Point-of-care ultrasound with pocket-size devices in emergency department.

Point-of-care ultrasound is a useful tool for clinicians in the management of patients. Particularly in emergency department, the role of point-of-care ultrasound is strongly increasing due to the need for a rapid assessment of critically ill patients and to speed up the diagnostic process. Hand-carried ultrasound devices are particularly useful in emergency setting and allow rapid assessment of patient even in prehospital setting. This article will review the role of point-of-care ultrasonography, performed with pocket-size devices, in the management of patients presenting with acute onset of undifferentiating dyspnea, chest pain, and shock in emergency department.
