Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate the feasibility of using electric impedance tomography (EIT) to monitor lung perfusion during veno-venous (VV) extracopreal membrane oxygenation (ECMO) support, as well as the effect of different ECMO flows on lung perfusion monitored by EIT.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a monocentric obsevensional study that uses EIT to monitor lung perfusion during VV ECMO support and the effect of different ECMO flows on lung perfusion as measured by EIT. Patients on VV ECMO who meet the withdrawal criteria as determined by clinical experts will have their ECMO flow gradually reduced. EIT lung ventilation and perfusion monitoring were performed at various ECMO flows.
