Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
