Body composition analysis lends itself to a number of modeling techniques. Choose any one or more of the following models depending upon the specific needs of your patients.
Two-Compartment Mass Model
The two-compartment mass model divides the body into Fat-Free Mass and Fat
Mass. This simple model is useful when evaluating basic nutritional, fitness,
and weight management needs of patients.
Three-Compartment Mass Model
The three-compartment mass model divides the body into Body Cell Mass,
Extracellular Mass, and Fat Mass. This model is often used in support of nutritional counseling and monitoring changes associated with aging. This model is also certainly appropriate for the full range of patients.
One-Compartment Water Model
The one-compartment water model accounts for Total Body Water (TBW). Total
Body Water is the sum of Intracellular Water and Extracellular Water and is
wholly contained within Fat-Free Mass. Normally, about 73% of Fat-Free Mass
is water. This simple model is handy for evaluating basic hydration
status of patients.
Two-Compartment Water Model
The two-compartment water model divides Total Body Water into Intracellular Water and Extracellular Water. This model is often used for the assessment of fluid balance associated with the treatment of conditions in a clinical setting.
Five-Compartment Model
For a comprehensive picture of fluid and tissue compartments, the five-compartment model divides the body into Metabolic Tissue, Intracellular Water, Extracellular Water, Bone Tissue, and Fat Mass.
