The total body impedance measured from the SOZO unit correlated with PAD with a correlation coefficient of 0.876. The findings from this case suggest that BIS may provide an additional noninvasive tool to detect extracellular fluid excess and impending congestion before hospitalization. BIS correlates well with diastolic PA pressures and may prove a useful adjunct in the management of HF. Further research is needed in a larger more diverse group of patients to assess the role BIS plays in the management of HF.
