How can team members maximize the effectiveness of chest compressions for a 32-year-old patient at 30 weeks' gestation who goes into cardiac arrest?

The choice of positioning the patient in the supine position with manual left uterine displacement is optimal for maximizing the effectiveness of chest compressions in a 32-year-old patient who is 30 weeks pregnant and experiences cardiac arrest.

During pregnancy, especially in the later stages, the growing uterus can exert pressure on the inferior vena cava when the patient is in a supine position. This pressure can compromise venous return to the heart, leading to decreased cardiac output, inadequate perfusion, and reduced effectiveness of chest compressions. By performing manual left uterine displacement, which involves tilting the uterus to the left, it alleviates this pressure. This position enhances venous return, thereby improving hemodynamics during chest compressions and increasing the likelihood of achieving successful resuscitation.

In contrast, placing the patient in the Trendelenburg position can be problematic since it does not address the compression of major blood vessels and can actually worsen blood flow in a pregnant woman. The left lateral position might provide some benefit by shifting the weight off major vessels, but it is not as effective as the combination of being supine with left uterine displacement, especially during cardiopulmonary resuscitation (CPR). Lastly, lifting the patient to a sitting
