Task: Answer Verification
Input (English): Question: Does central venous oxygen saturation correlate with the venous oxygen saturation at the surgical site during abdominal surgery?
Answer: Our results show a lack of correlation between central venous oxygen saturations and oxygen saturations in the draining veins of the surgical site during major abdominal surgery. Measurement of central venous oxygen saturations does not seem to be a good surrogate for the local oxygen supply in the field of interest in major abdominal surgery even under standardized conditions.
Output (English): no
