How to Use a Manual Sphygmomanometer - Blood Pressure Measurement Guide #3577705 (License: Personal Use)

This illustration shows a manual sphygmomanometer featuring a vertical mercury column calibrated from 0 to 200 mmHg, a gray inflatable cuff connected via tubing, and a rubber bulb with valve for inflation. The device operates on the auscultatory method using a stethoscope (not shown) to detect Korotkoff sounds during deflation. Though largely replaced by digital devices in primary care, mercury sphygmomanometers remain a gold standard in calibration and high-accuracy settings.
