1. Maintain blood flow to the lungs.
2. Open the patent foramen ovale.
3. Increase blood flow to the extremities.
4. Decrease resistance of blood flow through the heart.

Feedback
1. The prostaglandin will allow the Patent Ductus Arteriosis to have patency.
2. The patent foramen ovale is already open when a Tetrology of Fallot is present.
3. Blood flow to the heart and lungs rather than the extremities is the priority.
4. Because of the holes in the heart, the resistance is already low.
