Mechanisms of Pharyngeal Collapse in Sleep Apnea, Study C

NCT01738022 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

Last updated 2019-07-11

No results posted yet for this study

Summary

In obstructive sleep apnea (OSA), the upper airway recurrently closes during sleep. The mechanisms that lead to airway closure are not completely understood. Models to study mechanisms of airway collapse have been proposed. However, these models have not been tested in the human upper airway. Gas density and viscosity are different gas properties that influence upper airway collapse and are variables of different models. In this study, subjects will breathe gas mixtures of different densities and viscosities for brief periods of time in order to test those models.
