Task: Answer Verification
Input (English): Question: Does volume expansion alter cerebral tissue oxygen extraction in preterm infants with clinical signs of poor perfusion?
Answer: Cerebral perfusion, as assessed by cFTOE, does not improve in preterm infants with signs of poor perfusion following volume expansion. In these infants, either CAR is present or volume expansion is inadequate to affect cFTOE.
Output (English): no
