Background

ECMO is an english abbreviation for extracorporeal membrane oxygenation (extracorporeal membrane oxygenation), which is a technology representing the critical emergency level in a hospital, even a region, a country. In 1953 Gibbon had an epoch-making significance for extracorporeal circulation performed by cardiac surgery. Not only can the cardiac surgery develop rapidly, but also a new chapter can be written for the emergency department. During cardiac surgery, extracorporeal circulation may completely replace the heart and lung for a short period of time, while open heart surgery may be performed. Meanwhile, the rescue success rate after extracorporeal circulation quickly established in the heart surgery room is very high. The students immediately had the idea of converting this technology into a technology that supports rescue. But the implementation is not optimistic and a series of problems are difficult to solve, and ECMO is an extracorporeal circulation technology which leaves a heart operating room. The principle is that the venous blood in the body is led out of the body, and is injected into the artery or vein system of a patient after being oxygenated by an artificial cardiopulmonary bypass made of special materials, so that the function of partial cardiopulmonary replacement is achieved, and the oxygenation blood supply of the visceral organs and tissues of the human body is maintained.
