Classification of Blood Pressure by the World Heath
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.
* There is no universally accepted definition of hypotension.
However, those having the systolic pressure below 100
mmHg are assumed as hypotensive.
