Figure 4. Weaning of percutaneous ECMO.

CVP = central venous pressure; ECMO = extracorporeal membrane oxygenation; LVEF = left ventricular ejection fraction; LVOT = left ventricular outflow tract; MAP = mean arterial pressure; MCS = mechanical circulatory support; SFA = superficial femoral artery; SvO₂ = mixed venous oxygen saturation; S’ = tissue Doppler tricuspid lateral peak systolic velocity; PAOD = peripheral arterial occlusive disease; RV = right ventricular; VTI = velocity time integral.

*Low level of vasopressor/inotropes refers to norepinephrine ≤0.03 μg/min/kg and dobutamine ≤5 μg/min/kg.
