ECMO (extracorporeal membrane oxygenation)

ECMO is a technique that is used in critical patients suffering from very serious respiratory and/or cardiovascular diseases in which conventional life support is not enough. The machine temporarily replaces the function of the lung or heart and allows the organs to rest, while the underlying pathology is healed.

The machine extracts the blood through a thick cannula located in a large vein, moves it through a centrifugal pump into the oxygenator, where oxygen is incorporated and carbon dioxide is removed.

Subsequently, it is reintroduced into the patient’s body through another vein, in which case the strategy is called ECMO VV, veno-venous, and the support offered is respiratory, or through an artery, called ECMO VA, from venoarterial, and the support offered is cardiorespiratory.
