Foreword:
At present, about 270millionpeople around the world have hypertension, one of the diseases that seriously affect people’s health. Massive clinical practice and medicine research over decades  have brought up effective measures for the prevention and treatment of hypertension, but due to the “low awareness rate, low medication rate and low control rate”, hypertensioncontributes to  a large portion of disability and mortality very year.If you have hypertension, the WHO recommended checking your blood pressure regularly, and taking medication to control the blood pressure. You can live with ease if your blood pressure can be controlled at the reasonable level. Monitor your blood pressure, and follow the doctor’s order on medication to prevent  complications, that is all you need to do to enjoy your life like anyone who is not suffering hypertension. If your blood pressure is stable, it is recommended to measure it once a day; if your  blood pressure fluctuates, measure it three times a day or follow the doctor’s advice.These simple precautions can greatly reduce the potential hazards posed by hypertension.

Chapter 4 Measuring Blood Pressure

4.1 Preparing to take a measurement
In order to ensure the accuracy of the measurement results, follow there commendations listed below:

• Do not eat, drink, smoke or exercise before the measurement. Try to have a rest of 10 minutes before taking the blood pressure. Please keep relax as much as possible and not talk during the measurement procedure
• Do not move your arm and remain still until the entire measurement process is completed. Avoid measuring when you are emotionally stressed.
• Do not wear thick clothing. Expose the arm for about five inches above the elbow. Remove any restrictive clothing  from the arm.
• Take a rest of at least 30 seconds between two measurements, so that the blood pressure could return to the state before measurement. You can extend the waiting time according to your  physical conditions.
• Try to measure blood pressure regularly at the same time of the day, because blood pressure changes naturally many  times a day.

4.2 Common errors
Note: Comparable blood pressure measurements always require the same conditions. Conditions should always be quiet.

• All efforts by the user to support the arm can increase blood pressure. Make sure you are in a comfortable, relaxed position and do not flex any of the muscles in the measure- ment arm  during the measurement. Use a cushion for support if necessary.
• If the arm artery lies considerably lower or higher than the heart, an erroneously high or low blood pressure will be measured. Each 15 cm (6”) difference in height between your heart and  the cuff results in a measurement error of 10 mm Hg.
• Cuffs that are too narrow or too short result in false measurement values. Selecting the correct cuff is extremely important. Cuff size is dependent upon the circumference of the arm  (measured in the center). The permissible range is printed on the cuff.
• A loose cuff or a sideways protruding air pocket causes false measurement values.
• With repeated measurements, blood accumulates in the arm, which can lead to false results. Consecutive blood pressure measurements should be repeated after a 1 minute pause or after  your arm has been held up in order to allow the accumulated blood to flow away.

4.3 How to use the cuff
Arm circumference should be measured with a measuring tape in the middle of the relaxed upper arm and make sure the maximum measurement size of the selected cuff must be larger than the arm circumference

1. Insert the cuff air jack into the port on the main body.
2. Wrap the cuff around a bare arm (roll up your sleeve or wear short sleeves). The air outlet of the tube should be on the extension line of the middle finger.
3. It is recommended to took blood pressure on your left arm since the arm is more relaxed, but you can also use your right arm.
4. The cuff should not be too loose or too tight. It is appropriate to leave a finger’s distance between the cuff and arm. Keep the bottom of the cuff 1cm~2cm above the elbow.
   • Do not bend the cuff and air tube forcefully.
   • When removing the air tube from the main body, hold the connector rather than the tube.
   • Do not inflate the cuff before wrapping the cuff around your arm.
   • If the cuff is leaking, replace it in time.
   • In order to measure blood pressure accurately, use the cuff provided by the manufacturer. Non-original parts may cause measurement error.

Comment
If it is not possible to fit the cuff to your left arm, it can also be placed on your right arm. However, all measurements should be made using the same arm. Comparable blood pressure  measurements always require the same conditions (relax for several minutes before a reading).

4.4 Measurement posture
As shown in the figure below, the cuff should remain at heart level for accurate blood pressure reading. Sit upright and keep your shoulder and arm in relaxed position. Do not move your body  or arm.

1. comfortably seated
2.  legs uncrossed,
3. feet flat on the floor,
4. back and arm supported
5. middle of the cuff at the level of right atrium of the heart

4.5 Measuring blood pressure
After wrapping the cuff properly, you can take your blood pressure with the following steps (mmHg is used in this example):

1. Press the [ON/OFF] button once to select User 1 or User 2, referring to the section3.5 Select the user. All symbols in the LCD display will be lit for 2 seconds.
2. The inflation process starts. The current pressure value is displayed at the low-pressure position, with the pressure rising gradually (Figure 14).
3. When the inflation pressure reaches the maximum value, the inflation motor stops working and the pressure will be released in steps. During the measuring process, the air pressure in the  cuff is displayed on the LCD display (Figure 15).
4. When the pulse rate is detected, a flashing symbol“ ” appears on the LCD display (Figure 15).
5. After the measurement is completed, the systolic pressure, diastolic pressure, pulse rate and unit are displayed on the screen, and they are also saved to memory. You will hear the voice announcement of the measurement results if you have turned on the voice switch, as shown in Figure 16. A colored column on the right of the screen indicates the pressure levels, which are defined in Figure 18.
6. If you want to take another measurement, short press the [ON/OFF] button once. Long press the [ON/OFF] button to shut down. If there is no operation, the measurement result is displayed for 1 minute before the device automatically shuts down. It is recommended to take 3 times of blood pressure measurement in a row, with an interval of about 30s between measurements. After three measurements are completed, press the [Memory] button once to view the average value of the measurements (Figure 17).

Note:

• Do not make self-judgment based on the measured results. Consult a doctor to explain the measured blood pressure and accept the doctor’s guidance.
• A colored column on the right of the screen indicates the pressure levels, which are defined in Figure 18 . The following standards for assessing high blood pressure (in adults) have been  established by the 2018 ESC/ESH Guidelines for the management of arterial hypertension.
• If you experience any discomfort during measurement, such as when the airbag is over-inflated, press the [ON/OFF] button to stop the measurement and turn off the device immediately.
• Repeated measurements cause arm hyperemia, which affects the measurement result. You can take off the cuff and take a rest of 30s before another measurement.

3. Full memory
   When the memory has stored 90 results, a new, measured value is stored by overwriting the oldest value.

4.7 Stop a measurement
If it is necessary to interrupt a blood pressure measurement for any reason (e.g., the patient feels unwell), the [ON/OFF] button can be pressed at any time. The device then immediately lowers  the cuff pressure automatically and enters sleep mode.
4.8 Irregular heartbeat (IHB) detector
The appearance of this symbol indicates that certain pulse irregularities were detected during the measurement. In this case, the result may deviate from your normal basal blood pressure – repeat the measurement. In most cases, this is no cause for concern. However, if the symbol appears on a regular basis (e.g., several times a week with measurements taken daily), we advise  you to tell your doctor.
Please show your doctor the following explanation:
Information on frequent appearance of the irregular heartbeat symbol This instrument is an oscillometric blood pressure monitor device that also analyzes pulse frequency during measurement. The instrument is clinically tested.
If pulse irregularities occur during the measurement, the irregular heartbeat symbol is displayed with the measurement.
If the symbol appears frequently or if it suddenly appears more often than usual, we recommend the patient seek medical advice.
The instrument does not replace a cardiac examination but serves to detect pulse irregularities at an early stage.
4.9 Charging
If your model uses a built-in removable lithium battery, do not replace it without authorization. When necessary, ask a professional to replace the battery. Use the supplied power supply cable  and the DC adaptor (6V, 600mA) to charge the lithium battery.

2. Record the daily changes of your blood pressure values and consult a doctor.

NOTE

• A healthy person may also have fluctuating blood pressures. The important thing is that you must be quiet when performing blood pressure measurements, and only compare the values  measured under the same physical and mental conditions.
• If you have performed the above checks and followed the correct measuring method, but the fluctuation of blood pressure values still exceeds 15mmHg or you can hear an uneven  heartbeat rhythm sometimes, please consult a doctor.
• If you encounter any problem when using this device, please consult your local dealer or medical expert. Do not disassemble or repair this productwithout authorization! Any unauthorized disassembly or repair will void the warranty!

Chapter 7 How is blood pressure measured?

7.1 What is blood pressure, and why does it fluctuate?
Your level of blood pressure is determined in the circulatory center of the brain and adjusts to a variety of situations through feedback from the nervous system. To adjust blood pressure, the  strength and frequency of the heart (pulse), as well as the width of circulatory blood vessels is altered. Blood vessel width is affected by fine muscles in the blood vessel walls.
Your level of arterial blood pressure changes periodically during heart activity. During the “blood ejection” (Systole), the value is highest (systolic blood pressure value). At the end of the  heart’s “rest period” (Diastole), pressure is lowest (diastolic blood pressure value). Blood pressure values must lie within certain normal ranges in order to prevent particular diseases.
Blood pressure is too high if your systolic blood pressure is over 160 mm Hg and/or your diastolic pressure is above 100 mm Hg, while at rest. In this case, please consult your physician  immediately. Long-term values at this level endanger your health due to continual damage to the blood vessels in your body.
If your systolic blood pressure values are between 140 mm
Hg and 159 mm Hg and/or the diastolic blood pressure values are between 90 mm Hg and 99 mm Hg, consult your physician. Regular self-checks are necessary.
If you have blood pressure values that are too low (i.e., systolic values under 105 mm Hg and/or diastolic values under 60 mm Hg), consult your physician.
Even with normal blood pressure values, a regular self-check with your blood pressure monitor is recommended. You can detect possible changes in your values early and react appropriately.
If you are undergoing medical treatment to control your blood pressure, keep a record of values along with time of day and date. Show these values to your physician.
Never use the results of your measurements to independently alter the medication prescribed by your physician.

7.2 What can I do to change my blood pressure?
(a) Consult your doctor.
(b) Increased blood pressure values (various forms of hypertension) are associated with considerable health risks over time. Arterial blood vessels in your body are endangered due to  constriction caused by deposits in the vessel walls (arteriosclerosis). A deficient supply of blood to important organs (heart, brain, muscles) can result from arteriosclerosis. Furthermore, the heart will become structurally damaged with increased blood pressure values.
(c) There are many different causes of high blood pressure. We differentiate between the common primary (essential) hypertension and secondary hypertension. The latter group can be  ascribed to specific organ malfunctions. Please consult your doctor for information about the possible origins of your own increased blood pressure values.
(d) There are measures which you can take to reduce and even prevent, high blood pressure. These measures must be permanent lifestyle changes.

1. Eating habits
   • Strive for a normal weight corresponding to your age. See your doctor for your ideal weight.
   • Avoid excessive consumption of common salt.
   • Avoid fatty foods.

2. Previous illnesses
   • Consistently follow all medical instructions for treating illness such as:
   • Diabetes (diabetes mellitus)
   • Fat metabolism disorder ·Gout

3. Habits
   • Give up smoking completely.
   • Drink only moderate amounts of alcohol.
   • Restrict your caffeine consumption (e.g., coffee).

4. Physical constitution
   • After a preliminary medical examination, do regular exercise.
   • Choose sports which require stamina and avoid those which require strength.
   • Avoid reaching the limit of your performance.
   • With previous illnesses and/or an age of over 40 years, please consult your doctor before beginning your exercise routine. You must receive advice regarding the type and extent of exercise that is appropriate for you.

Chapter 8 Maintenance and Calibration
