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 180(2*90) sets of measurement values with the measuring date and time. You can read the stored data conveniently by pressing the memory button.

The unit comes with the following components:

• Main Unit

• Storage Case

• Instruction Manual printed in English

The unit have the following advanced functions:

• Back Light

• Voice Function

• Positioning Sensor

• Displaying of the date and time

Important Safety Notes

To assure the correct use of the product basic safety measures should always be followed including the precautions listed below:

Read all information in the instruction manual and any other literature included in the box before using the unit.

Contact your physician for specific information about your blood pressure.

Self-diagnosis and treatment using measured results may be dangerous.Follow the instructions of your healthcare provider.

Operate the unit only as intended. Don't use for any other purpose.

The unit is intended to use in measuring blood pressure and pulse rate for adult only, not recommended for neonatal baby at home or medical centre.

Do not use a cellular phone near the unit. It may result in operational failure.

Please avoid using in high radiant area in order to make your measuring data correctly.

Before Taking A Measurement

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.

IHB Introduction

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.

Normal Heartbeat

Pulse

An irregular heartbeat rhythm is defined as a rhythm that varies by less than 25% from the average rhythm or 25% more than the average rhythm detected while the monitor is measuring the systolic and diastolic blood pressure.

Pulse

Irregular Heartbeat

If the Irregular Heartbeat Symbol ( ) displays with your measurement results, we recommend you consult your physician.

Follow the directions of your doctor.

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.

Classification of Blood Pressure

After each measurement is completed, the LCD display will show your position automatically on the six segments of the bar indicator which corresponds to World

Health Organization (WHO) Blood Pressure Indicator.

*Note!

When a person’s systolic and diastolic pressures fall into different categories, the higher category should apply.

27


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.

26


Classification of 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.

28

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.


Error Indicators
