Ultrasound as a tool for fluid status assessment in the trauma and critically ill patient.

Resuscitation to euvolemia in trauma as well as in the critically ill patient, continues to be a challenge. Focused cardiac ultrasound has been shown to be a reliable tool to evaluate fluid status and to guide therapy. The present manuscript reviews the evidence supporting the use of this tool and describes the clinical applications for image-based resuscitation using echocardiogram.
