Extracorporeal Membrane Oxygenation in Transport Part 1: Extracorporeal Membrane Oxygenation Configurations and Physiology.

ABSTRACT

Extracorporeal membrane oxygenation (ECMO), a term used to describe oxygenation that occurs outside of the body, is an increasingly common means of supporting the most critically ill patients. Because of the invasiveness and high probability of serious complications during ECMO, ECMO is typically indicated only when there is a high likelihood of death with conventional treatment. With continued improvements in technology and increasing clinical experience, transport clinicians are increasingly likely to be called on to transport patients on ECMO. ECMO can be initiated in 2 distinct forms, venovenous or venoarterial, and can primarily support the respiratory system or the cardiac and respiratory systems concurrently. This review will cover the basic physiology and components of ECMO as well as the preparation for ECMO transport for adults.
