FIGURE 7. Relationships between preset minute-ventilation and alveolar ventilation (VA_emission, A) or specific ventilation (A_emission/VA_emission, B) assessed with PET in control pigs (•) and pigs with lung injury (). For each pig, VA_emission and A_emission/VA_emission were measured regionally using modeling in each ROI. Regional values of VA_emission were summed to obtain global ventilation expressed as mean ± SD for each experimental group (A). Median values of regional A_emission/VA_emission were calculated for each animal and data were finally expressed as mean ± SD for each experimental group (B). Bars are SDs. Solid and dotted lines are regression lines for control and oleic acid groups, respectively.
