Laerdal Virtual IV - Manual (Page 35)

5.2 Needle Insertion and Skin Stretch
The device should be placed on the desktop, resting flat on the surface. The handle is gripped using
the hand and the thumb can be used to stretch the skin during the procedure. The needle and cath-
eter are inserted into the receptacle. Initially, the learner will feel a slight tug as the device engages the
needle.
Note: Once the needle engages the haptic device, the simulated needle on the screen
will illuminate and you will hear a sound; this means you may proceed with needle
insertion.
The force feedback provided to the learner depends on the patient being cannulated, the case sce-
nario, the actual stick, and any complications. In some cases the learner will feel a stick through both
skin and vein, in other cases the vein, or even the skin puncture may be more or less prominent. The
forces associated with catheterization are subtle at times, and the force feedback device simulates
these subtle cues and sensations.
