True statements about veno-venous ECMO include:
a) Injury to right common carotid artery may necessitate reconstruction
b) Oxygen saturation measured in the pulmonary artery will be lower than normal due to severe lung disease
c) Expected aortic oxygen saturation varies from 75-95%
d) None of the above
Click for Answer
Answer
Answer c. Veno-venous ECMO does not involve carotid or other arterial cannulation. PA saturation will be higher than normal due to increased SvO2 with infusion of highly oxygenated blood into the venous system. During V-V ECMO, systemic SpO2 is usually 75-95%.
