The efficacy of ultrasound (US) in real-time differential diagnosis and guiding further treatment decisions has been well demonstrated in prearrest conditions and during resuscitation. Evidence is limited regarding the application of US in postresuscitation care. Most of the patients following resuscitation remain comatose, and the requirement for transportation to other examination rooms increases their risk of injury. ⋯ For hemodynamic monitoring, left ventricular outlet tract velocity time integral has the best performance in predicting fluid responsiveness in conjunction with the passive leg raising test. The RUSH protocol assists in determining the subtypes of shock with high sensitivity and specificity in hypovolemic, cardiogenic, or obstructive shock. Evidence regarding the application of US for prognostication is still limited, and further evaluation should be needed.
