Sphygmomanometer

Sphygmomanometer: Sphygmomanometer is an instrument used to measure the blood pressure at the bedside. Till date most sphygmomanometers used a mercury column to measure the pressure. But aneroid sphygmomanometers are being used more often now because of the environmental issues associated with the use of mercury. Sphygmomanometer is more commonly known as BP apparatus (BP: blood pressure).
