Effect of Added Varnum Mouthpiece on Pharyngeal Collapsibility and Sleep Apnea Severity in Mouth Breathers.

David Andrew Wellman·interventional·Posted Apr 14, 2016·Updated Apr 4, 2022

In Brief

A clinical study evaluating Varnum mouthpiece for Obstructive Sleep Apnea. Completed, enrolled 26 participants across 1 site.

Detailed Summary

Test the effect of added a single-use Varnum mouthpiece on pharyngeal collapsibility and obstructive sleep apnea (OSA) severity in patients who identify themselves as mouth breathers. Research indicates that nasal breathing not only may improve sleep apnea but it also increases circulation, blood oxygen, and carbon dioxide levels, slows the breathing rate, and improves overall lung volumes. Thus, the investigators will test whether a single-use Varnum mouthpiece can improve pharyngeal collapsibility and OSA severity in mouth breathers.
