Figure 2

Cytokine response. A blood sample was obtained from the radial artery catheter during three interventions, normoxia (FIO2 = 21%), hyperoxia (FIO2 = 40%) and hypoxia (FIO2 = 12%), at baseline, and after a four-hour lipopolysaccharide (LPS) infusion in healthy volunteers (n = 10). A: Plasma TNF-α; B: Plasma IL-6. Data are presented as median (black line), interquartile range (IQR, box) and total range (whiskers). Different from normoxia in the same condition (baseline/LPS), ** P<0.01. Different from the same intervention (normoxia/hyperoxia/hypoxia) at baseline, †† P<0.001.
