Figure 2.

Schematic of (A) venoarterial extracorporeal membrane oxygenation (ECMO), typically used for cardiac failure, and (B) venovenoarterial ECMO, typically used for combined cardiac and respiratory failure, showing common cannulation configurations and direction of blood flow. FSO2 = sweep gas inlet oxygen fraction; VA = venoarterial; Vf-Af = femoral venous drainage to femoral arterial return; Vf-VjAf = femoral venous drainage to jugular venous and femoral arterial return; VVA = venovenoarterial.
