During venovenous ECMO,what effect does the cardiac output have on oxygenation?

Question

Quizplus · Accepted Answer

VV ECMO does not provide the same level of oxygenation as VA,and the maximal SaO₂ achievable can be as low as 85% until lung function improves.Because VV ECMO is essentially operating in series with the native circulation,alterations in cardiac output will not have a significant effect on oxygenation.The volume of blood removed is equal to the volume reinfused,so there is also no effect on the patient's hemodynamics.
