[Volume kinetics--a new method to control intravenous fluid infusion]

The body's handling of fluid given by intravenous infusion can be analysed and simulated by means of volume kinetics, in which pharmacokinetic principles are applied to dilution-time profiles obtained during fluid therapy. In volume kinetics, the emphasis is on the distribution of fluid to body fluid spaces which accordingly become expanded. These spaces do not always correspond to known anatomical or physiological fluid compartments. The time course of the effect of volume fluid distribution to these spaces may be investigated by means of computer-assisted simulation, or a nomogram based on values for volume kinetic variables obtained from infusion experiments.
