General information about blood
pressure
Blood pressure is measured in mmHg (mm
mercury pressure). Blood pressure consists of
two values. Systolic pressure (SYS) is created by
the contractions of the heart muscle, which
pumps the blood into the arteries. Diastolic
pressure (DIA) is created when the heart relaxes
and fills with blood again.The World Health
Organisation (WHO) has laid down the following
standard values with regard to the blood pressure
of adults
High blood pressure is a risk factor
Systolic pressure (SYS) is too high when it
exceeds 160 mmHg and diastolic pressure (DIA)
is too high when it exceeds 95 mmHg.
We speak of 'high blood pressure' when one of
the two pressures exceeds the value mentioned
above.
