1.6. ChECk ThE COrrECT ELECTrOdE BELT POSITIOn
The following procedure will help you to check the belt position or to find the
correct position.
The belt is to be placed between the 4
th
and 6
th
ICS. For women, the belt
should be placed onto the breast.
Case A:
If the belt is placed too far caudally, movements of the diaphragm affect
the imaging.
Effect:
Negative impedance changes (see page 34) become visible
laterally in the Tidal Image. This is an indicator that the belt is
too low.
Case B:
If the belt is placed too far cranially, the ventilated lung regions may
appear smaller.
Effect:
Due to the low spatial resolution, it is no longer possible to
clearly distinguish between the left and right lungs, especially
if the mediastinum can no longer be localized in the apical
region of the lungs.
