When administering CPR to a pregnant patient, how should you position her?

Positioning a pregnant patient correctly during CPR is crucial for both the mother and the fetus. When a pregnant woman is in the supine position (lying flat on her back), the growing uterus can exert pressure on the inferior vena cava, the large vein that carries deoxygenated blood from the lower body back to the heart. This pressure can reduce blood return to the heart, which may lead to decreased cardiac output and compromised blood flow to the fetus.

By positioning the pregnant patient on her side, specifically the left side, you relieve pressure on the inferior vena cava. This position enhances venous return and optimizes circulation, allowing for more effective cardiac compressions. It also helps to prevent the potential complications associated with supine hypotensive syndrome, which can arise in advanced stages of pregnancy.

Other positions, like sitting upright or lying flat without adjustments, do not address the concern of venous return and can hinder the effectiveness of CPR. Elevating the legs while lying flat may also not be appropriate, as it does not alleviate the compression on the inferior vena cava. Thus, the correct positioning is essential to ensure that both the mother and fetus receive adequate oxygenation and support during a cardiac emergency.
