Regarding mixed venous oxygen saturations, which one
of the following statements is CORRECT?
a) In septic shock, SvO2 is unlikely to be normal or supranormal
b) With a ventricular septal defect, a reduction in
SvO2will be observed
c) If oxygen flux is fixed, elevated oxygen
consumption results in increased SvO2
d) If arterial oxygen saturation, haemoglobin and
oxygen consumption are constant,
SvO2 varies directly with cardiac
output
e) Cyanide toxicity causes a reduction in SvO2
