Model iterative airway pressure reconstruction during mechanical ventilation asynchrony: shapes and sizes of reconstruction

Model-based methods estimating patient-specific respiratory mechanics may help intensive care clinicians in setting optimal ventilation parameters. However, these methods rely heavily on the quality of measured airway pressure and flow profiles for reliable respiratory mechanics estimation. Thus, as...
