Fig. 2

Schematic representation of the pendelluft phenomenon occurring during assisted mechanical ventilation. Pendelluft (black arrows) was defined as the sum of the gas moving into early-inflating regions of interest during expiration (before the global electrical impedance tomography value reached its minimum value, T0 in the text, panel a) and the gas lost by late-deflating regions of interest during inspiration (after T0, panel b)
