Figure 3From: Adjusting tidal volume to stress index in an open lung condition optimizes ventilation and prevents overdistension in an experimental model of lung injury and reduced chest wall compliance Computed tomography scan and distribution of the ventilation. Left side: Ventral ROI, right side: Dorsal ROI. SI-group: VT adjusted to SI between 0.95 and 1.05. Pplat-group: VT adjusted to Pplat = 30 cmH2O. Level 1: aortic arch, level 2: heart, level 3: main bronchi and level 4: just above the diaphragm. HU: Hounsfield units. ROIs, regions of interest.Back to article page
