Figure 6. Norepinephrine doses and systemic vascular resistance index had significantly different outcomes in animals treated with IABC vs. no pump at low bacterial dose, low lethality challenges (left panel) compared to high bacterial dose, high lethality challenges (right panel) of S. aureus (p = 0.002 interaction, Panel A; p < 0.0001 interaction, Panel C).

Figure 6

During high dose bacterial challenges, the IABC (solid circle, solid line) compared to no pump (open circle, dashed line) significantly lowered the dose of norepinephrine required and systemic vascular resistance index obtained, but this was not true at low dose bacterial challenges. There was no significant difference for CI and PvO2 between the effect of the IABC versus no pump comparing low to high dose bacterial challenges (all, p = ns for an interaction, Panel B and D).
