Positive end-expiratory pressure-induced changes of the vibration response image

Abstract

Vibration response imaging (VRI) is a new modality that reflects the distribution of vibration in the lung during the respiratory process. The VRI dynamic and functional image has been proved to be sensitive to changes in ventilator settings, including changes in mode of mechanical ventilation. In the present study, we assess the changes of the VRI image and quantification data as a function of positive end-expiratory pressure (PEEP) changes.
