1a and b – Arterial Oxygenation and Respiratory System Compliance. Arterial oxygen tension (PaO₂) over time for the 3 groups (BVV in red; CMV in blue and CMV-RM in green) (a). The group × time interaction is p = 0.0001. No difference is seen between groups at baseline and following oleic acid infusion. By 2 hr the PaO₂ is greater with BVV (+). There is no difference between CMV and CMV-RM. Respiratory system compliance over time for the 3 groups (b). The group × time interaction is p = 0.089. Least squares means tests revealed BVV had significantly greater compliance after 2 hr (+). There was no difference between CMV and CMV-RM.
