How Blood Pressure Is Measured: Sphygmomanometer Diagram Explained #2147493 (License: Personal Use)

The image displays a side-by-side schematic of a sphygmomanometer in use on a patient’s upper arm, with the cuff inflated to two different pressures: 120 mmHg and 150 mmHg. Each panel shows the cuff wrapped around the arm, connected to a bulb for inflation and a gauge indicating pressure, while a stethoscope is positioned over the brachial artery to detect Korotkoff sounds. The shaded zigzag patterns inside the cuff represent turbulent blood flow during auscultation.

Used in medical education, clinical training materials, or health information websites to explain manual blood pressure measurement technique; matches user intent to understand how systolic and diastolic values are determined during physical exams.
