A. Blood pressure classification of the WHO
The standards for the deter-
mination of high or low blood
pressure independently from
the patient’s age – as shown
ion the table – were determi-
ned by the World Health
Organization (WHO).
B. Variations of blood pressure
Individual blood pressure is subject
to variations on a day-to-day basis
or in relation to the time of the year.
These variations are more percep-
tible in patients with high blood
pressure. Usually, blood pressure
is higher during work and is lowest
in the night when sleeping.
The figure to the right shows the variations of the blood pressure in the cour-
se of a day with measurements taken every 5 minutes. The bold line repre-
sents the sleep phase. The increase in blood pressure at 4 pm (shown as
letter ‘A’ in the figure) and at midnight (shown as letter ‘B’ in the figure) mark
pain events of the patient.
