The purpose of this study is to determine if the performance of the modified AutoSet device is equivalent or better than the existing AutoSet device (VPAP Auto) in the efficacy of the treatment and the subjective comfort.
Obstructive sleep apnea (OSA) is characterised by a partial or complete collapse of the upper airway during sleep. The treatment of choice for OSA is Continuous Positive Airway Pressure (CPAP). CPAP acts as a positive airway splint, delivering a fixed or auto adjusted positive pressure to the upper airway via a tube and mask. The modified device to be assessed in this study will act in a similar way to the existing device, VPAP Auto, but utilizes an improved algorithm which should maintain or enhance the effectiveness of the treatment.

Time frame: One Night On Each Arm, approximately 8 hours each night
Satisfaction of Treatment
Participant's treatment satisfaction in one question: How much did the CPAP disturb your sleep last night? Rating from 0 (a lot) to 10 (not at all) on a Likert Scale
Time frame: One Night On Each Arm, approximately 8 hours each night
Refreshed Feel
Participants rated 0 (not refreshed at all) to 10 (very refreshed) on Likert Scale on one question: How refreshed did you feel this morning?
Time frame: One Night On Each Arm, approximately 8 hours each night
