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 ow 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 uctuations during the day even in healthy people.
The uctuations are inuenced by a number of factors - time of day, person’s
condition, physical or mental activity, environment, etc.
