2. Important Information on Blood Pressure and its Measurement
2.1. How does high or low blood pressure arise?
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 speed of the heart (Pulse), as well as the width of circulatory blood vessels is
altered.Blood vessel width is controlled 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.
2.2. Which values are normal?
Please refer to the diagram below(Picture-01)

7
Picture-01
There are six grids in the display of device. Please refer to the picture-01-01. Different grids
represent different interval scales of WHO.
Blood pressure is very high if your diastolic pressure is above 90 mmHg and/or your systolic
blood pressure is over 160 mmHg, 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 mmHg
and 159mmHg and/or the diastolic blood pressure values between 90 mmHg and 99mmHg,
consult your physician. Regular self-checks are necessary. If you have blood pressure values
that are too low, (i.e., systolic values under 105mmHg and/or diastolic values under 60 mmHg),
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 drug doses
prescribed by your physician.
Further information
• If your values are mostly normal under resting conditions but exceptionally high under
conditions of physical or psychological stress, it is possible that you are suffering from
so-called “labile hypertension.” Consult your doctor.
• Correctly measured diastolic blood pressure values above 120mmHg require immediate

8
medical treatment.
2.3. What can be done if regular high or low values are obtained?
1) Consult your doctor.
2) 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.
3) 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.
4) There are measures which you can take to reduce and even prevent high blood pressure.

some days later. Take the battery out won’t lead to a record missing.
5. Measurement Procedure
Note: You should always be seated and calm before and during measurement.
5.1. Before measurement:
• Avoid eating and smoking as well as all forms of exertion directly before measurement. These

10
factors influence the measurement result. Find time to relax by sitting in an wristchair in a quiet
atmosphere for about ten minutes before taking a measurement.
• Remove any gwristent that fits closely to your wrist.
• Always measure on the same wrist (normally left).
• Always compare measurements taken at the same time of day, since blood pressure
changes during the course of the day, as much as 13.5-19.5mmHg.
5.2. Common sources of error:
Note: Comparable blood pressure measurements always require the same conditions!
•Conditions should always be quiet.
•All efforts by the user to support the wrist can increase blood pressure. Make sure you are in a
comfortable, relaxed position and do not flex any of the muscles in the measurement wrist
during the measurement. Use a cushion for support if necessary.
• If the wrist artery lies considerably lower or higher than the heart, an erroneously high or low
blood pressure will be measured !
Note: Only use approved cuffs!
• A loose cuff or a sideways protruding air pocket causes false measurement values.
• With repeated measurements, blood accumulates in the wrist, which can lead to false results.
Consecutive blood pressure measurements should be repeated after a 1 minute pause or after
your wrist has been held up in order to allow the accumulated blood to flow away. If you decide
to take your Averaging Mode measurement again, be sure to wait at least one minute
beforehand.
5.3. Fitting the Cuff
Please refer to picture-04
a) Remove all jewelry and watches. The palm of your hand should be facing you. Apply the cuff
so that the display is facing you.
b) The distance between the cuff and the hand should be 1cm.
c) Secure the cuff with the hook and loop adhesive so that it lies comfortably and not too tight.
It should be comfortable.
d) Lay your wrist on a table with your palm upwards. Support your wrist with a cushion so that
the cuff rests at about the same height as the heart. Remain still for 2 minutes, sitting quietly,
before beginning a measurement.
