ecmo a few hundred thousand to a few million ranging, Extracorporeal Membrane Oxygenation (Extracorporeal Membrane Oxygenation, ECMO), commonly known as the "Yek Membrane", "Artificial Lungs", is a medical emergency technology equipment, mainly used to provide continuous extracorporeal respiration and circulation for patients with severe cardiopulmonary failure in order to maintain the patient's life. ECMO, commonly known as "Yeke Membrane" and "Artificial Lung", is a medical emergency technology device mainly used to provide continuous extracorporeal respiration and circulation to patients with severe cardiorespiratory failure in order to maintain the patients' lives.
The basic structure of ECMO: endovascular cannula, connecting tube, power pump (artificial heart), oxygenator (artificial lung), oxygen supply tube, monitoring system. Clinically, the disposable part is often formed into a sleeve, and the non-disposable part is bound and stored, and designed to be movable to improve the emergency response capability.
Power pump (artificial heart): the role is to create power to drive the blood to the side of the tube, similar to the function of the heart. There are two main types of power pumps in the clinic: roller pumps, centrifugal pumps. Because the roller pump is not easy to move, management is difficult. Centrifugal pumps are preferred as power pumps in emergency medicine. The advantage is that the installation is easy to move, easy to manage, blood damage is small; in a reasonable range of negative pressure has a pumping effect, can solve the problem of low flow caused by certain reasons; a new generation of centrifugal pumps for pediatric low flow is also easy to manipulate.
