Blood pressure is the pressure or the force of blood
owing against the walls of the arteries. Blood pressure is
constantly changing during the course of the cardiac cycle.
Systolic blood pressure is the highest pressure in the cycle.
Diastolic blood pressure is the lowest pressure in the cycle.
Both pressure readings, the Systolic rate and the Diastolic
rate, are information for the physician to evaluate the status
of patient's blood pressure. Many factors such as physical
activities, anxieties, time of day, can inuence one's blood
pressure. Blood pressure is typically low in the morning and
increases from afternoon to the evening. It is lower in the
summer and higher in the winter.

What is blood pressure ?
Because having one's blood pressure measured by a
doctor in a hospital, or clinic tends to stimulate nervousness
in a person and may cause the blood pressure to rise.
Also, blood pressure changes in different conditions, so
judgement on the basis of single measurement is not
reliable.
The blood pressure measured rst thing in the morning
after getting up, before taking any food is known as the
fundamental blood pressure. So it is useful to take blood
pressure at home.
Why is it useful to measure
blood pressure at home ?

Why is it useful to measure
blood pressure at home ?
Standards for assessing
high or low blood pressure
without regard to age have
been established by the World
Health Organization (WHO)
as shown in the chart.
Variations in blood pressure
Individual blood pressures vary greatly on a daily and
seasonal basis. These variations are even more pronounced
in hypertension patients. Normally the blood pressure rises
while at work and is at its lowest during sleep.
(hypertension: 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 ve
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.
