5. Fig 4
Longitudinal scan of a venous cannula inside the GSV (indicated by the vertical transparent arrow). Owing to the two-dimensional image, only parts of the cannula can be visualized as a double-layer structure. The white arrow indicates the jelly pad (which is slightly compressed due to the weight of the ultrasound probe) and the grey arrow indicates the GSV.
