IMPORTANT INFORMATION
ON BLOOD PRESSURE
AND ITS MEASUREMENT
What Is Blood Pressure?
Blood pressure is the pressure
that your blood extends to the
vascular walls. Blood pressure
is necessary to provide for
constant blood flow inside the
body. Thanks to it the cells
get oxygen that provides for
their normal functioning. The
heart performs the function of a
«pump», sending blood to the
blood vessels. Each heart beat
creates a certain level of the blood pressure.
There are 2 kinds of blood pressure: a systolic (upper) one, which
corresponds to the heartbeat pushing blood into the arteriae; and a
diastolic (lower) one, which means the blood pressure between two
heartbeats.
Blood pressure is subject to fluctuations during the day even in healthy
people. The fluctuations are influenced by a number of factors – time of
day, person’s condition, physical or mental activity, environment, etc.
