Critical Care Nursing Quarterly: April/June 2018 - Volume 41 - Issue 2 - p 94-101 doi: 10.1097/CNQ.0000000000000190 Buy Metrics Abstract To stabilize critically ill patients, emergency and critical care medicine providers often require rapid diagnosis and intervention. The demand for a safe, timely diagnostic device, alongside technological innovation, led to the advent of point-of-care ultrasonography (POCUS). POCUS allows the provider to gain invaluable clinical information with a high level of accuracy, leading to better clinical decision-making and improvements in patient safety. We have outlined the history of POCUS adaptation in emergency and critical care medicine and various clinical applications of POCUS described in literature. © 2018 Wolters Kluwer Health, Inc.
