Rianimazione cardiopulmonare.

Here we describe the evidence for point-of-care ultrasonography application in cardiac arrest. Most commonly, transthoracic echocardiography and transesophageal echocardiography imaging may identify reversible etiologies for arrest, guide chest compression quality, and provide prognostic information. Many arrest ultrasound protocols have been described, and emphasize qualitative assessment of cardiac and respiratory pathology while minimizing disruption to chest compressions.
