Standard form: Blood pump replacement
Appendix
13.8 Standard form: Blood pump replacement
Warning!
• Replace the pump under sterile conditions!
• When connecting the blood pump(s), pay attention to the arrows on the inflow and
outflow stubs. These show the blood flow direction.
• If the left blood pump is replaced in biventricular mode, the right pump must also be
stopped for the duration of the replacement to prevent overloading of the pulmonary
circulation (risk of pulmonary edema).
Cautionary measure
• Sedate your patient slightly and administer a heparin bolus.
Material
• 1 Blood pump of appropriate type and size
• 1 driving tube (red or blue)
• 1 accessory set (for blood pumps with PU valves or tilting-disk valves)
• 1 tube attachment set from accessory set (cable tie strap, cable tie pliers)
• or connecting set (may be necessary if the replacement pump has a larger volume than
the pump to be replaced)
What OK
Prepare the replacement pump: Bring the membrane into the end diastolic position, situate the de-airing
needle, rinse and fill the pump with sterile saline solution.
Fit the new driving tube onto the driving tube connector of the pump.
Lay out the pump. The titanium connectors face upward.
Lay out the pump. The titanium connectors face upward.
Bring the patient into the Trendelenburg position.
Carefully cut through the cable tie strap on the inflow and outflow cannula of the faulty pump.
Immediately check the cannulas for integrity.
If necessary, log on to the monitoring program: Enter the user number and password, then confirm

As soon as the pump has stopped, disconnect the cannulas underneath the faulty pump and slide them
off the pump.
Check the cannulas for deposits. If necessary, remove the deposits carefully.
Pull the driving tube of the faulty pump out of the connector. To do so, grab the plug by the ribbed plug
body and pull it out of the connector.
Close the connector on the Ikus that has become free with the seal plug.
Moisten the free cannula ends with sterile saline solution. Ensure that they are absolutely free of air.
Connect the prepared replacement pump to the cannulas.
The view “Operating mode” appears in the monitoring program. Select Univentricular or biventricular, then
confirm the desired operating mode with . In biventricular mode, the view “Pump size and singlestep
mode” follows. In univentricular mode, the connector seal test follows first, ad then the view “Pump
size and single-step mode”. If the backup pump is larger than the pump to be replaced: Adjust the parameter
pump size!
Pull the seal plug out of the connector. When replacing the left pump: red marked connector; when replacing
the right pump: blue marked connector! Insert the plug of the new driving tube into the connector that has
become free. The plug snaps audibly into place.
Check that the plug is firmly seated. To do so, pull the plug above the ribbed plug body. Never pull on
the tube!
Loosen the tube clamps on the cannulas.
In the monitoring program, move the cursor to the single-step mode field.
Confirm “Step left” or “Step right” with to trigger a single-step. With , trigger additional
individual steps until the pump is completely de-aired. If the pump is completely de-aired: Remove the
de-airing needle. When replacing the left pump: In the monitoring program, move the cursor to “Step
right”, then confirm with .
Move the cursor to OK, then confirm with . The system restarts with the set parameters.
Observe the pump filling. If necessary, adjust the parameters.
Secure all the connections with cable tie straps.
