as physical effort, anxiety or the time of the day etc. Generally, blood pressu-
re is low in the morning and raises in the afternoon towards the evening. In
summer, blood pressure is lower than in winter.
Why is it a good thing to measure blood pressure at
home
Having one's blood pressure measured by a doctor in a hospital or clinic
environment tends to stimulate nervousness in a patient and may lead to a
higher blood pressure. Blood pressure varies in accordance with a variety of
conditions and so judgment is not always possible on the basis of a single
measurement. Blood pressure measured first thing in the morning after get-
ting up, before eating, and keeping still, is known as the fundamental blood
pressure. In practice it is rather difficult to record the fundamental blood
pressure but measurement at home in the right environment aids this.
A. Blood pressure classification of the WHO
The standards for the determi-
nation 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 course of a day
with measurements taken every 5 minutes. The bold line represents 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.
