Changes in oxygenation variables in sheep. Data are expressed as mean ± standard error of the mean. *P < 0.05, LPS versus sham-operated group; ^†P < 0.05, OA versus sham-operated group; ^‡P < 0.05, LPS versus OA group; ^§P < 0.05, versus t = 0 hours in LPS group; ^llP < 0.05, versus t = 0 hours in OA group. DO₂I = oxygen delivery index; LPS = lipopolysaccharide; OA = oleic acid; Qs/Qt = venous admixture; SaO₂ = arterial oxygen saturation; Sham = sham-operated; SvO₂ = venous oxygen saturation.
