Quick Reference: Vacuum Assisted Venous Drainage
- Connect vacuum line from the wall to the
regulator on the right mast of the pump and set it to -50mmHg. - Attach the vacuum assist tubing set to the
regulator on the left mast of the pump. - Test the regulator so the vacuum range is from
-20 to -50mmHg. - Attach the other end of the vacuum assist tubing
to the vent port. - Measure the negative pressure on the venous
reservoir with a pressure transducer. - Once on CPB, clamp the pigtail on the vacuum
assist tubing. - Adjust vacuum as necessary to increase drainage. Do not exceed -50 mmHg.
- Communicate with anesthesia to make sure all IVs
are turned off. - With a centrifugal pump, positive flow needs to
be maintained at all times. - Always release the vacuum when going down on
flow or weaning from CPB.
