What is the recommended position for a pregnant patient in respiratory distress?

The recommended position for a pregnant patient in respiratory distress is the left lateral position. This position is beneficial for several reasons.

First, during pregnancy, especially in the later trimesters, the weight of the uterus can compress the inferior vena cava when a patient is lying supine. This can hinder venous return to the heart, potentially contributing to decreased cardiac output and exacerbating respiratory distress.

By positioning the patient in the left lateral position, you can help mitigate the pressure on the inferior vena cava, allowing for better blood flow to the heart. Additionally, this position can enhance oxygenation by improving lung mechanics and facilitating diaphragmatic movement. The left lateral position is particularly recommended as it optimally supports both maternal and fetal circulation.

While sitting straight up might seem appropriate for alleviating respiratory distress, it may not address the specific physiological challenges faced by a pregnant patient. Similarly, the right lateral position, although better than supine, does not offer the same benefits as the left lateral position concerning venous return and uteroplacental blood flow.
