About Blood Pressure
A. Standards for assessment of high or low blood pressure
without regard to age, have been established by the WHO,
and classifications adapted from JNC7:
WHO: World Health Organization
JNC 7: The Seventh Report of the Joint National Committee on
Prevention, Detection, Evaluation, and Treatment of High Blood
Pressure. NIH Publication No.04-5230 August 2004
However the above chart is not exact for classification of blood
pressure and it's intended to be used as a guide in
understanding non-invasive blood pressure measurements.
Please consult with your physician for proper diagnosis.
B. Variations in blood pressure:
Individual blood pressures vary greatly both on a daily and a
seasonal basis. These variations are even more pronounced in
hyper tense patients. Normally the blood pressure rises while at
work and is at its lowest during sleeping period.
(hyper tense: means a person who has high blood
pressure symptom.)
The graph below illustrated the
variations in blood pressure over a
whole day with measurement taken
every five minutes.
The thick line represents sleep. The
rise in blood pressure at 4 PM (A in
the graph) and 12 PM (B in the graph) correspond to an attack of
pain.
