This type of ECMO helps the lungs. Blood is taken from the body, oxygen is added by the ECMO machine, and carbon dioxide is removed, then the blood is returned to the body. The heart continues to perform its normal function.
Veno-Arterial (V-A) ECMO

This type of ECMO helps both the heart and lungs. The ECMO machine adds oxygen, removes carbon dioxide, and assists in pumping blood through the body when the heart needs extra support.
