Task: Answer Verification
Input (English): Question: Is central venous saturation an alternative to mixed venous saturation during cardiopulmonary bypass in coronary artery surgery patients?
Answer: Although mean biases between the measurements were low, limits of agreement were too large to provide a clinically acceptable estimation of SvO(2) by ScvO(2) in these conditions. Variations in regional oxygen consumption seem to be the main factor worsening the relationship.
Output (English): no
