A method to adapt thoracic impedance based on chest geometry and composition to assess congestion in heart failure patients

Highlights • We examined simulations and measurements of thoracic impedance for different chests. • Chest geometry and composition has a non-linear impact on measured thoracic impedance. • We describe a method to adjust for this to provide expected dry impedance and fluid index. • Fluid indices were...

Summary:Highlights • We examined simulations and measurements of thoracic impedance for different chests. • Chest geometry and composition has a non-linear impact on measured thoracic impedance. • We describe a method to adjust for this to provide expected dry impedance and fluid index. • Fluid indices were high in heart failure patients admitted for acute heart failure. • In particular symptoms associated with pulmonary congestion increased the index.
