8.
Visually confirm that all air bubbles have been removed from the syringe. Tap the pressure
jacket after filling to facilitate air removal.
9.
Secure the distal connector of the high pressure connector tubing.
10.
Turn the Manual Knob clockwise to push contrast out until all of the air bubbles have been
removed from the high pressure connector tubing. Gentle tapping at any connection point
may be needed to facilitate air removal.
11.
Use the handle and the back of the Injector Head (but not the Manual Knob or tubing) to
rotate the Injector Head to the Inject (downward) position.
12.
Secure the catheter hub in one hand and the distal rotating luer of the high pressure
connector tubing in the other hand.
13.
Advance the piston using the Manual Knob prior to connecting the high pressure connector
tubing to a catheter or other non-Bayer disposables including administration sets and
additions to administration sets, such as but not limited to bleed back control devices and
pressure transducers.
14.
Securely tighten the high pressure connector tubing connection to the catheter or other non-
Bayer disposables including administration sets and additions to administration sets, such as
but not limited to bleed back control devices and pressure transducers.
15.
Aspirate via the manual knob when connecting to the high pressure connector tubing and a
catheter or other non-Bayer disposables including administration sets and additions to
administration sets, such as but not limited to bleed back control devices and pressure
transducers to ensure all air has been removed from the fluid path.
16.
Stop aspirating with manual knob once blood is visualized in high pressure connector tubing.
17.
Verify that there is no air in the high pressure connector tubing.
a.
If there is air in the tubing, disconnect from patient, remove air, and try fluid to fluid
connection again.
18.
Once it has been established that all air has been removed, advance the Manual Knob
forward to clear blood from high pressure connector tubing.
