How Blood Pressure is Measured?
Hypertension is a term used to describe high blood pressure. There are different reasons why a person can suffer from high blood pressure. Blood pressure is measured on the scale of millimeters of mercury.
Mercury being the most sophisticated liquid present, detects the changes easily. The mean value of systolic pressure and diastolic pressure is the measured value of BP. Any change in the value of these pressures suggests either increase in blood pressure or a decrease in blood pressure.
According to a survey carried out by health organizations, people who are exposed to high stress levels are often found to develop high blood pressure.
Normal systolic pressure is usually considered to have value of 120 mm Hg. This is considered to be the value at which blood pressure is under control. Usually when the heart pumps blood into the arteries, there is pressure building up at the entrance of the arteries until the blood flows into the veins.
When the pressure is higher than normal, the heart starts to work harder to deliver the blood more effectively through the arteries. This will increase the stress of the heart and the blood vessels and may lead to a heart attack.
Normal diastolic pressure has a value of 80 mm Hg. When the value is below this particular number, a person experiences low blood pressure. A person with low blood pressure is often found to experience dizziness, light-headedness and fainting at frequent intervals.
Under this condition, the blood circulation is not reaching the organs effectively through the arteries. Standing up is a problem as it can cause dizziness when one has low blood pressure.
Usually a healthy person who does not experience low blood pressure does not have problems with standing up as the blood vessels present in the heart prevent dizziness. This ensures that there is a smooth flow of blood throughout the arteries.
Doctors use a blood pressure measuring machine to note down the value of the blood pressure of a person. This helps them diagnose the ailments which the person may have due to changes in the blood pressure and in the blood circulation.
Arteries generally experience a pressure when there is a flow of blood from the heart. Any change in the pressure will lead to high or low blood pressure depending on the person's overall health condition. Hence, it is very important for a person to reduce their stress levels and follow a healthy diet to overcome high blood pressure.
