3. Useful Tools and Tips
3.1. COnTOUr OF vEnTILaTEd arEa
With the help of the ›contour of ventilated area‹, it is possible to track the
ventilated lung regions in form of a virtual footprint. The contour allows the
delimitation of the ventilated regions per breath and the identification of lung
regions with e.g. restricted ventilation or delayed inspiratory procedures. The
setting of the contour of ventilated area is located in the setup menu ›Display‹.
The contour is displayed in the dynamic image (main view, fullscreen) as well
as in the end-inspiratory trend. In the dynamic image the contour represents
the area of the last detected breath. In the end-inspiratory trend view, this
contour marks all the ventilated lung regions in the selected observation period
(1 min - 120 min). Depending on the cursor position (
Ref, C), non-ventilated
areas are marked in grey.
