Sphygmomanometers
A sphygmomanometer or blood pressure meter is a device used to measure blood pressure, comprising of an inflatable cuff to restrict blood flow, and a mercury or mechanical manometer to measure the pressure. It is always used in conjunction with a means to determine at what pressure blood flow is just starting, and at what pressure it is unimpeded. Manual sphygmomanometers are used in conjunction with a stethoscope. A sphygmomanometer usually consists of an inflatable cuff, a measuring unit (the mercury manometer), a tube to connect the two, and (in models that don't inflate automatically) an inflation bulb also connected by a tube to the cuff. The inflation bulb contains a one-way valve to prevent accidental leak of pressure while there is an adjustable screw valve for the operator to allow the pressure in the system to drop in a controlled manner.
Types of Sphygmomanometers are:-
Digital - manual or automatic inflation. These are electronic, easy to operate
Digital portable finger blood pressure monitors - with automatic inflation. These are more portable and easy to operate, though less accurate. They are the smallest blood pressure monitors
Manual – They are operated by a trained person. Mercury manometers are considered to be the "gold standard" of measurement because their measurement is absolute and does not require re-calibration
