you identify an average blood pressure.

High blood pressure can go unnoticed
for a long time, since it doesn’t cause
noticeable symptoms. The following
are all possible causes of abnormally
high blood pressure:
Overweight;
High cholesterol level;
Smoking;
Excessive alcohol consumption;
Stress and emotional upset;
Excessive consumption of salt;
Lack of physical exercise;
Genetic / hereditary predisposition;
Underlying illnesses, such as kidney
disorders or endocrine disturbance.
If your blood pressure reaches upper
values of 140~160 mmHg and lower
values of 90~95 mmHg in repeated
measurements over several days, you
should consult your doctor for detailed
medical examination. You can assist
the treatment prescribed by your
doctor in the following ways:
Loose weight and lower your
cholesterol level;
Reduce the consumption of alcohol;
Reduce the intake of salt;
Stop smoking;
Take regular exercise;
Monitor your blood pressure.
