Terumo CAPIOX EBS Circuit with X coating, Instructions For Use Manual

Initiation of BYPASS
・ Prior to starting circulation, confirm that priming line is
closed as well as 3-way stopcocks for removing bubbles
and those of the sampling port. If the 3-way stopcocks
are not closed, bubbles may enter the circuit as the
pressure inside the venous line (blue) is negative during
circulation.
・
Prior to delivering gas, confirm that the gas port
(GAS OUT) is not blocked up. Otherwise, the pressure of
the gas side in the oxygenator will increase, and bubbles
will flow into the blood side.
・
Make sure that the underside of the centrifugal pump is in
close contact with the pump receptacle and that the slide
hook is in position.
1. Open the clamp of the venous line (blue) and forceps on the tube of the
venous cannula (blue).
Do not operate the pump with the venous line (blue)
clamped. Otherwise, negative pressure would be
generated inside the pump and bubbles would be formed in
the blood.
2. Start the rotation of the centrifugal pump and set the pump speed at
around 1000rpm.
3. Gradually release the clamp on the arterial line (red) to start circulation
(Figure 20).
After-load pressure higher than the pump's outlet pressure
causes back flow of the blood. To prevent this, do not
unclamp the outlet of the pump at the start of circulation, until
an adequate outlet pressure has been reached. (Refer to the
data on Pump performance (19 page).)
4. Start gas supply.
・
Start gas supply only after blood circulation is initiated.
・
Start gas supply with V/Q = 1 and FiO2 = 100%.
5. Adjust the pump speed of the centrifugal pump console for appropriate
flow rate.
During perfusion
Never clamp the venous line (blue) during circulation.
Otherwise, negative pressure would be generated inside
the pump and bubbles would be formed in the blood.
