Overview

In extracorporeal membrane oxygenation (ECMO), blood is pumped outside of your body to a heart-lung machine that removes carbon dioxide and sends oxygen-filled blood back to tissues in the body. Blood flows from the right side of the heart to the membrane oxygenator in the heart-lung machine, and then is rewarmed and sent back to the body.

This method allows the blood to "bypass" the heart and lungs, allowing these organs to rest and heal.

ECMO is used in critical care situations, when your heart and lungs need help so that you can heal. It may be used in care for COVID-19, ARDS and other infections.
