Hemofiltration

Part of speech: noun

Definitions

  1. A medical procedure that removes waste and excess fluids from the blood by filtering it outside the body through a semipermeable membrane ; a technique used in critical care to support kidney function by continuously cleansing the blood of toxins and fluids ; a treatment method involving extracorporeal blood purification aimed at managing renal failure by eliminating harmful substances and regulating fluid balance
  2. An extracorporeal process that filters blood through a membrane to extract waste, fluids, and toxins ; a continuous renal replacement therapy that helps maintain electrolyte balance and remove excess fluids in patients with kidney failure ; a clinical technique designed to mimic kidney function by removing metabolic waste products and maintaining fluid homeostasis via blood filtration
  3. A therapeutic intervention for kidney dysfunction in which blood is passed through a filter to remove impurities and excess water ; a method of continuous blood purification using a membrane-based filtration system to manage fluid overload and toxin accumulation ; a renal support treatment that involves filtering the blood externally to maintain chemical and fluid equilibrium in critically ill individuals

Etymology: Hemofiltration is a blood-cleaning treatment in which blood is drawn from the body, passed through a filter that removes waste and excess fluid, and returned. It is built from two parts that are both easy to trace. The first, "hemo-", comes from Greek "haima", meaning blood, and it appears in many medical terms such as hemoglobin and hemorrhage. The second, "filtration", comes from the Latin "filtrare", to filter, which itself derives from "filtrum", a felt cloth used for straining liquids. The word is a straightforward compound made by joining the blood prefix to the familiar process noun, so its meaning can be read directly from its parts. Its modern sense is specific: the treatment works by filtration alone, without the chemical dialysis process that takes its name from a separate Greek root, which is why the two terms are often contrasted in kidney care.

Synonyms: blood filtration, renal replacement therapy
