3. Be sure the clamp on the IV tub-
ing is closed, and hang the bag
no more than 18" above the level
of the arm.
4. Attach the end of the IV tubing to
one of the shoulder tubings.
5. With the other shoulder tubing in
a basin or sink, gradually “flush”
the vascular system with syn-
thetic blood by slowly opening
the clamp. Allow some “blood” to
pass through the system until the
air bubbles have been eliminated.
6. Once the system is filled, use one
of the pinch clamps to close off the
blood outlet tubing. The venous
system is now full of “blood” and
pressurized. Be sure to leave the
clamp on the IV tubing open.
7. After filling the venous system
according to instructions, the
arm is now ready for you to
practice drawing blood. Blood
can be drawn anywhere along
the pathway of the vein. Distilled
water, rather than alcohol, should
be used to prepare the sites.
Synthetic blood will actually be
aspirated once the vein is prop-
erly punctured.
8. Small diameter needles (20- to
25-gauge) should be used.

B. Preparing the Arm for
Intravenous Infusions
1. Close the clamp at the end of IV
bag A tube, then fill with water
(distilled water is recommended),
and hang not more than 18"
above the arm.
(See figure 14.)
2. Appropriate intravenous infusion
needles (or butterflies) should be
used, and distilled water is rec-
ommended as an infusion.
3. IVs can be started anywhere
along the pathway of the simu-
lated vein. Cleanse the sites with
distilled water only.
4. Attach the adapter end of the IV
tubing into one of the shoulder
tubing ends.
5. Place the other shoulder tubing
end in a basin or jar, and “flush”
the vascular system by opening
the clamp. Allow infusion (water)
to pass through the system until
air bubbles are eliminated. Shut
off the flow with a pinch clamp.
The venous system is now full
and pressurized.
6. Insert an IV needle or butterfly in
the vein. “Flashback” will indicate
proper insertion.
7. Close the clamp on IV bag A tube
and remove pinch clamp from
shoulder tubing.
