DictionarySeechainchain of survival
A sequence of steps proposed by the American Heart Association for managing early cardiac arrest. The chain would begin with CPR of a victim at the scene by trained laypersons, and would be passed on to emergency medical services upon their arrivalchain of sur·vi·val (chān sŭr-vī'văl) The American Heart Association's term for four major interventions designed to reduce suddencardiac death-early access, early cardiopulmonary resuscitation (CPR), early defibrillation, and early advanced life support (ALS). chain of survivalIn emergency cardiac care, the notion that the survival of patients in cardiac arrest depends on the linkage of the following: 1. immediate recognition and activation, 2. early CPR, 3. rapid defibrillation, 4. effective advanced life support, and 5. integrated post-cardiac arrest care. If for any reason any one of these links is missing or delayed, the chance of survival decreases considerably. See: cardiopulmonary resuscitationSee also: chain |
