The development of extracorporeal membrane oxygenation

Abstract

Evolving from the development of heart-lung machines for open-heart surgery, extracorporeal membrane oxygenation has reemerged as a rescue modality for patients with acute respiratory failure that cannot be supported by conventional modes of ventilation. The history of extracorporeal membrane oxygenation begins with the discovery of heparin, fundamental to the success of extracorporeal circulation and membrane lungs. Engineers and scientists created suitable artificial membranes that allowed gas exchange while keeping gas and blood phases separate. Special pumps circulated blood through the devices and into patients without damage to delicate red cells and denaturing plasma. Initial attempts in adults ended in failure, but Robert Bartlett, first at Loma Linda, CA, then at Ann Arbor, MI, succeeded in applying the technology in newborn infants with persistent pulmonary hypertension. Preserved in the critical care of infants, the technology in time could be reapplied in the life support of older children and adults.
