There are three possible training levels in which to practice EMUS.
However, there are many applications of EMUS. The most notoriety has been attached to trauma and the focussed assessment using sonography in trauma (FAST) scan. In fact, it is probably more used in the assessment of abdominal pain where an abdominal aortic aneurysm (AAA) may be the cause.
Central vascular access can be carried out much more safely and reliably due to the direct visualisation that ultrasound affords. Peripheral vascular access can be carried out in situations where veins cannot otherwise be found.
Foreign bodies may be seen, and pus collections confirmed, with very limited skills. More advanced use includes assessment of obstructive uropathy, foetal visualisation, assessment of gall bladder pathology, deep vein thrombosis and musculo-skeletal assessments.
