Blood Pressure (B.P) is generally defined as the force or the pressure of blood cells against the walls of the arteries during circulation. This pressure decreases progressively with distance from the left ventricle. It is an important force because oxygen and nutrients would not be pushed around our circulatory system to nourish tissues and organs without B.P.
B.P is also vital because it delivers white blood cells and antibodies for immunity, and hormones such as insulin. Both Diastolic and Systolic are derived from the Greek word. Diastolic meaning drawing apart and Systolic meaning a drawing together. Traditionally, It was measured non-invasively using auscultation with either an aneroid gauge or a mercury-tube moderately Sphygmomanometer.
- Systolic B.P: The normal range of systolic B.P should be 90 – 120 mm Hg.
- Diastolic B.P: The normal range of diastolic B.P should be 60 – 80 mm Hg.
B.P reading is written like this: 120/80. Here it’s read as “120 over 80.” The top number is called the systolic, and the bottom number is called the diastolic. The ranges are:
Normal B.P: Less than 120 over 80 (120/80)
Types of B.P
There are two types of Blood pressure:
- Low B.P: It also called Hypotension. It is the sign of an underlying problem and the blood reading on the sphygmomanometer falls less than 90/60 mm Hg.
- High B.P: It also called Hypertension. It is the sign of an increasing problem, where there is more pressure on blood cells during blood circulation. The blood reading on the sphygmomanometer falls more than 140/90 mm Hg.
