Q: Question: Does use of the trendelenburg position in the porcine model improve carotid flow during cardiopulmonary resuscitation?
Answer: The Trendelenburg position can lead to increased blood flow through the carotid arteries during CPR in this pig model. Future studies should investigate whether this increased blood flow through the carotid arteries leads to improved brain perfusion and better neurologic outcomes.
A:
yes
