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 dis-
eases. Therefore, blood pressure monitoring is important
for identifying those at risk.
BLOOD PRESSURE STANDARD
The table on the next page contains defined levels for
hypertension that are publicly available from the National
Heart Lung and Blood Institute at the U.S. National Institutes
of Health (NIH)
.
(http://www.nhlbi.nih.gov/health/dci/Diseases/Hbp/HBP_WhatIs.html)
Users can compare their own blood pressure readings
against these defined levels to determine if they may be
potentially at increased risk.
