Background
Extracorporeal Membrane Oxygenation (ECMO) is a medical emergency treatment device used for extracorporeal respiration and circulation of patients during cardiopulmonary surgery, and can be applied to treatment of patients with severe infectious diseases such as new coronary pneumonia, and operations such as severe cardiopulmonary failure and heart transplantation. Besides the heart and lung function of the patient can be temporarily replaced, the load of the heart and lung of the patient is relieved, and more treatment time can be won for medical personnel.
The ECMO is characterized in that venous blood in vivo is led out of a human body, is oxygenated by an artificial cardiopulmonary bypass made of special materials and then is injected into an artery or vein system of a patient, so that a partial cardiopulmonary replacement effect is achieved, and the oxygenation blood supply of human organ tissues is maintained. In ECMO operation, blood is drawn from the vein and passes through the membrane lungs to absorb oxygen and remove carbon dioxide. When the lung function of a patient is seriously damaged and the conventional treatment is ineffective, ECMO can undertake the gas exchange task, so that the lung is in a rest state, and precious time is won for the rehabilitation of the patient. Also, when the cardiac function of the patient is seriously damaged, the blood pump can replace the cardiac pumping function to maintain the blood circulation.
