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.
