WHO Blood Pressure Classifications
Standards for assessment of high or low blood pressure, regardless of age,
have been established by the World Health Organization (WHO) as shown
in the following chart.
Reference Material: Investigation into Adult Diseases Report
by the Ministry of Health and Social Security, 1971.
This chart is only a general guideline. Please contact your
physician to determine your NORMAL BLOOD PRESSURE.
Variations in Blood Pressure
Blood pressure can be influenced by many factors. This change can occur
from moment to moment. Normally, blood pressure is lowest during the
sleeping period and rises during the day. The graph below represents the
variations in blood pressure shown over a day with measurements taken
every 5 minutes.
The dotted line represents the
sleep period. The rise in blood
pressure at 1 PM
(A in the
graph)
corresponds to a stress-
ful occurrence and at 7 PM
(
B in the graph)
a period of
exercise.
