ABOUT BLOOD PRESSURE
What is Blood Pressure?
Blood pressure is the pressure exerted on the artery
walls while blood flows through the arteries. The
pressure measured when the heart contracts and
sends blood out of the heart is systolic (highest)
blood pressure. The pressure measured when the
heart dilates with blood flowing back into the heart
is called diastolic (lowest) blood pressure.
Why Measure Your Blood Pressure?
Among today’s various health problems, those
associated with high blood pressure are very common.
High blood pressure dangerously correlates with
cardiovascular diseases. Therefore, blood pressure
monitoring is important for identifying those at risk.
