Maximizing cardiac output in labor for ischemic heart disease centers on improving venous return and avoiding compression of major vessels by the uterus. The lateral position, particularly the left side, relieves the uterus’ pressure on the inferior vena cava, increasing venous return to the heart, which raises stroke volume and overall cardiac output. This helps meet myocardial oxygen needs during contractions and reduces ischemia risk. Standing decreases venous return from gravity, lying supine can cause aortocaval compression, and Trendelenburg isn’t well tolerated in pregnancy. So the lateral position best supports maternal hemodynamics during labor.
