Chest x-rays of patients with common venovenous extracorporeal membrane oxygenation cannulation strategies. Red arrows represent return sites of oxygenated blood to the patient. Blue arrows represent drainage of venous blood from the patient. (A) Femoral–right internal jugular cannulation. (B) Dual-lumen right internal jugular cannulation with Avalon Elite cannula. (C) Femoral–femoral cannulation with return cannula at the junction of the inferior vena cava (IVC) and right atrium and drainage in the IVC. (D) Femoral–femoral cannulation with the return cannula in the right atrium. The drainage cannula (not pictured) is in the femoral vein or distal IVC.
