Cardiac physiology is to collect de-oxygenated blood, in the right atrium, from the body via the superior vena cava, inferior vena cava and from the coronary sinus and pump it, through the tricuspid valve, via the right ventricle, through the semilunar pulmonary valve and into the pulmonary artery in the pulmonary circulation where carbon dioxide can be exchanged for oxygen in the lungs. This happens through the passive process of diffusion. In the "left heart" oxygenated blood is returned to the left atrium via the pulmonary vein. It is then pumped into the left ventricle through the bicuspid valve and into the
Congenital diaphragmatic hernia baby will usually be immediately placed on a ventilator. Extracorporeal membrane oxygenation (ECMO) has been used as part of the treatment strategy at some hospitals. ECMO acts as a baby heart-lung bypass (though it can be used for older children as well). A venous cannula is inserted into the jugular vein or the common femoral vein(ECMO is divided into two types; (arteriovenous AV and venovenous VV), allowing the blood to exit the body and begin its trek through the ECMO circuit, it is then scrubbed, oxygenated, and passes through a filter before being returned to the body via a second
