Which is the primary reason for slightly tilting a pregnant patient to the left on a backboard?

The main concept is that in late pregnancy the enlarged uterus can press on the inferior vena cava when a patient is lying flat, which reduces venous return to the heart and lowers uteroplacental blood flow. Tilting slightly to the left relieves this compression, restoring venous return and increasing cardiac output, which in turn improves uteroplacental perfusion and fetal oxygen delivery. This is why the primary reason for a left tilt is to enhance venous return and uteroplacental perfusion. While other reasons like airway protection or reducing airway pressure can be considerations in different scenarios, they are not the primary driver for this repositioning in this context.
