Blood Pressure Standard
The Joint National Committee on prevention, detection, evalua-
tion, and treatment of high blood pressure has developed a blood
pressure standard, according to which areas of low and high risk
blood pressure are identified. This standard is a guideline as blood
pressure varies among different people and different age groups...
It is important that you consult with your physician regularly.
Your physician will tell you your normal blood pressure range as
well as the point at which you will be considered at risk.
