[Compartment analysis of potassium metabolism--mathematical modelling of 42-K tracer kinetics].

The possibility of application of the theoretical concept of the compartment analysis in the modelling of the potassium balance was demonstrated. A use of the compartment analysis of the potassium balance in the clinical routine diagnostics in the sense of a highly specialised functional diagnostics seems according to recent experiences reasonable only in closest cooperation with clinicians. The diagnostics and the control of therapy of the chronic syndrome of potassium deficit as well as metabolically conditioned disturbances of the distribution of potassium were to be seen as possible indication. At the same time the establishment of reference values for the demarcation of relative disturbances of distribution as well as for the establishment of the normal region of the turnover rates were necessary.
