Placing a pregnant patient on her left side is crucial for preventing uterine compression, particularly if she is in her third trimester. When a pregnant woman lies on her back, the weight of the uterus can compress major blood vessels, notably the inferior vena cava, which can lead to reduced blood flow back to the heart. This can potentially result in hypotension and decreased perfusion to both the mother and the fetus.

Lying on the left side helps to alleviate this pressure. The position allows for optimal blood flow and circulation, making it the recommended position for pregnant patients in many emergency situations. This position is also beneficial in enhancing fetal oxygenation and minimizing the risk of complications during transport or medical intervention.

Although other positions, such as sitting up or lying on the right side, might be considered, they do not provide the same level of safety in preventing uterine compression and promoting adequate blood flow. Thus, the left lateral position is the preferred choice to safeguard both maternal and fetal well-being.
