Pilot Study of the Comparison of the Upper Airway Dynamics of Oronasal vs Nasal Masks With PAP Treatment (Mask_MRI)

Pilot Study of the Comparison of the Upper Airway Dynamics of Oronasal vs Nasal Masks With Positive Airway Pressure Treatment

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).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: All Subjects-Nasal and Oronasal PAP Mask
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.
Subjects will be imaged via MRI wearing a nasal and oronasal PAP mask at 5, 10 and 15 cm H20.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
AHI
Time Frame: through study completion, an average of 1 hour
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.
through study completion, an average of 1 hour

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
MRI of Upper Airway With Opposite PAP Mask
Time Frame: Approximately 1 hour
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.
Approximately 1 hour
