Excerpt

Electrical impedance tomography has become a tool for monitoring regional ventilation. Interest is growing to derive additional information on pulmonary perfusion and ventilation/perfusion distribution. Since signals recorded by electrical impedance tomography also contain cardiac-related impedance changes, attempts are made to evaluate them in view of perfusion. Recently in Critical Care a corresponding study applying an advanced filtering technique for separating cardiac signals from the dominant ventilation component was published [1]. The quality of the concept is demonstrated by comparing the results with solitary cardiac signals during breath-hold. …
