From: Cannulation configuration and recirculation in venovenous extracorporeal membrane oxygenation

(A) Recirculation fraction (\({R}_{f})\) under femoro-atrial venovenous extracorporeal membrane oxygenation (VV ECMO) with occluded and patent side-holes in the drainage cannula and for a range of decreased inferior vena cava (IVC) inflows (75β0%, 2.9β0 L/min). Occ.β=βoccluded side-holes, SVCβ=βsuperior vena cava. (B) \({R}_{f}\) under atrio-femoral VV ECMO for three drainage cannula positions: baseline at junction of SVC and right atrium, mid SVC and distal SVC.
