Intraoperative drive management<br />
Start up the <strong>Ikus</strong> and set the parameters<br />
remains identical.<br />
• separate pulse is sometimes helpful in patients with intracardial shunts.<br />
<strong>Instructions</strong><br />
1. Move the cursor with ← / → to the field with the current operating mode display.<br />
A popup menu appears showing the possible operating modes.<br />
2. Select the desired operating mode with ↓,↑, then confirm with . The system<br />
works in the set operating mode.<br />
Target values<br />
Systole [mmHg]<br />
left/right<br />
The most important criterion when selecting the drive parameters is good filling and emptying<br />
of the pump; the settings must be oriented toward achieving this goal.<br />
Note<br />
• The systolic driving pressure must be higher than the systolic pressure of the patient.<br />
Important: When the systolic duration is shortened or with very small cannulas, a higher<br />
value may need to be selected than recommended here.<br />
• The driving pressures reached are dependent on the diameter of the cannulas <strong>use</strong>d.<br />
• The following values are only guideline values; they are not authoritative in individual<br />
cases!<br />
Diastole [mmHg]<br />
left/right<br />
Recommended target values <strong>for</strong> normal operation<br />
Recommendation<br />
• Now remove the de-airing needle (see page 51).<br />
Warning!<br />
• On removing the de-airing needle, never pull on the de-airing tube, but rather on the deairing<br />
needle itself.<br />
6.2.9 Switching from HLM to VAD<br />
Rate [bpm]<br />
220/150 -40/-40 80 40/40<br />
rel. systolic duration [%]<br />
left/right<br />
The goal is to reduce the HLM flow and thus shift the volume from the HLM to the<br />
patient (to the VAD).<br />
<strong>Instructions</strong><br />
1. If firstly the right blood pump and then the left blood pump too begin to fill, reduce the<br />
HLM flow and increase the EXCOR rate firstly from 30 bpm stepwise, until the desired<br />
flow is reached. Important: In doing so, ensure sufficient filling, and if necessary regulate<br />
the driving pressure!<br />
2. If necessary, regulate the suction pressure.<br />
Note<br />
• If stage cannulas or a connecting set are <strong>use</strong>d, the pumps do not eject fully at a rate<br />
of > 100 bpm. With these cannulas, rates of > 100 bpm should be avoided.<br />
Recommendation<br />
• To secure the driving tubes to the cannulas, as soon as the system is running stably<br />
(see page 51).<br />
