Q

Extracorpeal membrane oxygenation

A

ECMO - supports hypoxemia without the potentially injurious ventilator setting sometimes needed in severe ARDS

“a treatment that uses a pump to circulate blood through an artificial lung back into the bloodstream… provides heart-lung bypass support outside of the body”
