2. Important information about blood pressure and its measurement
2.1. How does high/low blood pressure arise?
Your level of blood pressure is determined in the circulatory center of the
brain and adjusts to a variety of situations through feedback from the ner-
vous system. To adjust 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 affected by way of fine muscles in the blood vessel
walls. Your level of arterial blood pressure changes periodically during
heart activity. During the "blood ejection" (Systole), the value is highest
(systolic blood pressure value). At the end of the heart’s "rest period"
(Diastole), pressure is lowest (diastolic blood pressure value). Your blood
pressure values must lie within certain normal ranges in order to prevent
particular diseases.
2.2. Which values are normal?
Blood pressure is very high if your diastolic pressure is above 100 mmHg
and/or your systolic blood pressure is over 160 mmHg,
while at rest . In
this case, please consult your physician immediately. Long-term values at
this level endanger your health due to continual damage to the blood ves-
sels in your body.
If your systolic blood pressure values are between 140 mmHg and 159
mmHg and/or the diastolic blood pressure values are between 90 mmHg
and 99 mmHg, consult your physician. Regular self-checks are necessary.
If you have blood pressure values that are too low (i.e., systolic values
under 105 mmHg and/or diastolic values under 60 mmHg), consult your
physician.
