Fetal pH, blood gases and metabolites during late recovery after sham occlusion (control, n = 7) or HI (n = 7) induced by umbilical cord occlusion. , arterial pressure of carbon dioxide; , arterial pressure of oxygen; Hct, haematocrit; O2ct; arterial oxygen content. Data are the mean ± SD. Statistical analysis comprised ANOVA with group as the independent factor and time as repeated measure. Significant effects of group are shown in bold.
