What is an important step to take for a pregnant patient in cardiac arrest to perform CPR effectively?

Ensuring high-quality chest compressions is crucial when performing CPR on a pregnant patient in cardiac arrest. High-quality chest compressions are vital for maintaining blood circulation to both the mother and the fetus. The goal during CPR is to provide adequate blood flow to critical organs, and in the case of a pregnant patient, this includes both the mother's heart and the fetus.

During chest compressions, it’s important to take into account the anatomical and physiological changes that occur during pregnancy. This can include the weight of the uterus pressing on major blood vessels, which can impede blood flow. Therefore, positioning the patient appropriately, such as tilting her on her left side, can help alleviate pressure on the aorta and enhance blood flow. The emphasis on high-quality compressions—maintaining proper depth, rate, and allowing full chest recoil—ensures the most effective circulation during this critical time.

While other steps such as activating advanced life support teams, using fetal monitors, or administering oxygen are also important in the overall management of a cardiac arrest emergency, the immediate priority is to ensure that chest compressions are performed correctly and effectively, as this directly influences survival chances in both the mother and the fetus.
