About this trial
This is an interventional health services research trial for Obstructive Sleep Apnea (OSA)
Eligibility Criteria
Inclusion Criteria:
- AHI> 30/hr
- 18-75 years of age
Exclusion Criteria:
- History of claustrophobia
- History of pacemaker, nerve stimulator, or any other metal implanted device
Sites / Locations

Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
All Subjects-Nasal and Oronasal PAP Mask
Arm Description
Each subject will be imaged in a dynamic MRI with both a oronasal and nasal mask at pressures of 5, 10, and 15 cm of H2O.
Outcomes
Primary Outcome Measures
AHI
The AHI is the number of apneas or hypopneas recorded during the study per hour of sleep. It is generally expressed as the number of events per hour.
Secondary Outcome Measures
MRI of Upper Airway With Opposite PAP Mask
MRI will be used to obtain airway measurements and the position of soft tissue elements of the oropharyngeal airway will be evaluated while positive airway pressure in introduced through the opposite mask type.

5. Study Description
Brief Summary
Our group has recently found that the choice of positive airway pressure mask can significantly affect the pressure required to adequately treat sleep disordered breathing. The goal of this study is to visualize the upper airway in the retropalatal and retroglossal region while using both oronasal and nasal masks with CPAP in order to investigate differences in upper airway dynamics that may occur between these two mask types.
Detailed Description
It is known that oronasal masks are not as effective at opening the upper airway compared to nasal only continuous positive airway pressure (CPAP) masks in patients with sleep-disordered breathing. However, the physiological mechanism for this difference in efficacy is not known; although, it has been hypothesized to involve the retroglossal and/or retropalatal region of the upper airway. The objective of this study was to investigate differences in retroglossal and retropalatal anterior-posterior space with the use of oronasal vs. nasal CPAP masks using real-time cine magnetic resonance imaging (cMRI).
