Obstructive Sleep Apnea, Snoring
Conditions
Brief summary
The purpose of this research study is to test a new approach for treating patients with obstructive sleep apnea and/or snoring. The new nasal device, nastent (NAS: nasal airway stent), appears to be a useful alternative or additive treatment.
Detailed description
The nasal stent basically helps to splint the soft palate open. Subjects have a baseline (diagnostic) sleep study without wearing the device. Subjects are then fitted with the device and then subjects wear the device for at least 7 nights during their sleep while at home. Subjects then return for a repeat in-laboratory sleep study while wearing the device. The primary outcome is to assess the effectiveness of the device by change in the apnea-hypopnea index (number of sleep-related abnormal breathing events per hour of sleep) while wearing the device compared to baseline.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Apnea-Hypopnea Index (AHI) | In-lab sleep study obtained at least 7 nights following use of the device at home | Abnormal breathing events (apneas = complete pauses in oronasal airflow; hypopneas = decreases in oronasal airflow) per hour of sleep. This is measured through polysomnography (sleep study) by a nasal thermistor and oral pressure sensor. |

| Nastent A baseline sleep study is obtained from the subject, without wearing the device. The individual wears the device at home for at least 7 nights, and then returns to the sleep lab for an in-laboratory sleep study while wearing the device.

Outcome results
Primary
Apnea-Hypopnea Index (AHI)
Abnormal breathing events (apneas = complete pauses in oronasal airflow; hypopneas = decreases in oronasal airflow) per hour of sleep. This is measured through polysomnography (sleep study) by a nasal thermistor and oral pressure sensor.
Time frame: In-lab sleep study obtained at least 7 nights following use of the device at home
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| Nastent | Apnea-Hypopnea Index (AHI) | 30.0 events/hour | Standard Deviation 20.3 |
