2. General information on blood
pressure
2.1 Significance of blood pres-
sure values
To determine your blood pressure
you need to measure two values:
Systolic (upper) blood pressure:
is produced when the heart
contracts and pumps blood into
the blood vessels.
Diastolic (lower) blood pressure:
this is the value measured when
the heart muscle is dilated and
again fills with blood.
Blood pressure readings are
expressed in mmHg.
The World Health Organisation
(WHO) and the International
Society of Hypertension (ISH) have
developed the following classifica-
tion for blood pressure values:
