Abstract: measures, in well-defined anatomical regions, the total amount of gas entering in previously nonaerated and poorly aerated regions.Therefore, this method roughly measures the same entity of the lung mechanics-based methods.In conclusion, if the target is the measurement of the amount of pulmonary units, which likely undergo opening and closing at PEEP below 15 cm H 2 O, the only method available is the computed tomography scan at threshold 2100 HU (2200 HU could be tolerated).In contrast, if the target is the measurement of the total improvement of aeration, resulting from gas entering in the previously nonaerated regions and in the already aerated regions, the Rouby's method and lung mechanics-based methods are indicated.Therefore, the problem is not whether one method is better than the other but rather what we want to measure.
