■ The chest wall is transparent, made of special materials, and the venous access on both sides can produce a see-through effect.
■ The anatomical position is correct: the precious vein, the cephalic vein, the jugular vein, the subclavian vein and the superior vena cava, etc.
■ The ribs and heart can be visualized to measure the correct insertion length of the catheter.
■ The superior vena cava is partially transparent. After the catheter is inserted correctly, the position of the catheter can be seen. If it is inserted incorrectly, it cannot be seen.
■ Practice the positions of standard venous cannulae.
