The standard blood pressure of 120/80. Depending on the age, these figures can change significantly. For example, normal pressure have a one year old baby are indicators 95/65. A person in the age from 16-20 years old is considered normal blood pressure from 100/70 to 120/80. From 20 to 40 years – 120/70 - 130/80. Aged 40 to 60 years, rates up to 140/90 are not pathology. After 60 years of blood pressure considered normal if they do not exceed the level of 150/90.
All these figures can be considered the norm, if the person feels good and does not complain of health. However, the world health organization recommends a blood pressure is normal, if the indicators are within the boundaries from 110 to 130 mm Hg. At a pressure of 140 mm Hg the doctor makes a diagnosis of "hypertension". When the border is below 100 mm Hg – hypotension".
To determine the exact blood pressure is possible only in a state of complete rest. Under physical, mental stress indicators can be significantly exceeded.
On blood pressure directly influenced by such factors as: the amount of blood flowing in the vessels per time unit, the capacity of the vessels, the speed of the outflow of blood from the capillaries, the tension of the vascular walls during the filling with blood.
If the cardiovascular system performs its function normally, blood pressure is normal. If there are abnormalities, it will be consistently changed.
With age the walls of blood vessels lose their elasticity, thus significantly changing their tone. Increased tone leads to hypertension, reduced to hypotension. Therefore, the blood pressure systematically or periodically change.
Jumps in blood pressure adversely affect health. Patient prescribe pharmaceutical drugs of directed action, which helps keep blood pressure normal.
