Summary
Our hypothesis is that there will be a decrease in internal jugular venous flow in the park bench position when compared to the supine position. There will also be a change in blood flow in the between right and left internal jugular veins in park bench position, particularly there will be a greater reduction of flow on the dependent side. However, the internal jugular venous flow will be the same in both the prone and supine position.
