December 8, 2015 updated by: Jane Winantea, University Hospital, Essen
In this study the investigators examine the glottic width and the respiratory flow at rest in patients with various lung disease. The investigators postulated that a positive expiratory pressure is created through the narrowing of the glottic width in patients with hyperinflation.
