Electrical impedance tomography [PDF]

open access: yesAnnals of Translational Medicine, 2018
Continuous assessment of respiratory status is one of the cornerstones of modern intensive care unit (ICU) monitoring systems. Electrical impedance tomography (EIT), although with some constraints, may play the lead as a new diagnostic and guiding tool for an adequate optimization of mechanical ventilation in critically ill patients.

Limitations of Electric Impedance Plethysmography [PDF]

open access: yesCirculation Research, 1954
Electric impedance plethysmography has been offered as a substitute for mechanical plethysmography and would be particularly suitable for regions in which the mechanical method cannot be applied. A comparative investigation of mechanical and impedance plethysmograms, taken simultaneously from a finger or a forearm, revealed that, while the normal ...

Ventilation inhomogeneity in patients with cystic fibrosis measured by electrical impedance tomography [PDF]

open access: yes, 2012
Objective: The distribution of ventilation within the lung is inhomogeneous. We hypothesized that the degree of inhomogeneity in patients with cystic fibrosis (CF) differs from that in healthy subjects.
