Electrical impedance tomography vs whole thoracic impedance for monitoring lung fluid content in congestive heart failure patients

Detection of pulmonary edema is possible with the bio-impedance technique. In the present study two approaches, the whole-thoracic impedance and the Electrical Impedance Tomography, for monitoring pulmonary congestion level were compared. A good correlation ratio of R=0.75 (p-value<;0.01) was found between the two data sets. The results suggest that the EIT method with 8 electrodes has the potential to be used for monitoring patients with congestive heart failure.
