BLOOD PRESSURE STANDARD
All manuals and user guides at all-guides.com
The U.S. Department of Health and
Human Services and the National
Institutes of Health have developed a
blood pressure standard that identifies
areas of low- and high-risk blood pressure.
This standard, however, is a general
guideline as blood pressure varies among
different people, age groups, etc.
Categories for Blood Pressure Levels in Adults
Stage 2 Hypertension
Stage 1 Hypertension
Prehypertension
Normal
For adults 18 and older who are not on medicine for high blood
pressure, are not having a short-term serious illness, and do not have
other conditions, such as diabetes and kidney disease.
To determine category of risk when systolic and diastolic readings fall
into two areas, use the higher of the two numbers for classification.
There is an exception to the above definition of high blood pressure for
people with diabetes and chronic kidney disease. A blood pressure of
130/80 mmHg or higher is considered high blood pressure for those
individuals.
