Which instrument is used for noninvasive measurement of blood pressure?

Explanation:
Measuring blood pressure without penetrating the skin is done with a cuff-based device that inflates to occlude the arm and then yields a pressure reading—the sphygmomanometer. It’s designed to determine systolic and diastolic pressures noninvasively, often used with a stethoscope for auscultation during measurement. Other instruments have different uses: a glucometer checks blood glucose, an ophthalmoscope examines the inside of the eye, and an otoscope looks into the ear. Therefore, the sphygmomanometer is the instrument used for noninvasive blood pressure measurement.
