Which device is primarily used to monitor blood pressure?

• A. Sphygmomanometer
• B. Stethoscope
• C. Electrocardiogram (ECG)
• D. Pulse oximeter

Answer: (A)

The sphygmomanometer is the device specifically designed to measure blood pressure. It works by inflating a cuff around the patient's arm, temporarily stopping the flow of blood. As the cuff deflates, the healthcare professional listens to the sounds of blood as it begins to flow again—this is where the systolic and diastolic blood pressure readings are obtained. This device is integral in assessing the cardiovascular health of patients, as blood pressure readings provide crucial information regarding the heart's function and overall circulatory system performance. The other devices mentioned serve different purposes: the stethoscope is primarily for listening to internal sounds of the body, the electrocardiogram (ECG) monitors electrical activity of the heart, and the pulse oximeter measures oxygen saturation in the blood, none of which directly monitor blood pressure.
