Extracorporeal membrane oxygenation ECMOalso known as extracorporeal life support ECLSis an extracorporeal technique of providing prolonged cardiac and respiratory support to persons whose heart and lungs are unable to provide an adequate amount of gas exchange or perfusion to sustain life. The technology for ECMO is largely derived from cardiopulmonary bypasswhich provides shorter-term support with arrested native circulation. This intervention has mostly been used on children, but it is seeing more use in adults with cardiac and respiratory failure.

The application of extracorporeal life support ECLS to adults with respiratory failure, although more recent and less well established than neonatal ECLS, is undergoing continuing development and refinement. Consequently, criteria for the selection of adult patients for ECLS are also less well established. Although the adult experience is perhaps too small to subject to critical evaluation, selection criteria applied by adult ECLS centers are fairly uniform and predict substantial mortality with conventional therapy based on historical data.

Extracorporeal membrane oxygenation ECMO is the use of a modified heart—lung machine to provide respiratory, circulatory, or both support at the bedside, usually for at least a number of days or even weeks. ECMO is a valuable option for the management of severe but reversible causes of respiratory failure or cardiogenic shock refractory to conventional treatment. Acute respiratory distress syndrome associated with pneumonia viral or bacterial is the most common cause of refractory hypoxaemia that requires ECMO support.

Its use has increased markedly in the last decade, initially in response to severe Acute Respiratory Distress Syndrome ARDS in adults during the H1N1 influenza epidemic and continuing with the increasing acceptance of Extracorporeal Membrane Oxygenation ECMO for the treatment of severe respiratory failure in adults from other causes. Patients in the conventional ventilation group were allowed to crossover into the ECMO group at the discretion of the treating physicians, which made it difficult to draw definitive conclusions regarding the benefit of early ECMO. The trial investigators believed that not allowing crossover would be unethical, despite recognizing the potential difficulty it would cause in analyzing the data. There was a statistically significant benefit of ECMO in regards the secondary end-point of treatment failure, which was defined as death in the ECMO group and either death or crossover to ECMO in the conventional ventilation group.

Although we're far from the development of a Darth Vader-esque life support system, ECMO or extracorporeal membrane oxygenation has come a long way in recent years. Although initially a means of therapy used to help newborn babies, an increasing number of adults are receiving ECMO, and ECMO centers are popping up all over the world. Although nearly half of these cases involve neonates with respiratory problems, a combined 10, cases involve adults with respiratory and cardiac problems or in need of pulmonary resuscitation.

Extracorporeal membrane oxygenation ECMO is a way to provide breathing and heart support. ECMO can provide necessary oxygenation to an infant while doctors treat the underlying condition. Older children and adults may also benefit from ECMO under certain circumstances.

Nirmal S. ECMO is now being used in acute respiratory distress syndrome and was used extensively for this indication during the influenza H1N1 pandemicas a bridge to lung or heart transplant, and in postcardiac arrest patients. We review the current evidence and indications for ECMO, focusing on its principles and practical aspects in adult patients with respiratory or cardiac failure.

Extracorporeal membrane oxygenation ECMO for severe acute respiratory distress syndrome ARDS has known a growing interest over the last decades with promising results during the A H1N1 influenza epidemic. Targeting populations that can most benefit from this therapy is now of major importance. However, ECMO is still marred by frequent and significant complications such as bleeding and nosocomial infections. Because this therapy is costly and exposes patients to significant complications, seven prediction models have been developed recently to help clinicians identify patients most likely to survive once ECMO has been initiated and to facilitate appropriate comparison of risk-adjusted outcomes between centres and over time.

Advances in mechanical circulation have resulted in improvements in both survival and quality of life for an increasing number of patients with advanced heart failure. Prompt identification and resuscitation of patients has a marked impact on improving outcomes. However, this modality requires a higher level of care and traditionally has remained underutilized.

But for adults, the odds of surviving depend on which hospital provides the life-supporting treatment — with the best odds at ones that use the technique dozens of times a year, a new study finds. Researchers at the University of Michigan Medical School looked at data from 56, patients treated at hospitals around the world over 25 years.
