How the Professional Mercury Sphygmomanometer works

A Professional Mercury Sphygmomanometer is a medical device used to measure blood pressure. It consists of a cuff that is placed around the upper arm, a pump to inflate the cuff, and a mercury manometer for measuring blood pressure. This type of sphygmomanometer is often used by healthcare professionals due to its accuracy and reliability. However, due to safety concerns related to mercury, digital sphygmomanometers have become more commonly used in recent years.

A Professional Mercury Sphygmomanometer with a working principle based on a mercury sphygmomanometer is called the Professional Mercury Sphygmomanometer. It is made up of a cuff, a pressure gauge, and a balloon that must be manually inflated.

A manual inflation ball fills the cuff with air while it is wrapped around the patient's arm in the measurement position. The air pressure around the cuff is now measured by the pressure gauge. The doctor or nurse will then gradually remove the gas from the cuff while monitoring how far the mercury in the manometer drops before the patient's pulse can be heard.

This procedure actually compares the internal blood pressure in the arteries to the exterior pressure the arm cuff is exerting on the arm of the patient. The mercury column descends vertically, allowing us to calculate the blood pressure. Mercury must be used and handled carefully because it is a heavy metal. The Professional Mercury Sphygmomanometer still has some clinical utility despite the fact that the majority of contemporary blood pressure monitors have digital displays.
