2. IMPORTANT INFORMATION ON THE SUBJECT OF
BLOOD-PRESSURE AND ITS MEASUREMENT
2.1. How does High/Low Blood-Pressure arise?
As your heart beats, it pumps your blood round your body so that your muscles
can get all the energy and oxygen they need. To do this, your heart pushes your
blood through a network of blood vessels called arteries. As the blood travels
through the arteries it pushes against the sides of these blood vessels and the
strength of this pushing is called your blood pressure. As your heart squeezes
and pushes your blood through your arteries, your blood pressure goes up. As
your heart relaxes, your blood pressure goes down. So, with each heartbeat,
your blood pressure will rise to a maximum level and then fall to a minimum
level.
2.2. Which values are normal?
Blood pressure is too high if at rest, the diastolic pressure is above 90 mmHg
and/or the systolic blood-pressure is over 160 mmHg. 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. Should the systolic blood-pressure values lie between 140 mm Hg and
159 mmHg and/or the diastolic blood-pressure values lie between 90 mmHg
and 99 mmHg, likewise, please consult your doctor. Furthermore, regular self-
checks will be necessary. With blood-pressure values that are too low, i.e.
systolic values under 100 mmHg and/or diastolic values under 60 mmHg,
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.

·
The application of the cuff and its pressurization on any limb where
intravascular access or therapy, or an arteriovenous (A-V) shunt, is present
because of temporary interference to blood flow and could result in injury to
the patient.
·
Do not let the cuff and its pressurization on the arm on the side of a
mastectomy.
·
The need to check that operation of the automated sphygmomanometer does
not result in prolonged impairment of patient blood circulation.
·
Not intended to be used together with HF surgical equipment.
·
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.
·
The pulse display is not suitable for checking the frequency of heart
pacemakers!
·
In cases of cardiac irregularity (Arrhythmia), measurements made with this
instrument should only be evaluated after consultation with the doctor.
Electromagnetic interference
The device contains sensitive electronic components (Microcomputer).
Therefore, avoid strong electrical or electromagnetic fields in the direct vicinity of
the device (e.g. mobile telephones, microwave cookers). These can lead to
temporary impairment of the measuring accuracy.
