15.1 Replacing the blood pump(s)
WARNING
When replacing a blood pump, follow the instruction given here.
Otherwise the duration of the pump stop will be prolonged and the
patient might suffer from inadequate support.
The blood pump may only be replaced under sterile conditions!
All effort should be made to minimize the manipulation and distortion of
the blood pumps and cannula during the removal of the cable tie(s) to
prevent mobilization of deposits.
The cable tie covering the EXCOR cannula on the stub of the blood
pump should be removed carefully. Use an appropriate blunt tool.
Important: never use a sharp instrument, for example, a scalpel or
scissors, to remove the cable tie. This may cause damage to the
cannula.
BVAD: If the left pump is being replaced, the right pump must also be
stopped while the pump is being replaced. Otherwise there is the risk
of pulmonary edema.
When connecting the blood pump(s), pay attention to the direction of
the arrows on the inflow and outflow stubs! These show the direction of
the blood flow.
NOTICE
If the replacement pump has a larger volume than the one being
replaced,
the use of a connector set must be considered
the corresponding parameter in the view
Pump size and single-step
mode must be updated.
IMPORTANT: When 2 blood pumps need to be replaced, replace the right blood pump
in the first place, subsequently replace the left blood pump.
IMPORTANT: Sedate the patient if necessary and administer a bolus of Heparin
according to the anticoagulation protocol.
When using a cannula extension set / connecting set: See section 9.3: Cannulae,
cannula extension set and connecting set, page 117.
