Xltek ICU system - Quick Start Guide
1. Plug the machine to the mains socket and press the ON button on the bottom right of the
monitor.
2. The Monitor will finish loading with the Database software opening automatically (alternatively,
you can launch it by clicking on Natus Database icon on the desktop).
3. Prepare your patient:
a. Prepare the areas on the head for the electrode placement (6 of them);
b. Place 4 recording electrodes (corresponding to F3, P3, F4, P4) and connect them to the headbox
accordingly;
c. Don’t forget one REF and one AUX/COM electrodes.
F3
P3
F4
P4

4. Within the Database window, click New to start a new study (if recording for a pre-existing
patient, highlight the name and select Returning).
5. Type in the patient’s names and hit Start.
6. Allow the system a couple of seconds to load the appropriate tables; it will then automatically
start checking impedances. Make sure that the 4 recording electrodes (F3, F4, P3, P4) show green
impedances. REF and COM electrodes are not included in this check. Hit End when you are happy
with the results.
(NB: the positioning of the electrodes on the table may differ from the example below)
7. As the Impedance Checks table disappears, data recording (plus video) begins automatically.
8. CFAM/aEEG trace window will display approx 4 hours per screen (see Elapsed Time axis).
Timescale can be changed by clicking on Trends Scale button.

9. Your patient’s daily care routine can affect the CFAM/aEEG trace, therefore it is helpful to make a
note of your actions (such as caring, feeding, electrodes becoming loose, etc). There’s several ways
to annotate:
a. Click any key on the keyboard and a Note box will open. Write a brief description and click OK.
b. Click on Custom…at the top of the screen - it will also bring the Note box.
10. The video will be recording automatically. You can zoom in and out using Camera Control button.
Tip: don’t zoom in too close; there’s an option to zoom in further when reviewing as well.
12. The recording software will close and you will be back in the Database view.
13. To turn the machine off, click on the Windows Start button and select Shut Down.
