Veno-Veno (VV) ecmo is most often used for patients with severe lung dysfunction as in the case of ARDS, H1N1, and Cystic Fibrosis as a bridge to lung transplant.
-
Typically these patients will be on maxed ventilator support with inhaled nitric oxide or inhaled epoprostenol and still have poor oxygenation.
-
VV has the capability to provide the support for the failing lungs.
-
We must remember that VV ecmo only supports the lungs and the patient must have good native cardiac function.
-
There are 2 common routes for VV ecmo cannulation, both are considered peripheral cannulation.
-
The first one uses a dual lumen catheter tube inserted into the internal jugular vein and and the second option uses two catheters placed in the femoral vein and the internal jugular vein.
Duel Lumen
Peripheral Cannulation
Common issues with VV ecmo:
-
Recirculation- is when oxygenated blood bypass the heart and lungs and gets pulled back into the ecmo machine.
