Echocardiography in cardiopulmonary resuscitation [ecocardiografía en reanimación cardiopulmonar]

Cardiac arrest is a clinical entity that is frequently found in emergency services and critically ill units, with cardiopulmonary resuscitation (CPR) techniques being an integral part of the core training of each emergency medical provider.The use of focused cardiac ultrasound (FoCUS) is a cost-effective adjunctive tool for the management of CPR in the hospital environment.The literature supports its value as a prognostic examination of negative survival in the absence of spontaneous cardiac movements, asystole and true pulseless electrical activity (PEA).In addition, it includes a positive prognostic factor for recovery from spontaneous circulation (ROSC) and hospital survival in pseudo-PEA.The FoCUS will allow the limited and early diagnosis of reversible causes of PCR in non-defibrillable rhythms and, subsequently, guide and evaluate the therapeutic measures used during CPR.Serial evaluation by echocardiography after ROSC can guide treatment and establish prognosis in these patients.
