Task: Answer Verification
Input (English): Question: Is fiberoptic monitoring of central venous oxygen saturation ( PediaSat ) in small children undergoing cardiac surgery : continuous continuous?
Answer:  PediaSat catheters showed unreliable performance in our cohort. It should be further investigated whether repeating calibrations every 8 hours may improve the accuracy of this system. CNIRS may provide similar results with a lower invasiveness.
Output (English): no
