Blood Pressure Classification

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 the Figure below. (This classification is
made based on the blood pressure values measured in a sitting
position, in the outpatient department of hospital.)
* There is no universally accepted definition of hypotension. However,
those having the systolic pressure below 100 mmHg are assumed as
hypotension.
According to the blood pressure classification by the WHO/ISH* (revised in 1999)
