- ItemPositive end-expiratory pressure increases strain in patients with ALI/ARDS(2011) Bugedo Tarraza, Guillermo; Bruhn, Alejandro; Regueira Heskia, Tomás; Romero, C.; Retamal, J.; Hernández P., GlennThe study aimed to evaluate a methodology to quantify the porosity of the soil using computed tomography in areas under no-tillage, conventional tillage and native forest. Three soil management systems were selected for the study: forest, conventional tillage and no-tillage. In each soil management system, undisturbed soil samples were collected in the surface layer (0.0 to 0.10 m). The tomographic images were obtained using a X-ray microtomography. After obtaining the images, they were processed, and a methodology was evaluated for image conversion into numerical values. The statistical method which provided the greatest accuracy was the percentile method. The methodology used to analyze the tomographic image allowed quantifying the porosity of the soil under different soil management. The method enabled the characterization of soil porosity in a non-evasive and non-destructive way.
- ItemTidal volume is a major determinant of cyclic recruitment-derecruitment in acute respiratory distress syndrome(EDIZIONI MINERVA MEDICA, 2011) Bruhn, A.; Bugedo, D.; Riquelme, F.; Varas, J.; Retamal, J.; Besa, C.; Cabrera, C.; Bugedo, G.Background. Overdistension and cyclic recruitment-derecruitment contribute to ventilator-induced lung injury. High tidal volumes are thought to increase mortality mainly by inducing overdistension. However, experimental evidence suggests that tidal volume (VT) may also influence cyclic recruitment-derecruitment. Our main goal was to determine whether high tidal volumes increase cyclic recruitment-derecruitment in acute respiratory distress syndrome (ARDS) patients, as measured by dynamic computed tomography (CT).
