The ResMed Mirage Vista nasal mask is the unobtrusive choice for sleep apnea patients. This mask offers the trusted performance of our Mirage cushion technology in an unobtrusive, streamlined frame design that allows users to read themselves to sleep without having to wake up and start therapy later. Key features Flexible. One-snap elbow allows the mask to remain in place while detaching the tubing, and it swivels 360° to minimize leak and reduce headgear tension. Convenient. The "set it and forget it" headgear comes preassembled, and once fit, it stays fit. Easy to assemble. Quick Connect Cushion eliminates the need for a cushion clip and simplifies reassembly. Comfortable. Mirage cushion technology provides optimal comfort and stability, while the Breath-O-Prene™ headgear draws moisture away from skin and allows air to circulate. Adaptable. Fit Angle Selector allows precise fitting with five symmetrical positions and twenty asymmetrical positions for greater stability, so patients can achieve the best possible fit. Unobtrusive. The streamlined headgear design eliminates forehead support and allows users to wear eyeglasses.
