8. Attach latex needle adapter to
IV needle and IV tubing.
(See
figure 15.)
Proof of proper pro-
cedure will then be evidenced by
the flow of infusion fluid from the
IV bag B. Control flow rate with
clamp on IV set B. This fluid can
be used over. If more realistic
experience is desired with “blood
flashback” instead of water when
inserting butterfly into lumen of
vein, use next procedure C.

C. Recommended Procedure
for Simultaneous IV Infusions
and Drawing Blood
Using two IV bag kits, hook up and
install with IV bag A and IV bag B.
(See figure 16.)
Remove air vent
from bag B.
1. Begin with synthetic blood in IV
bag A. Open clamp on both A and
B to pressurize system. “Flush”
system by allowing “blood” to
flow into container B until bubbles
in tubing disappear, then regulate
blood flow from bag A (using
clamp). System is now full of
“blood” and pressurized. “Blood”
can now be drawn anywhere
along the pathway of the vein.
2. Intravenous infusion — insert but-
terfly into lumen of vein. Proof of
correct insertion is evidenced by
flashback of “blood.” Insert end
of IV tubing into butterfly. Adjust
flow to desirable rate with clamp.
With this arrangement the IV
bag B, when full, may be easily
switched with A.
NOTE:
always regulate flow of “blood”
from the raised bag, and open the
other clamp.
D. Intramuscular Injections
The procedure for administering intra-
muscular injections can be practiced
in the area of the deltoid. Prep the
site with distilled water only. These
injections can be done utilizing the
appropriate needle and syringe.
1
/
2
cc of distilled water may be injected,
however, we recommend utilizing air
as injectant since the distilled water
cannot be drained, but must evapo-
rate from the arm. Synthetic blood
must NEVER be used for injections.
Troubleshooting:
If ”blood” cannot be aspirated during
the blood drawing procedure:
1. The clamp is not opened.
2. There are kinks in the tubing of IV
sets.
3. Tubing has been pinched shut
by constant pressure of pinch
clamps. Lumen remains pinched
occasionally even if pinch clamps
are loosened. Slide clamp to new
position and with fingers manipu-
late tubing at pinched site to
restore lumen. In heavy use, slide
clamp to new position on tubing
from time to time to prevent the
“permanent pinch” caused by
constant clamp pressure. Replace
IV kit.
4. If these measures do not unclog
the venous system, try using a
large 50cc syringe to force fluid
through the tubing.
