ECMO
Pronunciation: EK-moh
Also written as: ECMO — Extracorporeal Membrane Oxygenation
Extracorporeal membrane oxygenation providing temporary mechanical circulatory support outside the body.
Full Definition
Extracorporeal membrane oxygenation is a life support technique that uses a modified heart-lung bypass machine to provide cardiac and/or respiratory support for patients with severe heart or lung failure. In cardiovascular surgery, ECMO can serve as a bridge to recovery, transplantation, or other interventions. The system pumps blood from the patient's body to an artificial lung (oxygenator) that removes carbon dioxide and adds oxygen, then returns the blood to the patient.
Usage
Usage note: Always capitalize all letters. Distinguish from CPB (cardiopulmonary bypass) which is used during surgery.
