6. Insert an IV needle (or butterfly)
into the vein. “Flashback” will indi-
cate a proper insertion.
7. Close the clamp on IV bag A and
remove the pinch clamp from leg
tubing at the basin.
Figure 11
8. Attach the latex needle adapter
to the IV needle (or butterfly) and
bag B IV tubing. Open the clamp
on bag B. (
See figure 11. This
figure shows only the correct
attachment of the latex needle
adapter. During the actual proce-
dure, the butterfly needle would
have already been inserted into
the vein at this point.) Proof of
proper procedure will then be
evidenced by the flow of infusion
fluid from IV bag B. Control the
flow rate with the clamp on IV
bag B. This fluid can be reused.
H. Recommended Procedures for
Simultaneous “Blood” Drawing
and IV Infusions
Use two IV bag kits. Hook up and
install IV bag A as shown.
(See
figure 12.)
1. Drawing “Blood” — Begin with
synthetic blood (or distilled
water) in bag A. Do not hang bag
A more than 18" over the level of
the simulator. “Flush” the system
by allowing fluid to flow into a col-
lection dish until all the bubbles
in the tubing are gone. Close the
mini clamp on the tubing running
to the dish. The system is now
full of “blood” and pressurized.
“Blood” can now be drawn any-
where along the pathway of the
vein.
2. Intravenous Infusion — Insert
the butterfly into the lumen of
the vein. Proof of a correct inser-
tion is evidenced by a flashback
of “blood.” Now close the clamp
on bag A, remove it, and reattach
it to the butterfly using the 2" latex
adapter. Take bag B (empty),
attach it where bag A had been
connected, and lay it by the simu-
lator, making sure the mini clamp
is closed.
