Focus Area: Sphygmomanometer                                                         


A sphygmomanometer (pronounced /ˌsfɪɡmoʊməˈnɒmɨtər/ SFIG-moh-mə-NOM-i-tər) or blood pressure meter is a device used to measure blood pressure, comprising 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.

The word comes from the Greek sphygmós (pulse), plus the scientific term manometer (pressure meter). The device was invented by Samuel Siegfried Karl Ritter von Basch in 1881.[1] Scipione Riva-Rocci introduced a more easily used version in 1896. Harvey Cushing discovered this device in 1901 and popularized it.

A sphygmomanometer consists of an inflatable cuff, a measuring unit (the mercury manometer, or aneroid gauge), and inflation bulb and valve, for manual instruments.

Sphygmomanometer comes in 3 types.

1. Mercury manometers

2. Aneroid (Dial Types)

3. Digital/Electronic. (Click for special Series on Omron)
