A total of 216 patients will be randomized into a partially single blind, randomized, parallel-arm trial to determine whether the ICON™ AT with SensAwake™ and ThermoSmart™ can improve therapy adherence when compared to standard care with a fixed pressure Continuous Positive Airway Pressure (CPAP) device and compared to a less aesthetically pleasing CPAP device without technologies (AutoCPAP, SensAwake™, ThermoSmart™) in patients previously diagnosed with moderate-severe obstructive sleep apnea (OSA).

Primary Outcome Measures:
  • Adherence with treatment per night averaged over total time period measured via internal software on the device and reported on using InfoSmart™ software. [ Time Frame: On day 90 after randomization ]

Secondary Outcome Measures:
  • Adherence (hours of usage per night) and acceptance (number of drop-outs). Complaints during follow up calls and visit. [ Time Frame: On day 90 after randomization ]

Ages Eligible for Study:   18 Years to 70 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Aged 18-70 years with moderate-to-severe OSA (Apnea Hypopnea Index equal to or greater than 10 per hour).
  • Successful titration Polysomnography (PSG).
  • Fluency in both written and spoken English.

Exclusion Criteria:

  • Participants prescribed and fitted with any PAP device in the past 2 years.
  • Contraindicated for CPAP or AutoCPAP therapy.
  • Any known factor or disease that might interfere with treatment adherence, study conduct or interpretation of the results such as severe psychiatric disease, history of non adherence to medical regimens, or unwillingness to comply with study requirements as determined by the principal investigator.
  • Other significant sleep disorder(s) that would interfere with their ability to wear CPAP as determined by the principal investigator.
  • Previous surgery for OSA or snoring or any surgery of the mouth, nose, sinuses or airways.
  • If SensAwake™ or ThermoSmart™ was disabled on the treatment arm (or conversely) during the study protocol.
  • If participants are required, by the nature of their employment, to comply with therapy. For example truck drivers or airline pilots.
  • If the physician objects to their patient taking part in the study.
