The more you delve into cardiac arrest, the more it seems that delivering the essentials well is the key to great outcomes; timely recognition, high quality chest compressions, with early and appropriate defibrillation. But is ultrasound in cardiac arrest a layer that we should all be adding in as a standard. It holds the potential to not only prognose outcomes from cardiac arrest, both medical and traumatic, but also to add a level of diagnosis of potentially reversible causes. In this podcast we chat through the evidence surrounding ultrasound in cardiac arrest and consider the practicalities of application during delivery of patient care. Make sure to take a look at the references and resources below. Enjoy! Simon, Rob & James
