How to define hypertension and hypotension?
Dec 28, 2017

Normal blood pressure is the premise of blood circulation flow. Either hypertension or hypotension would do harm to body.

Many families have bought aneroid sphygmomanometers, stethoscopes or digital blood pressure monitors to monitor blood pressure of family members at home.

What blood pressure is hypertension? What blood pressure is hypotension?

Are there any relations between blood pressure and ages.

First, please check a blood pressure table as follows,

 

Blood pressure category table

Blood pressure types

Systolic pressure

(mmHg)

Diastolic pressure(mmHg)

Ideal blood pressure

130~139

85~90

Mild hypertension(first level)

140~159

90~99

Subgroup(borderline hypertension)

140~149

90~94

Medium hypertension (second level)

160~179

100~109

High hypertension ( third level)

≧180

The above data is average normal blood pressure of Chinese in 1986.

We can find the following regulations from above table:

1. At the same age grades, blood pressure of male is higher than that of female.

2. Blood pressure increases with the ages.

 

With the improvement of living standards, the average blood pressure also increases.

And situations in different countries vary a bit as well. So, the above table can be treated as a blood pressure reference table.
