Material Components for Quattro™ FX Full Face CPAP Mask Spring Frame
Spring Frame: Polycarbonate
Fewer Contact Points
The overall design of the Quattro FX helps to create a secure seal without the aid of a forehead support. Eliminating the forehead support means fewer points of failure and an end to red marks on your forehead. Without a forehead support, you will also enjoy a clear line of sight for viewing television or reading a good book in bed.
Spring Air Technology
Spring Air technology helps to create a suspension-like action between the Spring frame and Spring Air cushion. These two mask parts, along with the contoured crown cap headgear, work together to offer an angular adjustment that makes a forehead support obsolete. The stability of the design helps to distribute pressure evenly around the face, yet reacts to accommodate user movement.
Dual-Wall, Spring Air Cushion
The Mirage series of CPAP masks have endeavored to provide superior cushion design through the incorporation of two cushion layers. The dual-walls consists of an inner, supportive layer that stabilizes the cushion and a softer, outer membrane that reduces the likelihood of leaks and pressure sores. As air flows through the cushion, the outer membrane rolls and inflates around the nose rather than stretching over it.
Swing Seal Technique
Size. Swing. Seal. Those are the simple steps used for fitting the Quattro FX. The Swing Technique is the result of the Spring Air technology and the dual-wall membrane that surrounds the bridge of your nose. As air flows through the mask and into the cushion, the contoured membrane inflates and gently positions the cushion against the face so that it forms a secure seal without the need to over tighten the headgear.
This unique design makes fitting a breeze. With the headgear clips removed, just position the mask at an angle, so that the cushion rests on the middle of the nasal bridge. Then swing the mask down to rest between the bottom lip and chin. Reattach the headgear clips and adjust the side straps for a snug fit.
Where do I find the size?
To find the size of the mask frame, turn the mask upside down. The flat bottom of the mask frame and mask cushion needs to face the user. The size is embossed between the ports cap and the edge of the mask frame. A clear letter will indicate the size of the mask frame.
The size of the full face cushion is located on the flat bottom of the cushion. Turn the mask upside down with the headgear facing away from the user. Located on the bottom silicone flap to the right side of the name of the mask, an embossed clear letter will specify the size of the full face cushion. The letter is larger than the word ResMed and Quattro™ FX.
Quattro and Quattro FX mask frames, cushion clips and cushions are NOT interchangeable. Individual cushions are NOT interchangeable within each mask. The size must correspond for the mask to work properly. For more information visit the Mirage Quattro FX Full Face Mask Cushion and Clip.
Sizing Help The Mirage Quattro sizes DO NOT match up directly with the Quattro FX sizes. The Quattro FX sizes are a bit smaller than the Mirage Quattro sizes. To get a more accurate idea of your size, measure from the top of the bridge of your nose down to the place in between your bottom lip and chin. View the images below to see where on the face to measure. Compare your measurement with the size measurements here:
- Small: 3 9/16"
- Medium: 4"
- Large: 4 3/8"
