Cardiac Arrest Sonographic Assessment (CASA)

  • 294 Accesses

Abstract

The role of point of care ultrasound (POCUS) in cardiac arrest has evolved over the last several years. Reports have shown that POCUS performed during arrest can lengthen pulse checks. In response, the Cardiac Arrest Sonographic Assessment (CASA) was developed. CASA is a protocol which identifies reversible causes of cardiac arrest while minimizing interruptions of high-quality cardiopulmonary resuscitation (CPR) [1–3]. Additionally, CASA provides a simplified, stepwise approach to minimize provider’s cognitive load during resuscitation. In the future, we may see a change in CPR protocols as transesophageal echocardiography (TEE) becomes more widespread.
