7. Some Useful Information about Blood Pressure
Classification of Blood Pressure by the World Health Organization
The World Health Organization (WHO) and the
International Society of Hypertension (ISH) developed
the Blood Pressure Classification shown in this figure.
This classification is based on the blood pressure
values measured on people in a sitting position in
outpatient departments of hospitals.
Note:
There is no universally accepted definition of
hypotension. However, those having the systolic
pressure below 100 mmHg are assumed as
hypotensive.
