Risk of cerebral hypoxia with ECMO
Venoarterial extracorporeal membrane oxygenator (ECMO) is a potential lifesaving intervention in those with refractory cardiogenic shock. But there is potential risk of cerebral hypoxia because of upper body hypoxemia. Upper body is perfused by the left ventricular output which can be hypoxemic if there is pulmonary edema. Lower body is perfused with oxygenated blood from the ECMO .
