For further questions on the subject of blood pressure and its measurement, please contact your doctor.
Attention!
1.2. Important information about self-measurement
Do not forget: self-measurement means control, not diagnosis or treatment. Unusual values must always be discussed with your doctor. Under no circumstances should you alter the dosages of any drugs prescribed by your doctor.
Important information on the subject of blood pressure and its measurement
2.1. How does high/low blood pressure arise?
The level of blood pressure is determined in a part of the brain, the so- called circulatory centre, and adapted to the respective situation by way of feedback via the nervous system. To adjust the blood pressure, the strength and frequency of the heart (Pulse), as well as the width of circulatory blood vessels is altered. The latter is effected by way of fine muscles in the blood-vessel walls.
The level of arterial blood pressure changes periodically during the heart activity: During the «blood ejection» (Systole) the value is maximal (systolic blood pressure value), at the end of the heart’s «rest period» (Diastole) minimal (diastolic blood pressure value). The blood pressure values must lie within certain normal ranges in order to prevent particular diseases.
2.2 Which values are normal?
Blood pressure is too high if at rest, the diastolic pressure is above 90mmHg and/or the systolic blood pressure is over 140mmHg. In this case, please consult your doctor immediately. Long-term values at this level endanger your health due to the associated advancing damage to the blood vessels in your body.
With blood pressure values that are too low, i.e. systolic values under 100mmHg and/or diastolic values under 60mmHg, likewise, please consult your doctor.
Even with normal blood pressure values, a regular self-check with your blood pressure monitor is recommended. In this way you can detect possible changes in your values
early and react appropriately.
If you are undergoing medical treatment to control your blood pressure, please keep a record of the level of your blood pressure by carrying out regular self-measurements at specific times of the day. Show these values to your doctor. Never use the results of your measurements to alter independently the drug doses prescribed by your doctor.
Table for classifying blood pressure values (units mmHg) according to World Health Organization:

Range| Systolic Blood pressure| Diastolic Blood pressure| Measures
---|---|---|---
Hypotension| lower than 100| lower than 60| Consult your doctor
Normal range| between 100 and 140| between 60 and 90| Self-check
Mild hypertension| between 140 and 160| between 90 and 100| Consult your doctor
Moderately serious hypertension| between 160 and 180| between 100 and 110| Consult your doctor
Serious hypertension| higher than 180| higher than 110| Consult your doctor immediately

☞ Further information

• If your values are mostly standard under resting conditions but exceptionally high under con- ditions of physical or psychological stress, it is possible that you are suffering from so-called «labile hypertension». Please consult your doctor if you suspect that this might be the case.
• Correctly measured diastolic blood pressure values above 120 mmHg require immediate medical treatment.

2.3. What can be done, if regular increased/low values are obtained?
a) Please consult your doctor.
b) Increased blood pressure values (various forms of hypertension) are associated long- and medium term with considerable risks to health. This concerns the arterial blood vessels of your body, which 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 be the result. Furthermore, with long-term continuously increased blood pressure values, the heart will become structurally damaged.
c) There are many different causes of the appearance of high blood pressure. We differentiate between the common primary (essential) hypertension, and secondary hypertension. The latter group can be ascribed to specific organic 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, not only for reducing a medically established high blood pressure, but also for prevention. These measures are part of your general way of life:

A) Eating habits

• Strive for a normal weight corresponding to your age. Reduce overweight!
• Avoid excessive consumption of common salt.
• Avoid fatty foods.

B) Previous illnesses
Follow consistently any medical instructions for treating previous illness such as:

• Diabetes (Diabetes mellitus)
• Fat metabolism disorder
• Gout

C) Habits

• Give up smoking completely
• Drink only moderate amounts of alcohol
• Restrict your caffeine consumption (Coffee)

D) Physical constitution

• After a preliminary medical examination, do regular sport.
• 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 sporting activities. He will advise you regarding the type and extent of types of sport that are possible for you.

The various components of the Aneroid Blood Pressure Kit
The illustration shows the BP AG1-30, consisting of:

Carrying out a measurement

4.1. Before the measurement

• Avoid eating, smoking as well as all forms of exertion directly before the measurement. All these factors influence the measurement result. Try and find time to relax by sitting in an armchair in a quite atmosphere for about ten minutes before the measurement.
• Remove any garment that fits closely to your upper arm.
• Measure always on the same wrist (normally left).
• Attempt to carry out the measurements regularly at the same time of day, since the blood- pressure changes during the course of the day.

4.2. Common sources of error
Note: Comparable blood pressure measurements always require the same conditions! These are normally always quiet conditions.

• All efforts by the patient to support the arm can increase the blood pressure. Make sure you are in a comfortable, relaxed position and do not activate any of the muscles in the measu rement arm during the measurement. Use a cushion for support if necessary.
• If the arm artery lies considerably lower (higher) than the heart, an erroneously higher (lower) blood pressure will be measured! (Each 15cm difference in height results in a measurement error of 10mmHg!)
• Cuffs that are too narrow or too short result in false measurement values. Selecting the cor rect cuff is of extraordinary importance. The cuff size is dependent upon the circumference of the arm (measured in the centre). The permissible range is printed on the cuff. If this is not suitable for your use, please contact your dealer. Note: Only use clinically approved Original-Cuffs!
• A loose cuff or a sideways protruding air-pocket causes false measurement values.

4.3. Fitting the cuff
a) Push the cuff over the left upper arm so that the tube points in the direction of the lower arm. b) Lay the cuff on the arm as illustrated. Make certain that the lower edge of the cuff lies approximately 2 to 3 cm above the elbow and that the rubber tube leaves the cuff on the inner side of the arm. Important! The mark (ca. 3 cm long bar) must lie exactly over the artery which runs down the inner side of the arm. c) Tighten the free end of the cuff and close the cuff with the closer.
d) There must be no free space between the arm and the cuff as this would influence the result. Clothing must not restrict the arm. Any piece of clothing which does (e.g. a pullover) must be taken off. e) Secure the cuff with the closer in such a way that it lies comfortably and is not too tight. Lay the arm on the table (palm upwards) so that the cuff is at the same height as the heart. Make sure that the tube is not kinked. f) Remain seated quietly for two minutes before you begin the measurement.
Comment:
If it is not possible to fit the cuff to the left arm, it can also be placed on the right one. However all measurements should be made using the same arm.
4.4. Measuring procedure
4.4.1. Connect stethoscope tubing to the chestpiece
After the cuff is properly worn on the arm, connect stethoscope tubing of to the chestpiece attached on the cuff. Make sure the chestpiece is in contact with skin and above the brachial artery.
Wear the binaural (earpieces) properly to check the Korotkoff’s sound during measurement.
Before using the stethoscope, be sure there is no crack on the diaphragm, earpieces, and tubing. Any improper setup or damage of the stethoscope will cause distorted sound or poor sound transmission to make inaccurate reading. 4.4.2. Inflating the cuff
Close the air valve on the bulb by turning the screw clock wise.
Do not over-tighten. Squeeze the inflation bulb with the hand at a steady rate until the pointer on the gauge is 30 mmHg above your normal systolic pressure value. If you are not sure the value, inflate to 200 mmHg first. 4.4.3. Systolic blood pressure reading
Slowly open air valve by turning screw counter clockwise and hold stethoscope chestpiece over brachial artery. Proper de flation rate is essential for an accurate reading, so you should practice and master a recommended defla tion rate of 2-3 mmHg per second or a drop of 1-2 marks on the pressure gauge each heartbeat. You should not keep the cuff inflated any longer than necessary. As the cuff begins to deflate, you must listen care fully with the stethoscope. Note the reading on the gauge as soon as you hear a faint, rhythmic tapping or thumping sounds. This is the systolic blood pressure reading. Listen care fully and familiarize yourself with pulse (Korotkoff’s) sound. 4.4.4. Diastolic blood pressure reading
Allow the pressure to continue dropping at the same deflation rate. When your diastolic blood pressure value reached, the thumping sound stops. Deflate the cuff valve completely. Remove the cuff from arm and stethoscope from ears.
4.4.5. Record your readings
Repeat the measurement at least two times. Do not forget to record your readings and the time of the day measurement is made immediately after you finish measuring. A suitable time is first thing in the morning, or just before evening meals. Remember that your physician is the only person qualified to analyze your blood pressure.
☞ Further information
Measurements should not occur soon after each other, since otherwise, the results will be falsified. Wait therefore for several minutes in a relaxed position, sitting or lying, before you repeat a measurement.
Other possible malfunctions and their elimination
If problems occur when using the device, the following points should be checked and if necessary, the corresponding measures are to be taken:
Malfunction

The sound transmission is poor, distorted or there is extraneous noise.| Remedy
1.  Check the earpieces if they are plugged or cracked.
If not, make sure they do not fit poorly as worn.
2.  Check the tube if it is broken or twisted.
3.  Check the bell and diaphragm of chestpiece if there is any crack.
4.  Make sure the chestpiece is in proper contact with skin and over brachial artery during measuring.
Clean or replace any defective parts if found to avoid inaccurate reading.
---|---
The pressure does not rise although the bulb is pumping.| 1.  Make sure that the valve is closed.
2.  Make sure the cuff is properly connected to bulb and manometer
3.  Check if the cuff, tube and bulb is leaky. Replace the defective parts if any
The deflation rate can not be set to 2-3 mmHg/ sec. by adjusting the air
release valve.| •  Disassemble the valve from bulb to check if there is any blockage in the airway of the valve. Clean the blockage and try again. If it still does not work, replace it to avoid inaccurate reading.
Pointer is not at 0 +/- 3 mmHg at rest.| 1.  Make sure that the valve is open for zero check.
2.  If still more than 3mmHg deviation, contact your dealer to recalibrate the manometer.

☞ FURTHER INFORMATION
The level of blood pressure is subject to fluctuations even with healthy people. Important thereby is, that comparable measurements always require the same conditions (rest condition)!
If, in spite of observing all these factors, the fluctuations are more than 15mmHg, and/or you hear irregular pulses on several occasions, please consult your doctor.
You must consult your specialist dealer or chemist if there are technical problems with the blood pressure instrument. Never attempt to repair the instrument yourself!
Any unauthorised opening of the instrument invalidates all guarantee claims!
