Assessment of the Performance of a New Reduced Noise Mask Vent

Clinical Trial of a New Mask Vent, Designed to Reduce Noise of Mask Venting

As continuous positive airway pressure is the treatment of choice for OSA, a mask is vital in ensuring the effectiveness of therapy delivery. The study will evaluate the performance and usability of the new mask vent. This is done by comparing the apnea-hypopnea index (AHI) of patients, who will apply 2 different washing procedures to the new mask, at the end of the study and their baseline data obtained at the beginning of the study.The study will also assess the breathing comfort as well as obtaining subjective data on the usability of the new mask vent system.
