ALERT
Performing cardiopulmonary resuscitation (CPR) on a pregnant patient in the supine position poses an additional risk because the gravid uterus compresses the ascending vena cava, which impairs venous return and reduces cardiac output. All attempts at resuscitation will be futile unless the compression is relieved. Uterine displacement—achieved either by displacing the uterus manually or by placing the patient in an inclined lateral position through the use of a wedge—is crucial.3
The resuscitation team leader should activate the protocol for an emergency cesarean delivery as soon as cardiac arrest is identified.
