Fig. 5From: Roles of neurally adjusted ventilatory assist in improving gas exchange in a severe acute respiratory distress syndrome patient after weaning from extracorporeal membrane oxygenation: a case reportCenter of ventilation (COV) in each lung calculated by electrical impedance tomography. Figure shows values during flow trigger (FT, right) and NAVA (left). The sum of ventilation-related impedance change in each lung slice is calculated and presented as a bar in the histograms. Horizontal lines indicate the position of COV. COV shifted to the dorsal region during NAVA in the right lung.
