A sphygmomanometer is also known as a mercury pressure device. It works by a mechanical manometer made of mercury that measures the pressure.
The device that Torricelli invented for measuring air pressure is called a barometer. It works by balancing the weight of the atmosphere with the weight of a column of mercury in a glass tube.
The device used to measure air pressure is called a barometer. It can be either an aneroid barometer or a mercury barometer, both of which are commonly used to measure atmospheric pressure.
A mercury barometer measures atmospheric pressure, which is the weight of the air pressing down on Earth's surface. It works by using a column of mercury in a sealed tube to balance the pressure of the air outside. When the air pressure increases, the mercury in the tube rises, and when the air pressure decreases, the mercury falls.
Suction is typically measured using a device called a manometer, which compares the pressure of the suction with atmospheric pressure. The difference in pressure is then quantified in units such as inches of mercury (inHg) or millimeters of mercury (mmHg). Alternatively, vacuum gauges can also be used to measure suction.

Torricelli invented a device for measuring air pressure called a mercury barometer. It consists of a glass tube filled with mercury placed in a dish of mercury. The height of the mercury in the tube changes with variations in atmospheric pressure.

A mercury barometer is a device used to measure atmospheric pressure. It consists of a glass tube filled with mercury, with one end submerged in a mercury bath. Changes in atmospheric pressure cause the level of mercury in the tube to rise or fall, which can be used to determine the current pressure readings.
Evangelista Torricelli is known for his invention of the barometer in 1643. His original device consisted of a long tube of glass (which contained a vacuum) on top of a larger container of mercury. The pressure from air pressing down onto the exposed surface of the mercury would push the mercury upwards into the tube; thus, the higher the air pressure, the higher the mercury level. Air pressure was then measured using "millimeters of mercury", which corresponded to the mercury level within the tube.

Both the can in the pan of water and the mercury barometer function based on the principle of atmospheric pressure. In both cases, changes in atmospheric pressure will cause a corresponding change in the level of water or mercury in the device. The height of the water or mercury serves as an indicator of the atmospheric pressure at that moment.

Your blood pressure can be taken with a mercury blood pressure gauge, an aneroid manometer, or an electronic device for measuring the blood pressure, as long as the device has been recently calibrated and validated. With rare exceptions, blood pressure gauges found in supermarkets or pharmacies aren't properly maintained and shouldn't be used.

The difference in pressure is then quantified in units such as inches of mercury (inHg) or millimeters of mercury (mmHg). Alternatively, vacuum gauges can also be used to measure suction.

A barometer measures atmospheric pressure by using a column of mercury to indicate changes in pressure. As air pressure changes, it moves the mercury up or down in a tube. This movement is then converted into a numerical value representing the atmospheric pressure.
Pressure is measured in mercury because mercury is a dense liquid that is sensitive to changes in pressure. When pressure is applied, the height of the mercury in a column changes, allowing for accurate measurement of pressure levels.
