About Blood Pressure
What is Blood Pressure?
Blood pressure is the pressure exerted on the artery tube 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 the various health problems afflicting people today,
problems associated with high blood pressure are by far
the most common. High blood pressure's dangerously strong
correlation with cardiovascular disease has made measuring
blood pressure a necessity for identifying those at risk.
Blood Pressure Standard:
The World Health Organization (WHO) and National High
Blood Pressure Education Program Coordinating Committee
have developed a blood pressure standard, according to which
areas of low- and high-risk blood pressure are identified. This
standard, however, is a general guideline, and blood pressures
vary between different people, age groups, etc.
