The centrifugal pump takes blood from the femoral vein (continuous blue line) and ejects it into the thoracic aorta (TA) (continuous red line). In the triple cannulation VV-A ECMO, the pump takes blood from femoral vein (continuous blue line) and LV (dashed lilac line), respectively and ejects it into the thoracic aorta (continuous red line). In the triple cannulation VA-A ECMO, the pump takes blood from FV (continuous blue line) and LA (dashed blue line), respectively and ejects it into the TA (continuous red line).
