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.

Using limb circumference and voltage electrode separation measurements in an accepted geometric model, we converted the data to extracellular fluid volume [26].
In this study, we defined "residual-limb fluid volume change" as the extracellular fluid volume change measured using the multifrequency bioimpedance analysis system.
We then converted the data to extracellular fluid volume using the limb-circumference and segment-length measurements in a well accepted geometric limb model [24], and then expressed it as a percentage of the extracellular fluid volume measured at the end of the initial 2 min sit interval with the prosthesis donned.
Residual limb extracellular fluid volume was measured with use of bioimpedance analysis.
In this article, only extracellular fluid volume data are presented.
