Figure 2

Global lung ventilation. (a) Relationship of global lung ventilation measured with electrical impedance tomography (VTEIT predicted) and positron emission tomography (VPET) in the first part of the experiment. The regression line was drawn over all experimental points pertaining to both normal (open circles) and acute lung injury (closed circles) conditions. (b) Relationship of the difference to the mean of global lung ventilation measured with electrical impedance tomography (VTEIT predicted) and positron emission tomography (VPET) in the first part of the experiment. Horizontal continuous line and horizontal broken lines are the mean and the upper (mean + 2 standard deviations) and lower (mean - 2 standard deviations) values of the difference, respectively.
