Figure 2From: Low tidal volume pressure support versus controlled ventilation in early experimental sepsis in pigsQuotient of PaO 2 and FiO 2 (PaO 2 /FiO 2 ). Group effects over time are analyzed by two-way-ANOVA and post-hoc Holm-Sidak procedure. n.s. = non-significant, PSV: pressure support ventilation, VCV: volume-controlled ventilation.Back to article page
