2. IMPORTANT INFORMATION ON BLOOD PRESSURE
AND ITS MEASUREMENT
2.1. How does high or low blood pressure arise?
Your level of blood pressure is determined in the circulatory center
of the brain and adjusts to a variety of situations through feedback
from the nervous system.
To adjust blood pressure, the strength and speed of the heart
(Pulse), as well as the width of circulatory blood vessels, is altered.
Blood vessel width is controlled by fine muscles in the blood vessel
walls.
Your level of arterial blood pressure changes periodically during
heart activity:
•
during the “blood ejection” (Systole) the value is highest
(systolic blood pressure value).
•
At the end of the heart’s “rest period” (Diastole) pressure is
lowest (diastolic blood pressure value).
Blood pressure values must lie within certain normal ranges in order
to prevent particular diseases.
Conversely, if the measured pressure values are outside the normal
defined values, it can be a sign of some pathology and therefore
require to be promptly communicated to your doctor who will
evaluate them appropriately.
