BIA involves passing a very weak electrical current through the body to measure its resistance to the current. Aim. Thus, techniques that provide valid assessments among individuals of varying levels of body fatness are critical to evaluate intervention outcomes. Bioelectrical impedance vector analysis (BIVA) overcomes these limitations because it only uses determinations of resistance (R) and reactance (Xc) normalized for height and yields a vector of specific magnitude (length) and direction (phase angle). We prospectively analyzed bioelectrical impedance in 145 children aged between one month and six years who were not in septic shock on admission to the intensive care unit Serial bioelectrical impedance analysis (BIA) measures were analyzed to determine the sensitivity and specificity of accurately identifying children who subsequently developed septic shock.

A small current is used to measure the resistance at difference frequencies against the various tissues in the body eg fat/lipid has a high resistance to the flow of current, therefore shows a high impedance reading. The comparative value with other biomarkers remains to be elucidated. Changes in cell permeability have been observed early in sepsis.
