IDVG and Thoracic Fluid Volume

Abstract

In the previous chapter, we demonstrated that initial distribution volume of glucose (IDVG) can consistently indicate the central extracellular fluid (ECF) volume following fluid redistribution from the central to peripheral compartment. Hence, IDVG has potential as a marker for changes in cardiac preload even in the absence of fluid gain or loss. In this chapter, we evaluate the relationship between IDVG and thoracic fluid content (TFC) measured by thoracic electrical bioimpedance (TEB) in thoracic fluid-accumulated patients (Ishihara et al. 2001), and further between IDVG and intrathoracic blood volume (ITBV) (Nakamura et al. 2005; Ishihara et al. 2005b).
