Performance of the Tasman Continuous Positive Airway Pressure (CPAP) System

Assessment of the performance of the Tasman CPAP system in treating obstructive sleep apnea. The purpose of this study is to (1) evaluate the performance of this system in the efficacy of the treatment in comparison to S8 Escape, and (2) to evaluate the performance of the Tasman device via subjective assessment of comfort and ease of breathing compared to the participant's current CPAP device.

Obstructive Sleep Apnoea (OSA) is a condition characterised by 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 positive airway pressure to the upper airway via a tube and mask. The mask is attached to the participant's nose via head straps. The type of mask used is dependent upon participant choice and comfort and the mask that provides the best fit. Some participants stop using CPAP therapy finding it difficult to tolerate due to leak issues or discomfort from their nasal mask. Another frequent concern is mask dislodgment while sleeping causing leaks and consequently waking the patient up. The purpose of this study is to evaluate the performance of the Tasman CPAP system via objective and subjective assessment of comfort and ease of breathing compared to the participant's current CPAP device. Aim To determine if the efficacy of the treatment is clinically equivalent to or better than the predicate device (S8 Escape) To evaluate the performance of the Tasman CPAP system in terms of comfort of breathing and general ease of use

Participants will trial the Tasman CPAP system for a duration of 1 week in place of their current CPAP system.

To determine if the efficacy of the treatment is clinically equivalent to or better than the predicate device (S8 Escape)
