Venovenous (VV) Extracorporeal Membrane Oxygenation (ECMO) is a specialized treatment that provides respiratory support to children whose lungs are severely damaged or failing. It involves circulating blood through an external oxygenator, which removes carbon dioxide and adds oxygen before returning the blood to the body. Unlike venoarterial (VA) ECMO, which supports both heart and lung function, VV ECMO is strictly for respiratory support.
