Non-invasive Measurement of Central Hemodynamics by Electrical Impedance Tomography

Non-invasive Measurement of Central Hemodynamics and Heart-lung Interactions by Electrical Impedance Tomography

The purpose of this study is to evaluate the ability to measure central hemodynamics and heart-lung interactions non-invasively by electrical impedance tomography and compare it to clinically established hemodynamic monitoring.
