Expert Solution

Step 1: Introduction to blood pressure measurement

Blood pressure is defined as the pressure exerted by the flow of blood on the walls of the arteries while flowing through them.
Blood pressure is measured through a device known as spigmomanometer.
The brachial artery of upper limb is usually chosen to measure blood pressure.
An inflatable cuff wraps around the cubital fossa. A stethoscope is placed on the brachial artery that passes through the cubital fossa.
The cuff is inflated and then deflated slowly.
When deflating the first sound that appears through the stethoscope is the systolic blood pressure.
While deflating further the sound again disappears and then appears again. This is diastolic blood pressure.
The sounds heard during auscultation while measuring blood pressure are known as the korotkoff sounds.
