This pilot study is being done to determine if the nasopharyngeal airway obstructive sleep apnea (NPA-OSA) device can be used in the treatment of OSA in adults. The researchers think that the NPA-OSA device will reduce the number of apneas.

nasopharyngeal airway obstructive sleep apnea (NPA-OSA) device
DeviceThe NPA-OSA is a flexible, medical-grade silicone, tube-like device that is self-inserted into the user's nasopharyngeal airway through one nostril prior to sleep and worn throughout the night to reduce or alleviate snoring and obstructive sleep apnea.
Change in severity of apnea hypopnea index (AHI)
The AHI is calculated by dividing the number of apnea events by the number of hours of sleep.
