you can change this to Minute Image (Setup). Real-time impedance curves
represent ventilation over time. Changes in the overall cross-section are reflected
by the Global Impedance Curve . This curve strongly correlates with the volume
curve of the ventilator and with the applied/inhaled total volume. The regional
impedance changes (i.e. tidal variations) serve to compare different lung regions.
The numerical values indicate the volume distribution, which together add up to
100 % of the global value unless the overall window size (ROI setting) is changed.
