Extracorporeal life support (ECLS) is a temporary mechanical assistance method employed in acute respiratory, cardiocirculatory, and cardio-respiratory failure, refractory to conventional treatments. Patient's hemodynamic, respiratory and metabolic condition, or situations related to ECLS support or performance, may change during ECLS treatment. Provision of an additional drainage or perfusion cannula, or even of an additional associated device, for example, transaortic suction device or intra-aortic balloon pump (IABP), may be required to improve the ECLS/patient interaction and effects. ⋯ The PA allows the institution of a multitasking ECLS circuit, ranging from enhanced left ventricle (LV) unloading (drainage from the PA) to a right ventricular support or "central" veno-venous ECLS (perfusing the PA), tailored according to the patient hemodynamic, gas exchange, metabolic state, underlying cardiac involvement, and ECLS performance. Dynamic ECLS may, therefore, represent an additional option in ECLS management, particularly including the PA cannulation. Based on this new dynamic management of ECLS mode, we propose the Extracorporeal Life Support Organization nomenclature update.
