What does manometry mean?
Manometry is the measurement of pressure, particularly the pressure exerted by a liquid or gas. It is especially important in medicine, where pressure readings can be taken in the heart, blood vessels, oesophagus, or other internal structures to help diagnose disorders. A device that performs this measurement is called a manometer. In engineering and laboratory work, manometry can involve comparing an unknown pressure with the pressure of a known reference, such as that of a liquid column. The term is formal and technical rather than everyday, but it describes a fundamental principle used to investigate otherwise invisible physical forces. Accurate manometry can reveal dangerous pressure changes, impaired blood flow, or mechanical obstruction, making it an important diagnostic technique in both clinical and scientific settings.
nounThe measurement of pressure, especially the pressure of a fluid or gas. In medicine, the term commonly refers to the measurement of blood pressure within the cardiovascular system.
- The measurement of pressure in a fluid or gas.
- The medical measurement of blood pressure or pressure within an internal organ.
"Esophageal manometry helped the specialists identify a disorder affecting the patient's swallowing."
"Continuous manometry was used to monitor pressure changes in the artery."
"The laboratory uses manometry to determine the pressure exerted by the gas."
The plural is possible but uncommon; manometry is usually discussed as a process or field rather than counted as a separate entity.
"The two manometries produced readings from different sampling points."
Manometry turns the invisible force of pressure into a measurable value, helping reveal what an ordinary examination cannot see.

Etymology of manometry
Manometry was formed in the 19th century from New Latin, combining elements meaning pressure with the Greek word metron, meaning measure. Its name reflects the systematic measurement of pressure. The related instrument was called a manometer, and the adjectives manometric and manometrically were subsequently derived from the same terminology.

How manometry is actually used
The term is technical and most common in medicine, physics, and engineering. It is more often used for the measurement process than for the device itself.
Easily confused with manometry
Manometry is the process or practice of measuring pressure, whereas a manometer is the instrument used to make that measurement.
