How To Do Ultrasonography
Introduction
Bedside ultrasonography is increasingly used in acute care settings to assist both diagnosis (eg, fluid accumulations or foreign bodies) and treatment (eg, intravenous catheterization or arthrocentesis). Ultrasonography equipment includes probes, consoles or instrument controls, and monitors. Some portable devices work on software apps in handheld devices. Point-of-care ultrasonography should be done only by trained personnel.
