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

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.
