Electromagnetic interference
The device contains sensitive electronic components (Microcomputer). Therefo-
re, avoid strong electrical or electromagnetic fields in the direct vicinity of the de-
vice (e.g. mobile telephones, microwave cookers). These can lead to temporary
impairment of the measuring accuracy.
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 frequ-
ency 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) mini-
mal (diastolic blood-pressure value).
The blood-pressure values must lie within certain normal ranges in order to
prevent particular diseases.
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 mmHg and
160 mmHg and/or the diastolic blood-pressure values lie between 90 mmHg
and 100 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 blo-
od-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.
