Prompt initiation of cardiopulmonary resuscitation (CPR) is the key to better survival and lower morbidity after a cardiac arrest. Still survival is low even after in hospital cardiac arrest of the order of 20% while it is still lower, of the order of 10% for out of hospital cardiac arrest.
“No flow” time is the period from the onset of cardiac arrest to the initiation of chest compression. “Low flow” time is the period of conventional CPR till the achievement of ROSC (return of spontaneous circulation). Need for prolonged CPR reduces the survival. Need for CPR of 45 minutes or more has been associated with an in hospital survival of less than 2%.
It is in this setting that ECPR or extracorporeal CPR with the help of ECMO (extracorporeal membrane oxygenator) comes in for maintaining better cerebral and vital organ circulation. ECMO also gives rest to the heart allowing chance for recovery if there is a treatable cardiac cause for the cardiac arrest as by coronary revascularization. A study by Patricio D and associates compared ECPR vs conventional CPR.
