Nisshi pShygmomanometer, also known as ablood pressure meter,blood pressure monitor, orblood pressure gauge, is a device used to measureblood pressure, composed of an inflatablecuffto collapse and then release the artery under the cuff in a controlled manner and amercuryor mechanicalmanometerto 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 astethoscope.
A sphygmomanometer consists of an inflatable cuff, a measuring unit (themercury manometer, or aneroid gauge), and a mechanism for inflation which may be a manually operated bulb and valve or a pump operated electrically.
- Measurement accuray: +/- 3 mmHg
- The lower value on the scale is “0”, the aneroid pointer in the “0” position must be within a tolerance of +/- 3 mmHg
listening to the internal sounds of an animal or human body. It typically has a small disc-shaped resonator that is placed against the skin, and one or two tubes connected to two earpieces. A stethoscope can be used to listen to the sounds made by theheart, lungs orintestines, as well as blood flow inarteriesandveins. In combination with a manualsphygmomanometer, it is commonly used when measuringblood pressure.
