Relationship between continuous distending pressure and transpulmonary pressure or changes in PaO2/FiO2 ratio. Relationship (for each animal) between the continuous distending pressure (CDP) (mbar) and: (a) the transpulmonary pressure (TPP) (mbar) (X, shunt fraction > 10%; +, decrease of the PaO2/FiO2 ratio > 25%), and (b) changes in the PaO2/FiO2 ratio (%) (dotted line, decrease of the PaO2/FiO2 ratio of 25% compared with CDP of 45 mbar (CDP45); X, shunt fraction > 10%).
