A Sphygmomanometer is a medical device used to measure arterial blood pressure accurately. It typically consists of an inflatable cuff, a measuring unit (mercury, aneroid dial, or digital display), and a pressure-release valve. This essential diagnostic tool is widely used in hospitals, clinics, ambulances, and home-care environments to detect hypertension, hypotension, and other cardiovascular conditions. Modern models provide precise, quick, and non-invasive readings suitable for both human and veterinary applications.

Q1. What is a Sphygmomanometer?

A Sphygmomanometer is a device that measures blood pressure using a cuff and pressure gauge.

Q2. Which types are most accurate?

Mercury Sphygmomanometers (MSM) are the gold standard, but Aneroid (AM) and Digital Blood Pressure Monitors (DBPM) also provide reliable results.

Q3. Can it be used at home?

Yes — digital models are ideal for home BP monitoring.

Q4. Do sphygmomanometers require calibration?

Yes, especially Aneroid Models (AM), which need periodic calibration.

Q5. Is it suitable for animals?

Yes — with the correct cuff size, it is used widely in veterinary practice.
