Introduction

Blood pressure is the force of blood against the walls of arteries as the heart pumps it around the body. Blood pressure readings consist of two numbers: systolic and diastolic. Systolic pressure represents the force when the heart beats, while diastolic pressure represents the force when the heart rests between beats. High blood pressure can damage blood vessels, increase the risk of heart disease, stroke, and other health problems.

How Does Blood Pressure Measurement Work?

Blood pressure measurement involves the use of a cuff, a gauge, and a stethoscope. The cuff wraps around the upper arm and inflates to restrict blood flow. The gauge indicates the pressure applied, and the stethoscope helps to listen for the sound of blood returning to the artery. The cuff gradually deflates, and the blood flow resumes. The first sound heard marks the systolic pressure, and the last sound marks the diastolic pressure.

Types of Blood Pressure Cuffs
