Pascal
Pascal (medicine)
Pascal (/pæˈskæl/, French: [paskal]) is a unit of pressure used in medicine, named after the French mathematician, physicist, and philosopher Blaise Pascal.
Etymology
The term "Pascal" is derived from the name of Blaise Pascal, a renowned French mathematician, physicist, and philosopher. Pascal made significant contributions to the field of fluid dynamics and pressure, which led to the naming of the unit of pressure after him.
Definition
In medicine, a Pascal (Pa) is the SI unit of pressure used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. It is defined as one newton per square meter. It is a measure of force per unit area, expressed in terms of Newtons per square meter (N/m²).
Related Terms
- Pressure: The force applied perpendicular to the surface of an object per unit area.
- SI unit: The international system of units, which is the modern form of the metric system.
- Newton: The SI unit of force, named after Sir Isaac Newton.
- Young's modulus: A measure of the stiffness of a solid material.
- Ultimate tensile strength: The maximum stress that a material can withstand while being stretched or pulled before breaking.
Usage in Medicine
In the medical field, the Pascal unit is often used in the context of blood pressure, intracranial pressure, and the pressure exerted by various medical devices such as ventilators. It is also used in biomedical research to measure the mechanical properties of tissues and biomaterials.
