Chapter 13 Weaning and Explantation for BTR and BTT
Do not switch the Ikus off unless the batteries are fully charged. Leave
the Ikus switched on until all yellow LEDs light up, then switch off the
Ikus with main switch (key switch).
Keep all driving tube connectors covered at all times when not in use.
INSTRUCTION
1. Put the patient on cardiopulmonary bypass (CPB).
2. Disconnect the driving tubes and connect both tank units to the Ikus.
3. Leave the Ikus running with the tank units until the patient is stable on CPB
and the blood pumps have been explanted.
4. Next in the monitor program, select the option Drive OFF (see Fig. 13-2,
page 169) and press <Enter> to confirm.
5. Respond to the prompt in the dialog window by pressing the <X> key or the
<1> key. The system stops operation immediately and writes an operating log.
6. Disconnect the driving tube(s) from the connector(s). To do so, take hold of the
plug's release sleeve and pull the plug out of the connector.
7. Use the seal plugs to seal the driving tube connector sockets.
8. Wait until the log has been completed. When the message Switch drive off
with main switch! appears, press <F10> to shut down the monitor program.
Confirm by pressing the <X> key or the <1> key.
9. Select 3. End ( <3> , see Fig. 13-3, page 169) in the start menu and switch off
the laptop.
10. Switch the Ikus off, provided that the batteries are fully charged. To do so, turn
the key switch to
[0] position.
13.3 Explantation for BTT
NOTICE
When planning and timing the transplantation, be aware that massive
adhesions may exist in the transplant recipient.
Preparing the donor organ
ADVICE
Leave adequate lengths of the aorta and the pulmonary artery attached
to the donor organ in order to be able to continue using those parts of
the original vessels used for anastomosis of the VAD cannulae.
Leave the Ikus running with the tank units until the patient is stable on
CPB and the blood pumps have been explanted.
Switching the Ikus off
WARNING
The Ikus power switch (toggle switch) should always be in the [I]
position, even if the main switch (key switch) is in the [0] position!
Otherwise there is a risk that the drive may fail due to the Ikus batteries
being totally discharged.
