transfusion
The process of transferring blood or other blood products from one person or animal into the bloodstream of another. / The transfer of a quality, idea, or energy from one person, group, or entity to another to revitalize or change it. / The act of transferring a liquid, such as a chemical or nutrient solution, from one container or vessel to another.
Noun
pl: transfusions
In medical contexts, this term is highly technical and describes a life-saving procedure. It carries a connotation of urgency and precision, often associated with emergency care or chronic illness. It is distinct from "infusion," which typically refers to the slow introduction of a fluid or medication into the body rather than the replacement of blood.
When used figuratively, the word suggests a desperate need for revitalization. It implies that the recipient is depleted or failing and requires an external "injection" of resources—such as money, talent, or energy—to survive. This usage is common in business and political discourse to describe a sudden, transformative influx of support.
