6. 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.
