In the field of medicine and physiology, mm Hg stands for millimeters of mercury, a unit used to measure pressure. This unit is commonly used to measure blood pressure, atmospheric pressure, and pressure in various medical equipment.
What is mm Hg?
Millimeters of mercury (mm Hg) is a unit of pressure that is based on the pressure exerted by a column of mercury of one millimeter in height at the standard acceleration of gravity. It is often used as a unit of pressure in medical settings, particularly when measuring blood pressure.
Measuring Blood Pressure
When blood pressure is measured, it is typically expressed as two numbers, such as 120/80 mm Hg. The first number represents the systolic pressure, which is the pressure in the arteries when the heart muscle contracts. The second number represents the diastolic pressure, which is the pressure in the arteries when the heart is at rest between beats.
Other Uses of mm Hg
Aside from measuring blood pressure, mm Hg is also commonly used to measure atmospheric pressure. Standard atmospheric pressure at sea level is approximately 760 mm Hg. In addition, mm Hg is used in devices such as barometers and manometers to measure pressure in various systems.
In conclusion, millimeters of mercury (mm Hg) is an important unit of pressure used in various applications, including the measurement of blood pressure and atmospheric pressure. Understanding this unit is crucial in the fields of medicine, meteorology, and engineering.
