Quick Reference: Oxygenator Change Out During CPB
Signs of failure: Falling arterial PO2 or falling SVO2 in the presence of 100%, FiO2 and flows at a normal to high cardiac index and adequate anesthesia; membrane gradient > 100mmHg.
- Notify surgeon and anesthesia.
- Wean off CPB if it is possible to do so in the operation.
- Have someone get an oxygenator and the IV pole with holder.
- Turn off ALF purge.
- Clamp venous and arterial lines.
- Double clamp the inlet and outlet lines of the oxygenator.
- Swab area to be cut with alcohol pad.
- Cut lines with sterile scissors or blade.
- Attach both the inlet and outlet to new oxygenator.
- Clamp and remove old arterial sample line from manifold and attach the new line.
- Attach the new oxygenator’s recirculation line to top of the reservoir.
- Prime oxygenator through the recirculation lines.
- Transfer the gas line to the new oxygenator.
- When de-bubbled, close the recirculation lines and resume CPB.
- Drain back the water lines and then attach them to the pigtails on the new holder.
