What is Blood Pressure?
The movement of blood throughout the bodies through arteries is very important for a person to stay alive. Blood pressure or movement of blood throughout the body provides oxygen to every organ, tissue, and cells. So, blood pressure is a normal and routine phenomenon of a living body.
It functions when heart pumps blood through the blood vessels, the blood pushes against the walls of the blood vessels that create blood pressure. Healthy arteries (arteries are the blood vessels) carry oxygen-rich blood from the heart to the rest of the body.
Arteries are normally stretchable and hence it allows more blood to push through them. The stretchiness of arteries depends on how hard the blood pushes against the artery walls. For the healthy arteries, it is important to keep the blood pressure within a healthy range.
How is Blood Pressure Diagnosed or Measured?
Sphygmometer is a device used to measure the blood pressure. It is a blood pressure monitor that measures two numbers in the form of numerator and denominator as shown in the example given below:
120 is the top number that measures the force of blood in the arteries when the heart contracts (beats). This process is known as ‘SYSTOLIC’ pressure.
80 is the bottom number that measures the force of blood in your arteries while the heart is relaxed (filling the blood between beats). This process is known as ‘DIASTOLIC’ pressure. It is measured in ‘mmHg’ (measuring unit).
What is Normal Blood Pressure?
Normally, the normal blood pressure varies from moment to moment; however, the two digits (i.e. 120 and 80) are the normal figure of a normal person. For the people with diabetes or kidney disease, blood pressures lower than 130/80 is good and lower than 120/80 is ideal.
Types of Blood Pressure:
The following table illustrates the low, normal, and high blood pressure conditions:
Among the five different types of Blood Pressures, two are the major Blood Pressures, which are commonly seen in most of the people and are mostly affected by different age groups.
However, for more detailed information, following are the two types of Blood Pressures:
