2. Important Information on Blood Pressure and its Measurement

Version Number: 1.0
---------------------------------------------------------------------------------------------------------------------------
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 at the highest (systolic blood pressure value). At the end of the heart’s “rest period”
(Diastole) pressure is at the 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)
Picture-01
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.”

Version Number: 1.0
Consult your doctor.
• Correctly measured diastolic blood pressure values above 120mmHg require immediate 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.

Version Number: 1.0
hear the notice and background music.). After the measurement, the device will read the blood pressure and
pulse result only.
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
factors influence the measurement result. Find time to relax by sitting in an armchair in a quiet
atmosphere for about ten minutes before taking a measurement.
• Remove any garment that fits closely to your upper arm.
• Always measure on the same arm (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 20-40 mmHg.
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 arm can increase blood pressure. Make sure you are in a
comfortable, relaxed position and do not flex any of the muscles in the measurement 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 25-30cm difference in height between your heart and the cuff results in a
measurement error of 10 mmHg!
• 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.
Cuff works Under the pressure range 0-299mmHg
The wide range rigid cuff is : 9.1” – 14.2” (23-36 cm)
• 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.
5.3. Fitting the Cuff
Please refer to picture-06
a) The cuff is pre-formed for easier use. Remove tight or bulky clothing from your upper arm.
b) Wrap the cuff around your upper left arm. The rubber tube should be on the inside of your arm extending
downward to your hand. Make certain the cuff lies approximately 0.39” to 0.79” (1 to 2 cm) above the elbow.
Important! The red mark on the edge of the cuff (Artery Mark) must lie over the artery which runs down the
inner side of the arm.
c) To secure the cuff, wrap it around your arm and press the hook and loop closure together.
d) There should be little free space between your arm and the cuff. You should be able to fit 2 fingers
between your arm and the cuff. Cuffs that don’t fit properly result in false measurement values. Measure your
arm circumference if you are not sure of proper fit.

Version Number: 1.0
e) Lay your arm on a table (palm upward) so the cuff is at the same height as your heart. Make sure the tube
is not kinked.
f) Remain seated quietly for at least two minutes before you begin the measurement.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in
meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
