evaluated after consultation with your doctor.
NOTE: To obtain the greatest accuracy from your blood pressure instrument, it is recommended that
the instrument be used within a temperature range of 50°F (10°C) to 104°F (40°C), with a relative
humidity range of 15-90% (non-condensing).
3. Important information on blood pressure and its measurement
3.1. How does high/low blood pressure arise?
Your level of blood pressure is determined in a part of the brain called the circulatory center.
This part of your brain responds to a situation through feedback with 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. Blood vessel width is altered by fine muscles in the blood vessel walls.
The level of arterial blood pressure changes periodically during heart activity: During blood ejec-
tion from the heart (Systole) the value is maximal (systolic blood pressure value). At the end of the
heart’s rest period, Diastole or diastolic blood pressure value, blood pressure falls to a low value.
Blood pressure values must lie within certain normal ranges in order to prevent particular diseases.
3.2 Which values are normal?
Blood pressure is too high if at rest, your diastolic pressure is above 90mmHg and/or the
systolic blood pressure is over 160mmHg. You should bring these values to the attention of
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 between 90mmHg and 95mmHg, please
consult your doctor, and check your blood pressure regularly.
With blood pressure values that are too low, i.e. systolic values under 105mmHg
and/or diastolic values under 60mmHg, please consult your doctor.
Even with normal blood pressure values, a regular self-check with your blood pressure mon-
itor is recommended. In this way you can detect possible changes in your values early and react
appropriately, in consultation with your physician.
If you are undergoing medical treatment to control your blood pressure, please keep a
record of your blood pressure levels 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 discontinue or independently alter the drug doses prescribed by your doctor.
The following standards for assessing high blood pressure in adults have been established by
the National Institutes of Health JNC7.
