Blood pressure is the force that allows blood flow to the heart throughout the body.
When the heart contracts, blood pressure is maximum. This value is called systolic pressure, it is the figure measurably higher.
When the heart relaxes between beats, blood pressure is minimal. This value is called diastolic pressure, it is the figure measurably lower.
How blood pressure is measured?
Blood pressure is measured by placing an inflatable cuff around the arm and detecting the systolic and diastolic pressure, or by detection of arterial sounds (auscultatory method) or by detection of arterial oscillations (oscillometric method).
