Tool to check the blood pressure is also known as sphigmomanometer tensimeter. There are digital and there is also tensimeter tensimeter mercury that is still commonly used for clinical examinations.
Checking Blood Pressure
When checking blood pressure, there are two numbers that are usually referred to as 120/80. What are these numbers?
Systolic
The first number (120), ie systolic blood pressure, the pressure when the heart beats or beats (systole). Often called the pressure on.
Diastolic
The first number (90) is diastolic blood pressure, the pressure when the heart is resting between when pumping. Often referred to under the pressure.


The doctor will perform blood pressure checks by having you sit or lie down, because it was the best position to measure blood pressure.

Blood pressure is created by taking two measurements and usually there are two numbers that will be referred by a physician. For example doctors call 140-90, it means it is 140/90 mmHg. The first number (140) showed upward pressure due to pulsation of the arteries when the heart or heart beat or beats, and is called the systolic pressure or pressure is often called upon.

Once you know your blood pressure, you definitely want to know if you include low blood pressure, normal or high. The following blood pressure classification based on figures measured by tensimeter for systolic and diastolic blood pressure:

Blood Pressure	Sistolik (first number)	Diastoli (second number)
Low blood or hypotension	under 90	UNDER 60
Normal	90 - 120	60 - 80
Pre-hypertension	120 - 140	80 - 90
High blood pressure or hypertension (stage 1)	140 - 160	90 - 100
