Perfuzj

Perfuzj is a term occasionally found in informal Polish-language writing as an abbreviated form of perfuzja, or perfusion in English. In formal medical and biological literature, perfuzja denotes the movement of a fluid through a network of vessels or through tissue, enabling delivery of oxygen, nutrients, medications, and the removal of waste.

Contexts for perfusion include in vivo systemic perfusion, referring to the circulation of blood or infused fluids throughout the body, and ex vivo or tissue perfusion, which involves circulating a perfusate through an isolated organ or tissue for preservation, testing, or research. Perfuzja is essential in organ transplantation, where machine perfusion can keep organs viable before implantation, as well as in reconstructive surgery, cancer therapy, and tissue engineering.

Methods and measurement of perfusion involve parameters such as flow rate, pressure, and oxygen delivery. Imaging and monitoring techniques include CT perfusion, MR perfusion, ultrasound-based methods, and laser Doppler flowmetry. Experimental approaches utilize isolated organ perfusion devices and various perfusates, including blood, crystalloids, or specialized solutions.

Usage and terminology: The term perfuzj is not standard in formal scientific publications; it typically appears as a shorthand or in colloquial contexts. When precision is required, perfuzja or perfusion is preferred.
