BLOOD PRESSURE STANDARD
The table below 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.
This table is applicable to most adults aged 18 and older.
Blood pressure tends to go up and down, even in people
who normally don’t have high readings. If your numbers
stay above the “normal” range most of the time, you may
be at increased risk and should consult your physician.
