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 160mmHg. 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 140mmHg and 160mmHg and/or the diastolic
blood-pressure values lie between 90mmHg and 95mmHg, 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 105mmHg 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-measure-
ments 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.
