The present study examines an alternative and innovative mechanical ventilation modality in improving oxygen delivery, CO 2 clearance, and respiratory mechanical abnormalities in a clinically relevant experimental model of capnoperitoneum. Our data reveal that high-frequency oscillations combined with conventional ventilation improve gas exchange, with intratracheal oscillations being more effective than extrathoracic oscillations in this clinically relevant translational model.

The present study examined the contributions of the lungs and chest wall to respiratory complications in a rat model of diabetes and clarified the effects of metformin on these changes. At low positive end-expiratory pressure, type 2 diabetes was linked to dysfunctional airway and lung tissue mechanics in relation with gas-exchange defects and collagen overexpression, whereas decreased tissue hysteresivity was manifested in the chest wall abnormalities. Metformin treated all adverse respiratory consequences of diabetes.
