Hypothesis
How does recirculation affect oxygen delivery in veno-venous ECMO?
Conclusion
Recirculation significantly reduces the amount of oxygenated blood delivered to patients on veno-venous ECMO, leading to refractory hypoxemia.
Supporting Evidence
- Recirculation can significantly reduce extracorporeal oxygen delivery.
- Quantifying recirculation is essential for optimizing VV-ECMO lung support.
- Interventions and ECMO configurations can potentially reduce recirculation.
Takeaway
When blood is pumped through a machine to help people breathe, some of it can go back into the machine instead of the body, which is not good because it means less oxygen gets to the patient.
Methodology
This review synthesizes existing literature on recirculation in veno-venous ECMO, focusing on methods to calculate and reduce recirculation.
Limitations
There are limited data on the effectiveness and safety of interventions to reduce recirculation.
