Understanding and Classification of Blood Pressure

What is meant by Blood Pressure is the amount of blood pressure suppressed against the artery wall (artery) when the Heart pumps blood throughout the human body. Blood pressure is one of the important measurements in maintaining the health of the body, because high blood pressure or hypertension in the long term will cause the stretch of artery walls and result in rupture of blood vessels. Rupture of blood vessels is what causes the occurrence of Stroke. Some diseases caused by high blood pressure include Stroke, Heart Disease, Kidney Disease and Aneurysms.

In general, hypertension or high blood pressure does not show symptoms or signs that mean that a patient with hypertension is very difficult to know if he had high blood pressure. Therefore, everyone is encouraged to check their blood pressure regularly and periodically.

There are 2 (two) important measurements in blood pressure, namely Systolic Pressure and Diastolic Pressure.

Systolic Pressure (Systolic Pressure) is a Blood Pressure when the Heart beats and pumps blood.
Diastolic pressure (Diastolic) is the blood pressure when the Heart rests between the beats.

Blood Pressure Classification for Adults


Systolic Pressure, mm Hg

Diastolic Pressure, mm Hg



90 – 119

60 – 79


120 – 139

80 – 89

Hypertension Level 1

140 – 159

90 – 99

Hypertension Level 2

160 – 179

100 – 109

Hypertension Emergency Level

≥ 180

≥ 110

Based on the Table of Blood Pressure Classification above, Normal Blood Pressure is ranged from 90mmHg to 119mmHg for Systolic Pressure while for Diastolic Pressure is about 60mmHg to 79mmHg. Blood pressure below 90/60 mmHg is categorized as Hypotension (Hypotension) or Low Blood Pressure, whereas above 140 / 90mmHg has been categorized as High Blood Pressure or Hypertension.

Generally, after doctors and nurses check our blood pressure, they will tell us the results of Blood Pressure measurements by mentioning the Systolic Pressure and Diastolic Pressure both orally and in writing. For example 120/80. From the sample numbers, we can see that the Systolic Pressure is 120mmHg and the Diastolic Pressure is 80mmHg.

To prevent High Blood Pressure, we need to live a healthy lifestyle by avoiding or stopping smoking, reducing excessive Salt and Sodium consumption, limiting Alcohol consumption, maintaining weight, eating high fiber foods (vegetables and fruits) and exercising regularly.
