Blood pressure is a measurement of the force of blood  flowing against the walls of the

arteries. Arterial blood pressure is constantly  changing   during the course of the cardiac

cycle. The highest pressure in the cycle is called the  SYSTOLIC BLOOD PRESSURE;

the lowest is the  DIASTOLIC BLOOD PRESSURE.  Both pressure readings, the SYS-

are necessary 

to 

enable a physician to evaluate the status of a

patient’s blood pressure. Many factors such as  physical activity, anxiety, or the time of day,

can influence your blood pressure. Blood pressure is typically low in the morning and

increases from afternoon to evening. It is lower in the summer and higher in the winter.

Having one’s blood pressure measured by a doctor in  a  hospital or a clinic, and group

health checks, tend to stimulate nervousness in the subject and may even create high blood

pressure. Also blood pressure varies in accordance with a variety of conditions,, and so

judgement is not possible on the basis of a single measurement. (See Fig. 2)

The blood pressure measured first thing in the morning after getting up, before taking any

food, and with the subject still, is known as the fundamental blood pressure. In practice it

is rather difficult to record the  fundamental  blood pressure, but to come as near as possible

to measuring. the blood pressure in aan  environment that is close to this, is why it is useful

to take the measurement at home.

The highest point of blood pressure; level of blood pressure produced

as your heart beats.

The lowest point of blood pressure; level of blood pressure produced

as your heart rests between beats.

 

Blood pressure is measured in terms of the

height of mercury in a column. Measurements are written one over the other.

For example, a systolic presssure of 120 

 and diastolic pressure of 80

 is expressed as “120 over
