20150921 fluid compartments regulation of ecf volume fluid replacement duration. All exchanges of water and solutes with the external environment occur through the extracellular fluid ecf eg intravenous infusion and intake or loss via the gastrointestinal tract. Compartment volumes are measured by determining the volume of distribution of a tracer substance. At 60 years of age you if male only have 50 body water instead of 60. A method has been developed by which body fluid volume changes can be assessed frequently after only one initial injection of the appropriate radioactive tracers. This volume is regulated by the movement of free water.

Extracellular fluid 27 189 litres. Body fluids can be discussed in terms of their specific fluid compartment a location that is largely separate from another compartment by some form of a physical barrier. Fluid physiology 22 measurement of compartment volumes. Measuring the extracellular fluid volume with ionic tracer. The tracer is the patients own red cells which are tagged with radio chromium cr 51 red cellstypically a 10 ml sample of the subjects blood is incubated with a sodium chromate solution the label is taken up by the red cells and any excess in the solution is removed by dilution and centrifuging with removal of fluid.
