The force that is exerted by the circulation of blood in the blood vessels is referred to as the blood pressure. The pressure is reduced once the blood flows through the arteries as well as veins, and the arterial pressure can be measured using a sphygmomanometer. The sphygmomanometer basically comprises of three types, namely, the aneroid, mercury and the digital variety.

Most often, in hospitals, nurses make use of hot-air balloon blood pressure cuff and determine the pressure directly by placing the gauge directly on an artery. The cuff is made use for application of pressure on the arteries, and it is puffed up so that the blood flow is blocked and the air is gradually let off.
