Smartly designed air diffusion ports for exhaled air 360 degree elbow and Tube Swivel Set-it-and-forget-it headgear clips Minimal Contact Points The Quattro FX For Her design creates a mare secure seal without a forehead support system. This innovative approach to design provides the Quattro FX For Her Full Face CPAP Mask user with complete freedom. Freedom that comes from a clear line of sight - read a book, watch TV, or simply enjoy the view. Spring Air Technology The patented Spring Air technology creates a type of 'shock absorber' between the Spring frame and Spring Air cushion. These features coupled with the ergonomic headgear, work together to eliminate the need for a forehead support. In summary, the entire system works to create comfort, while providing a soft, stable mask during sleep. Dual-Wall, Spring Air Cushion The Mirage FX generation of masks uses a revolutionary design that provides comfort and stability. Dual-wall design takes an inner and outer approach to maintaining a seal. The soft inner supportive layer stabilizes the cushion. The outer membrane reduces leaks and pressure points. As air flow increases into the cushion, the outer membrane inflates to surround the nose, as opposed stretching over it. Swing Seal Technique The ResMed Quattro FX For Her Full Face mask uses a new Swing Technique to create the perfect fit. The Swing Seal technique is the result of the Spring Air technology and the dual-wall membrane that surrounds the bridge of your nose. In summary, as the air enters the mask it slowly inflates and adapts to your facial contours. With the straps unattached, simply place the mask at the bridge of the nose. For there, you slowing drop the mask into place on your face. Once is place, simply attach the straps to your comfort. There is not need to re-adjust the mask after this. We have provided a video that walks you through this process. Quattro FX Standard Version ResMed also provides a Standard version of the Quattro FX.
