Blood pressure is the pressure of the blood flowing through your body. A certain amount of pressure is needed to deliver blood and the nutrients and oxygen it carries to the parts of our bodies and carry the waste products away. Blood pressure can be measured. Through the work of the National Institute of Health and international investigators checking 10′s of thousands of children, we now know what normal blood pressure in children should be. Most visits to your doctor include having a blood pressure measurement performed. Many people have home equipment for measuring their own blood pressure and often you will notice a blood pressure measurement stand at your local drug store.
