Tensiometriaa

Tensiometriaa is not a widely established term in standard reference works. It is commonly a misspelling or variant of tensiometría, a word used in different fields to describe the measurement of tension. In general, tensiometry can refer to either the measurement of surface or interfacial tension in liquids, or to the measurement of arterial blood pressure in medical contexts.

In chemistry and physics, tensiometry is the practice of quantifying surface or interfacial tension. Instruments and methods include the Du Noüy ring method, the Wilhelmy plate method, pendant-drop tensiometry, and capillary rise techniques. Measurements are typically expressed in units of milliNewtons per meter (mN/m). Water at room temperature has a surface tension around 72–73 mN/m. Tensiometry is used to study surfactants, oils, polymers, emulsions, foams, and coatings, as well as in quality control for food, cosmetics, pharmaceuticals, and materials science.

In a medical setting, tensiometry is sometimes used to refer to the measurement of blood pressure. This is typically performed with a sphygmomanometer and stethoscope (auscultatory method) or with automated oscillometric devices. Results are given as systolic over diastolic pressure (for example, 120/80 mmHg). Blood-pressure tensiometry is essential for diagnosing and monitoring hypertension and other cardiovascular conditions.

Terminology can vary by region and discipline; when in doubt, the context usually clarifies whether tensiometry refers to surface tension measurements in liquids or to blood pressure assessments.
