Fig. 2. Relative pulmonary blood flow (Q̇^rel) distribution versus  the dorsal-to-ventral axis in one representative animal from each group. The numbers of pieces per lung were 236 for the control animal and 233 for the treatment animal, respectively. The slopes remained unchanged in treatment animals, whereas the slopes became more negative over time in control animals showing that Q̇^relwas redistributed from dependent (ventral) to nondependent (dorsal) lung areas. CTL = control group; PFX = treatment group; t^inj= established injury; t³⁰= 30 min after established injury; t⁶⁰= 60 min after established injury; t¹²⁰= 120 min after established injury.
