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.

Systolic blood pressure (mmHg)

				Severe hypertension
180
160		Moderate hypertension
		Mild hypertension
140
	Normal systolic value
130	Normal blood
120	pressure
	Optimal blood
	pressure						Diastolic
	(target value)						blood
80			85	90	100	110	pressure
							(mmHg)

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.
