Figure 1From: Time course of nitric oxide synthases, nitrosative stress, and poly(ADP ribosylation) in an ovine sepsis modelTime changes in (a) pulmonary oxygenation index and (b) pulmonary shunt fraction. Measurements were taken before the sacrifice of animals with sham injury (control) and at different time points after induction of sepsis following acute lung injury. FiO2, fraction of inspired oxygen; PaO2, partial pressure of arterial oxygen. * P < 0.05, ** P < 0.01, *** P < 0.001 vs. control group.Back to article page
