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 val-
ues 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 140 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 mmHg and 160 mmHg and/or the
diastolic blood-pressure values lie between 90 mmHg and 95 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 105 mmHg and/or diastolic values under 60 mmHg, like-
wise, 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.
