Treatment for Obstructive Sleep Apnea

Brief summary

To study the effects of two combination therapies for patients with obstructive sleep apnea (OSA) who have been both intolerant to Positive Airway Pressure (PAP) therapy and sub-therapeutic to oral appliance therapy. Hypothesis 1\. There is a difference between Continuous Positive Airway Pressure (CPAP) vs CPAP/Oral Appliance (OA) connect vs CPAP/OA disconnected in terms of: 1. Apnea Hypopnea Index (AHI) reduction 2. Amount of side effects 3. Amount of Leaks 4. Hours of use (compliance) 5. CPAP pressure 2\. There is a difference between connected and disconnected for the following symptoms: 1. Epworth sleepiness Scale (ESS) 2. Functional Outcomes of Sleep Questionnaire (FOSQ) 3. Side effects Study Design - randomized prospective parallel

Design outcomes

Primary

MeasureTime frameDescription
Apnea-Hypopnea Index2 monthsEpisodes per hour that the patient experiences apneas and/or hypopneas
PAP Pressure2 monthsThe pressure required to treat the patient successfully
Leaks2 monthsThe Liters/Minute of leaking of the PAP machine
Hours of Use2 monthsThe average hours of use per night of each of the combination therapies
Epworth Sleepiness Scale (ESS)2 monthsThe ESS is a self-administered questionnaire with 8 questions. The score can range from 0 to 24. The higher the ESS score, the higher that person's average sleep propensity in daily life.
Functional Outcomes Sleep Questionnaire (FOSQ)2 monthsFOSQ is a disease specific quality of life questionnaire to determine how sleepiness interferes one's quality of life. The total score range from 5 to 20 (10 questions, 1-4 points per each). The lower values represent a worse quality of life.
Intolerance Questionnaire2 monthsThis questionnaire consists of 4 questions to determine the frequency of 4 typical side-effects from positive airway pressure therapy. The score ranges from 0 to 16 (4 questions, 0-4 points per each). The higher value represent worse side effects.
