Problem 

Cause of problem / action to be taken 

Deposits in the 

Initial deposits: check anticoagulation status and adjust 

pump 

therapy if necessary. 
If floating deposits are detected (may cause 
thromboembolic complication): replace the pump, see 
section 15.1: Replacing the blood pump(s), page 195. 

Visible blood pump 
faults 

Replace the pump, see section 15.1: Replacing the blood 
pump(s), page 195. 

Pump membrane 

Possible causes: 

remains in the 
diastolic or systolic 
position despite 
vibration / 

•  kinking of the cannula 
•  clotting of the pump 
•  partial malfunction of the Ikus 

movement of the 

What to do? 

pump indicating 

Check for external forces on the cannula and whether it 

that the Ikus is 

may be necessary to manipulate the cannula, see 

attempting to 

section 14.4: Please check left / right pump and driving 

provide diastolic or 

tube, page 175. 

systolic pressure 

Check for clots in the pump or cannula that may be 
obstructing flow and replace the pump if necessary, see 
section 15.1: Replacing the blood pump(s), page 195. 
Initiate hand-pumping to try to eject the pump, see 
section 15.5: Driving blood pump(s) with the manual 
pump, page 204. 
Switch the patient to the back-up Ikus driving unit, see 
section 15.4: Connecting the patient to a replacement 
Ikus, page 202. 

Pump membrane 

Additional possible causes: 

remains in one 
position despite the 
above 

•  High vascular resistance 
•  Defective blood pump 

manipulations 

There may be air leaking into the space between the first 
and second layer of the triple-layer pump membrane. This 
accumulated air may gradually create a “pillowing” effect 
between the membranes. 

The top (visible) membrane layer will appear to be 
continuously in diastole while the bottom two membrane 
layers are in fact continuously in systole.
