Manual Blood Pressure Monitor - How It Works & Usage Guide #3005157 (License: Personal Use)

This illustration shows a manual sphygmomanometer featuring a squeezable rubber bulb, inflatable cuff, coiled tubing, and an analog pressure gauge with a needle dial. The device operates by inflating the cuff to occlude arterial flow, then gradually releasing pressure while listening for Korotkoff sounds with a stethoscope. It remains a gold standard in many medical environments due to its reliability and lack of battery dependence.

Used on medical education pages, hypertension awareness resources, and equipment comparison guides; targets patients, students, and clinicians seeking foundational knowledge about blood pressure measurement tools.
