extracellular fluid volume


Also found in: Acronyms.

ex·tra·cel·lu·lar flu·id vol·ume (ECFV),

the fraction of body water not in cells, about 20% of body weight; it consists of plasma water (about 4% of body weight), water between cells (interstitial water-lymph, about 15% of body weight), and water in dense bone and connective tissue (about 1% of body weight).
See also: intracellular fluid.

Both are stimulated by reduced extracellular fluid volume sensed by high pressure baroreceptors located in the aortic arch and carotid sinus which relay information to the brainstem via the glossopharyngeal and vagal nerves and from the brainstem to the hypothalamus by ascending noradrenergic pathways.

Using bioimpedance analysis, we measured extracellular fluid volume changes on individuals with transtibial amputation while they ambulated with either elevated vacuum sockets, suction sockets, or sockets with lock-and-pin suspension.
Acute renal failure is a syndrome that is best described as a decline in renal function resulting in a disturbance of electrolyte and acid-base homeostasis, derangement of extracellular fluid volume, and retention of nitrogenous wastes from protein catabolism (Brady, Brenner, & Lieberthal, 1996).
