Measurement of lung function using Electrical Impedance Tomography (EIT) during mechanical ventilation

Measurement of lung function using Electrical Impedance Tomography (EIT) during mechanical ventilation

The consistency of regional lung density measurements as estimated by Electrical Impedance Tomography (EIT), in eleven patients supported by a mechanical ventilator, was validated to verify the feasibility of its use in intensive care medicine. There were significant differences in regional lung densities between the normal lung and diseased lungs associated with pneumonia, atelectasis and pleu...

Electrical Impedance Tomography During Mechanical Ventilation.

Electrical impedance tomography (EIT) is a noninvasive, non-radiologic imaging modality that may be useful for the quantification of lung disorders and titration of mechanical ventilation. The principle of operation is based on changes in electrical conductivity that occur as a function of changes in lung volume during ventilation. EIT offers potentially important benefits over standard imaging...

Assessment of Regional Ventilation Distribution: Comparison of Vibration Response Imaging (VRI) with Electrical Impedance Tomography (EIT)

BACKGROUND Vibration response imaging (VRI) is a bedside technology to monitor ventilation by detecting lung sound vibrations. It is currently unknown whether VRI is able to accurately monitor the local distribution of ventilation within the lungs. We therefore compared VRI to electrical impedance tomography (EIT), an established technique used for the assessment of regional ventilation. METH...

Mechanical ventilation guided by electrical impedance tomography in experimental acute lung injury.

OBJECTIVE To utilize real-time electrical impedance tomography to guide lung protective ventilation in an animal model of acute respiratory distress syndrome. DESIGN Prospective animal study. SETTING Animal research center. SUBJECTS Twelve Yorkshire swine (15 kg). INTERVENTIONS Lung injury was induced with saline lavage and augmented using large tidal volumes. The control group (n = 6) ...
