A obstruction type differential pressure or variable area. Unfortunately some bromine 82 also distributes into the cells. What are the various body fluid compartments and their percentage water distribution. The common types of flowmeters with industrial applications are listed below. Total body water is 60 of body weight and is divided into various body fluid compartments. If you measure too soon all you will get is the volume of the functional extracellular fluid.
Rapid mixing of tritiated water throughout all compartments occurs during a 3 to 4 hour equilibration period. 222 total body water. Flow measurement is the quantification of bulk fluid movement. Often these fluids are tested instead of blood because they can give more direct answers to what may be going on in a particular part of the body. Some body fluids that may be tested include. Thus bromine measurements of the ecf volume frequently over estimate the ecf volume.
Types of body fluid testing laboratory testing can be performed on many types of fluids from the body other than blood. This is estimated by measuring the volume of distribution of isotopes of water. Theoretically its possible to measure the size of each of the body fluid compartments by injecting substances that will stay in one compartment only the substance that attach to object that. Tritium oxide tho is used because it is a weak beta emitter making it easy to measure in a liquid scintillation counter. Flow can be measured in a variety of ways. Measuring the extracellular fluid volume with crystalloid tracer.
