Some advantages of the CSE technique with this model:

1. The silhouette blocks the view of the "epidural space" from the student.

2. The teacher can move the Latex tubing in or out of the path of the spinal needle.

3. The teacher can increase or decrease the depth of the "epidural space" and pressure of the C.S.F.

4. The student can actually look into the "epidural space" and confirm the length of the catheter inside the space.
