Instructions for use: Ikus - Berlin Heart

Intraoperative drive management
Start up the Ikus and set the parameters
Caution!
• Do not bend the driving tubes!
6.2.6 De-air the pump(s) in single-step mode
Note
• With each de-airing step, one half pump cycle (= one systole or one diastole) is covered;
first step: diastole. Normally, several de-airing steps are required for each pump.
• The pumps work in single-step mode with the pressures shown in the parameter table.
• Only when at least one de-airing step per pump has been performed is it possible to
switch to normal view.
Instructions
1. Bring the patient into the Trendelenburg position.
2. Move the cursor into the field “Step left”.
3. Lift up the pump. The de-airing nipple of the blood pump is the highest point.
4. Confirm with to trigger a single-step. If necessary, de-air the pump via the
de-airing needle (see page 43). In consultation with the surgeon: With , trigger
additional individual steps until the pump is completely de-aired. If the pump does not fill
correctly: If necessary, increase the suction pressure slightly.
5. During biventricular mode: Move the cursor into the field “Step right”. Repeat the deairing
with the second pump.
Single-step mode; transfer to constant mode is not yet possible (OK is deactivated)
6.2.7 Start the pump (switch to normal view)
Warning!
• Only start the blood pump(s) after they are completely de-aired!
• Only remove the de-airing needle if the blood pump is running and the parameters have
been adjusted (see below and page 51).
Instructions
1. Move the cursor to OK, then confirm with . The system now starts with the
parameter values visible in the parameter table.
6.2.8 Check and adjust the parameters when the pump is started
Warning!
• Adjust all parameters only gradually to prevent the aspiration of air into the blood pump
through the cannula anastomosis. However, should air get inside the system, pull the
driving tubes off the driving unit and de-air the system via the de-airing needle.
• Constantly monitor all of the settings.
Instructions
1. Observe the left blood pump. Does the pump eject completely? If not: If necessary,
increase the driving pressure on the left.
2. Observe the right blood pump. Does the pump eject completely? If not: If necessary,
increase the driving pressure on the right.
