A blood pressure machine is a medical device used to measure the pressure of blood in the arteries. It helps doctors and patients monitor heart health easily. The machine usually has a cuff that wraps around the arm. When the cuff inflates, it measures the pressure of blood flow. It shows two readings: systolic (high pressure) and diastolic (low pressure). Some machines are manual with a stethoscope, while others are digital and easy to use at home. Digital machines display results on a screen within seconds. Regular checking with this device helps prevent heart diseases. It is an important tool for maintaining a healthy lifestyle.
