2. 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.
Should the systolic blood-pressure values lie between 140mmHg and 160mmHg and/or the
diastolic blood-pressure values lie between 90mmHg and 100mmHg, 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 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.
