What is Blood Pressure & How is it measured? We all know that blood is red in color
which is transmitted to our body . This is red because it has red color pigment called hemoglobin. There are plasma, red blood cells,
white blood cells, and platelets. Blood helps in the formation of oxygen, carbon dioxide and digested foods, etc from body parts to the other parts. It saves us from diseases and also regulates blood temperature. What is Blood Pressure? When the heart beats, it pumps blood around to get the energy and oxygen in the body. As soon as the blood is spread in the body, it pushes against the sides of blood vessels The strength to carry blood vessels leads to pressure which is known as Blood Pressure. Therefore, we can define that blood pressure is the pressure in which blood is pumped around the body by the heart. If the blood pressure is high then extra stress is generated on the arteries or heart and this may also lead to heart attack. Therefore keeping blood pressure normal is very much important. What is normal blood pressure? blood pressure can be reported as two values, such as systolic pressure and diastolic pressure. Now, what are these? The heart pumps the blood and during this process it contracts and spreads. In one stage of heat beat i.e when the heart shrinks and pumps blood into the arteries, it is called systol and when the heart spreads or relaxes in the heart bone and allows chambers to be filled with the blood, is called diastole. Systolic Pressure – 120 mm Hg
Diastolic Pressure – 80 mm Hg Therefore the normal blood pressure is 120/80 but it can vary from time to time and from person to person. Do you know what is High Blood Pressure? High Blood pressure is known as Hypertension. This is due to the contraction of the arteries, which increases the resistance of the blood flow. This can break the arteries and also internal bleeding. It also promotes various health issues. How is Blood Pressure Measured? Blood Pressure is measured by an equipment called as Sphygmomanometer. First of all, the person who is measuring the blood pressure needs to wrap the rubber strap all around his arm then pump the air with a pressure of 200 mm Hg in the brachial artery and the rubber strap increases. Now, you can see this pressure in the machine. At this time when the stethscope was placed on the arm’s artery, no sound was heard. Now, the rubber strap pressure is reduced by deflating and through the stethoscope placed on the artery, the first tapping sound is heard from lease pressure, then it is called systolic pressure. When the rubber lease pressure is reduced by more deflating and through the stethoscope placed on the artery, the tapping sound is heard disappearing through the lease pressure then, this is called as a diastolic pressure. This is how Blood Pressure is been Measured in our body.
