Question

CPR is in progress on a pregnant woman. Shortly after manually displacing her uterus to the left, return of spontaneous circulation occurs. Which of the following would MOST likely explain this?- Displacement of her uterus allowed her lungs to expand more fully, which restored her pulse.- Increased blood flow to her heart caused her ventricles to stop fibrillating, which restored her pulse.- Displacement of her uterus caused blood to flow backward, which increased blood flow to her heart.- Pressure was relieved from her aorta and vena cava, which improved chest compression effectiveness.

Answer 1

Answer:

pressure was relieved from her aorta and vena cava, which improved chest compression effectiveness.
