Correct Answer:
Option D —
Sphygmomanometer
A sphygmomanometer (pronounced sfig-mo-ma-nom-eter) is the standard medical device used to measure blood pressure. It typically consists of an inflatable rubber cuff that is wrapped around the arm, a measuring unit (mercury manometer or digital display), and a bulb to inflate the cuff.
How it Works When the cuff is inflated, it temporarily stops the blood flow in the artery. As the air is slowly released, a healthcare professional uses a stethoscope to listen to the sounds of blood flow (called Korotkoff sounds).Systolic Pressure: The pressure when the heart beats (the first sound heard).Diastolic Pressure: The pressure when the heart rests between beats (when the sound disappears).
Normal Reading: Typically around 120/80 mmHg.
