Blood pressure is the pressure of our blood on the walls of the blood vessels. This pressure is generated by the amount of blood the heart pumps and the resistance of the blood vessels. Usually, it is expressed as systolic pressure over diastolic pressure. Normal adult blood pressure is about 120/80 mmHg. An adequate blood pressure is crucial to sustaining the perfusion of vital organs.
Blood pressure can be measured by a non-invasive method such as a mercury-tube sphygmomanometer with a stethoscope. A cuff will be wrapped around your arm and the doctor will inflate the cuff and auscultate with the stethoscope to listen to the sounds which mark the systolic and diastolic pressure.
A low blood pressure is called hypotension while abnormal high blood pressure is called hypertension. Hypertension is so prevalent worldwide. WHO estimated that around 40% of global population with raised blood pressure. In the year 2017, the American Heart Association revised the definition of hypertension. Normal blood pressure is defined as <120/<80 mm Hg. Systolic blood pressure of 130-139 or diastolic blood pressure of 80-89 mm Hg will be defined as stage 1 hypertension already in the new definition. Hypertension will adversely affect our health. People suffering from hypertension will have increased risk of having coronary heart disease and stroke.
