General information about blood pressure
• Blood pressure is the force with which the bloodstream
presses against the arterial walls. Arterial blood pressure
constantly changes in the course of a cardiac cycle.

• Blood pressure is always stated in the form of two values:
- The highest pressure in the cycle is called systolic
blood pressure. This arises when the heart muscle
contracts and blood is pumped into the blood vessels.
- The lowest is diastolic blood pressure, which is when
the heart muscle has completely stretched back out
and the heart fills with blood.
• Fluctuations in blood pressure are normal. Even during
repeat measurements, considerable differences between
the measured values may occur. One-off or irregular
measurements therefore do not provide reliable informa-
tion about the actual blood pressure. Reliable assess-
ment is only possible when you perform the measure-
ment regularly under comparable conditions.
Risk indicator
The World Health Organization (WHO) has defined the in-
ternationally recognised classification for the evaluation of
measured blood pressure values listed in the table below:
