Y1 - 2021 N1 - T2 - Ma and Mateer's Emergency Ultrasound, 4e AB - The management of critically ill patients becomes more challenging when they are hemodynamically unstable or clinically deteriorating, and the underlying etiology of their condition is unclear. This often occurs shortly after arrival to the emergency department (ED), but it can also occur in other parts of the hospital hours or days after care has been established, with unexpected deterioration of a previously stable patient. In these situations, clinicians are often forced to make treatment decisions before diagnostic tests can be performed. A focused physical examination of the critical organ systems is often inaccurate or misleading. Point-of-care ultrasound (POCUS) can rapidly examine the same organ systems with a higher degree of accuracy.
