Chapter 1 Important safety information
1.1.12 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!
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.
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.
If the left pump is being replaced in a VAD providing biventricular
support, the right pump must also be stopped while the pump is being
replaced in order to avoid overloading the pulmonary circulation
(danger of pulmonary edema).
If air or blood collects between any of the layers of the membrane,
replace the blood pump. Otherwise, support may be inadequate.
1.1.13 Driving blood pump(s) with the manual pump
WARNING
The use of the manual pump is only permitted for medical personnel
trained in the use of it.
Pay attention to the colored markings on the driving tubes and on the
connectors of the manual pump. Otherwise, there is a risk of lung
edema.
Always keep manual pump attached to the Ikus. Otherwise in an
emergency situation the adequate support of the patient is not
guaranteed.
Call one or more persons to assist. Otherwise in an emergency
situation the adequate support of the patient is not guaranteed.
The driving tubes and cannulae should be arranged in a bend-free
position. Otherwise in an emergency situation the adequate support of
the patient is not guaranteed.
