What is ECMO?
Extra Corporeal Membrane Oxygenation
Blood is drained from the venous system Oxygenated through an artificial lung,
removing carbon dioxide Returned to the patient
![Page 3: Jason Lippy, RN Paula Minor, RN University of Maryland Medical Center March 2012.](https://reader035.fdocuments.us/reader035/viewer/2022062713/56649cef5503460f949bd14b/html5/thumbnails/3.jpg)
Goal of ECMO
Ensure oxygen supply meets/exceeds the patient’s demands
Prevent end organ dysfunction and tissue death.
Rest heart and/or lungs Allow time for healing

Venovenous (VV) ECMO Blood is drained FROM and returned TO the
venous circulation Does NOT provide hemodynamic support Goal is to rest the lungs Allow time for healing
![Page 7: Jason Lippy, RN Paula Minor, RN University of Maryland Medical Center March 2012.](https://reader035.fdocuments.us/reader035/viewer/2022062713/56649cef5503460f949bd14b/html5/thumbnails/7.jpg)
Venoarterial (VA) ECMO Provides pulmonary and hemodynamic
support Heart and lungs are bypassed Venous/drainage and arterial/return Nonpulsatile

Single Site Cannulation
One double lumen catheter is inserted through the right IJ into the right atrium
Blood is drained and returned through separate lumens in the same cannula
