Study of Nasal Airflow Pressure Optimization to Resolve Excessive Snoring (SNORE)

Inclusion Criteria:

• Subject is > 18 years of age.
• Subject is willing and able to provide written Informed Consent using a Patient Information and Consent form that has been reviewed and approved by a governing Institutional Review Board (IRB).
• Subject has a history of habitual snoring (almost every night or every night for at least 30% of the night) as determined by the subject or a bed-partner.
• Subject has been pre-screened and demonstrates no excess daytime sleepiness on an Epworth Questionnaire (an assessment of daytime sleepiness; high number = greater sleepiness) score of less than 11, no history of witnessed apneas or nocturnal gasping/choking episodes and a body mass index (BMI) ≤ 35.

Inclusion Criteria for treatment trials (Nights 2 and 3):

• Subject meets Inclusion Criteria for the Baseline Trial (criteria a-d above)
• The subject has snoring intensity that exceeds 40 dBA during ≥30% of the respiratory efforts during sleep time on the baseline study night.

Exclusion Criteria:

• Subject has been diagnosed with COPD (Chronic Obstructive Pulmonary Disease), such as asthma, emphysema or chronic bronchitis.
• Subject has a history of heart disease, heart attack or stroke.
• Subject has uncontrolled or poorly controlled hypertension.
• Subject has been diagnosed with Obstructive Sleep Apnea (OSA), defined as an apnea hypopnea index (AHI) ≥ 5/hr in the presence of excessive sleepiness (an Epworth score ≥ 11) or AHI ≥15/hr when there is no evidence of excessive daytime sleepiness (an Epworth score ≤ 10).
• Subject is currently participating in another clinical study for which follow-up is ongoing.
