Alterations of the beneficial effect of deep inspiration in scleroderma: relationships between lung function and imaging.

2007

<i>Background:</i> It has been postulated that the beneficial effects of deep inspiration are dependent on the magnitude of airway distension by virtue of airway to parenchyma interdependence. <i>Objective:</i> This study was designed to examine whether the changes that occur in pulmonary fibrosis affect the beneficial effect of deep inspiration. <i>Methods:</i> Thirty-one subjects with scleroderma underwent lung volume and diffusion capacity assessment as well as high-resolution computed tomography. To assess the effect of deep inspiration, each subject underwent methacholine provocations in the absence of deep breaths. When the targeted change in lung f…
