Determination of gas flow during different parts of the respiratory cycle in an example of EIT data measured during pressure controlled ventilation in the global region-of-interest. Blue line: measured and calibrated EIT signal, VEIT(t) is gas content over time. Red line: calculated flow signal from EIT data, V’EIT(t) is gas flow over time. Late inspiratory and expiratory flow (PIF, LIF, PEF and LEF) are derived from gas flow data.
