Abstract: The disclosure relates to determining optimized parameters for mechanical ventilation comprising: obtaining data concerning a three-dimensional image of the subject's respiratory system; calculating a specific three-dimensional structural model of the subject's lung structure from the image data; calculating a specific three-dimensional structural model of the subject's airway structure from the image data; calculating a patient-specific three-dimensional structural model of the subject's lobar structure from the lung model; modeling the air flow through the airway, using the models of the airway and lobar structure of the subject at defined MV parameters; modeling the structural behavior of the airway and the interaction with the flow, using the models of the airway and lobar structure of the subject at defined MV parameters; determining the MV parameters which lead to a decrease in airway resistance and hence an increase in lobar mass flow for the same driving pressures according to the model.
