Which type of sphygmomanometer is the most accurate?
Mercury sphygmanometer
How often should a mercury sphygmomanometer be calibrated?
every month
How does a mercury pressure device work?
A sphygmomanometer is also known as a mercury pressure device. It works by a mechanical manometer made of mercury that measures the pressure.
What are the types of sphygmomanometer?
The 3 types are: Manual, Digital and Aneroid.
What are the different parts of a blood pressure apparatus?
The three types of blood pressure machines are Automatic Sphygmomanometer, Aneroid Sphygmomanometer, and Mercury Sphygmomanometer. The automatic performs automatic functions such as cuff inflation and sophisticated readings. The aneroid consists of a metal bellows that expands on account of increased pressure so the amplifier effects the indicator needle. The mercury is dependent upon the other blood pressure machines for accuracy and calibration.
What are the parts of the sphygmomanometer?
There is a clear tube where the mercury column is that contains mercury that rises in the tube to read pressure. The rubber tube connected to the reservoir goes to the blood pressure cuff. There is a rubber bulb to fill the cuff and a valve for releasing the air.
Why Mercury is used in spygmomanometer?
Mercury is a heavy, silvery-white metal.Due to the high density of mercury a rise in small column of mercury can exert much pressure. so it is used to measure pressure as a small tube is sufficient to measure a considerable pressure.More over Mercury does not stick to the glass surface inside
What is the measurement used to measure blood pressure called?
mm Hg (milimeters of mercury) usually measured with a Stethoscope and a sphygmomanometer .
Why is a mercury type of sphygmomanometer called a gold standard?
because it is less likely to produce inaccurate readings than the electronic versions.
What is a sphygmonometer?
Sphygmomanometer (the correct spelling).A Sphygmomanometer is an instrument used to measure an individuals indirect blood pressure. They generally consist of an inflatable cuff that fits around a limb (normally the arm, just above the elbow), a bulb for controlling air pressure within the cuff, and a mercury or aneroid manometer (a dial stating the pressure in millimeters of mercury, mmHg).
How does digital blood pressure monitor works?

If water was used in a sphygmomanometer instead of mercury what would be the systolic and diastolic blood pressure?
Mercury's density is around 13.54 x that of water, so the pressures (in mm of water) would be 13.54 x what they are for mercury - 100 mm Hg would be around 1354 mm H2O
