A Development Study to Evaluate a Nasal Mask for the Treatment of Obstructive Sleep Apnea

This investigation is designed to evaluate the comfort, ease of use and performance of a trial nasal mask for the treatment of Obstructive Sleep Apnea (OSA) in the home environment.

The investigation is a prospective, non-randomized, non-blinded study. Up to 45 OSA patients who currently use a nasal or nasal pillows mask will be recruited

This study will involve a baseline (Visit One) data gathering with the participant's PAP therapy and their usual mask. This will be followed by the participants being fitted with the trial nasal mask for use in-home (Visit Two). The participant then will come in to return the mask (Visit Three) and give feedback on their experience using the mask in home in the form of a structured interview during Visit Three. The maximum amount of time the participants will be exposed to the trial mask in-home will be 14 ± 5 days from Visit Two.

The mask and CPAP (if used from the loan research pool) will be returned to the institution at the conclusion of the trial and participant will return to their usual mask and therapy device for the treatment of Obstructive Sleep Apnea.

Neither the investigators nor the participants will be blinded to the study.
