Emergency ultrasound is the application of ultrasound at the point of care to make immediate patient-care decisions. It is performed by the health care professional caring for the injured persons. This point-of-care use of ultrasound is often to evaluate an emergent medical condition, in settings such as an emergency department, critical care unit, ambulance, or combat zone.
Famous quotes containing the word emergency:
“War-making is one of the few activities that people are not supposed to view “realistically”; that is, with an eye to expense and practical outcome. In all-out war, expenditure is all-out, unprudent—war being defined as an emergency in which no sacrifice is excessive.”
—Susan Sontag (b. 1933)
