Assessment of readiness for venoarterial extracorporeal membrane oxygenation (VA ECMO) weaning relies on hemodynamic and metabolic parameters of cardiac and respiratory functions. Lactate clearance, inotropic support, and echocardiographic criteria, such as left ventricular ejection fraction, aortic valve opening, and ventricular function, are key to assessing myocardial recovery. Although structured protocols exist for the preoperative stage, intraoperative weaning remains highly variable and poorly standardized.¹
