Ultrasound also plays a significant role in emergency and critical care settings. In emergency rooms, point-of-care ultrasound (POCUS) is frequently used by physicians to make rapid assessments of trauma patients. It can quickly identify internal bleeding, cardiac tamponade, pneumothorax, and other life-threatening conditions, enabling faster decision-making and potentially life-saving interventions. In intensive care units, ultrasound assists with the placement of central lines vascular ultrasound, the assessment of fluid status, and the monitoring of organ function, contributing to more precise and safer patient care.
