Arterial Bloodline Setup
1. Close the medication port clamp located on the short line at the top of the compliance
chamber.
2. Snap the compliance chamber into its holder.
3. Connect the arterial monitor line to the pressure port (P
Pump module using a transducer protector. Verify that the monitor line is unclamped.
Warning! Transducer protectors should be used between transducers and each pressure
monitor line of the extracorporeal system to prevent the transducers from getting wet. Wet
transducer protectors must be replaced, as they will cause inaccurate pressure readings. If
the external transducer protector and the internal transducer should become contaminated
with blood, the transducer protectors must be replaced, and the transducer must be
disinfected or replaced.
4. Locate the "pillow" on the patient end of the arterial bloodline; the pump segment
directly above the pillow is the first blood pump segment, this pump segment should be
loaded into the arterial blood pump (the first blood pump from the left).
5. Open the arterial blood pump door.
Warning! Inspect the blood pump rotor for proper operation (tubing guide posts not bent,
rollers move freely, crank lever moves freely). Bent or loose tubing guide posts can damage
bloodlines. Replace rotor if necessary. See page 127 for rotor diagram.
6. If necessary, set the Arterial Blood Pump module for the diameter of the blood pump
segment:

Press the Up () and Down () keys on the Arterial Blood Pump module
simultaneously. The display will flash.

Press the Up () or Down () key on the Arterial Blood Pump module until the
diameter of the pump segment (8.0) being used is displayed.
7. Load the arterial blood pump segment into the arterial blood pump:
a. Press and hold the Start/Stop key on the Arterial Blood Pump module to align the
pump rotor for line insertion.
b. Grasp the pump segment and, using thumb pressure, position it behind the left yoke
by pressing the tubing retainer inward. Be sure the end of the segment clears the
bottom of the yoke.
Warning! Make sure the collar of the pump segment is positioned below the bottom of the
yoke. This will minimize the possibility of the segment kinking during pump operation.
c. Press and hold the Start/Stop key. The rotor will rotate to the 5 o'clock position and
stop. Relieve pressure on the retainer and release the segment. The beginning of the
pump segment should be secured between the left yoke and the tubing retainer.
Warning! Keep fingers free of rotor while it is turning to avoid possible injury.
d. Press and hold the Start/Stop key again and the rotor will rotate one full turn to
automatically position the remainder of the segment within the pump housing. After
loading, any extra pump segment tubing length should be on the right side of the
pump.
