Learn More About the Rio II Nasal Pillow CPAP Mask With Headgear: Unique Rotating Ball and Socket Swivel for Active Sleepers Minimal Design with Just Two Adjustment Points Open Line of Sight Upgraded Frame and Headgear Active Sleepers Can Comfortably Change Sleeping Positions The Rio II features a unique rotating ball and socket swivel and an angled nasal pillow reservoir to offer true freedom of movement, so you can flip from your side to your stomach and back again, all while you sleep. The angle of the pillows reservoir can also be adjusted for a better fit and greater comfort. Two Simple Adjustment Points to Find Your Ideal Fit The Rio II features only two adjustment points: an adjustable split-back strap and two velcro fasteners. The split back strap allows you to achieve a tighter fit or a looser fit while the velcro fasteners create an added layer of adjustment for your comfort. The Rio II comes equipped with three sets of nasal pillows, to ensure the silky soft ergonomic cushion puts the exact right amount of pressure on your face. Open Line of Sight to Maintain Your Nightly Routine The minimal, ergonomic design is beneficial for those who wear glasses, experience claustrophobia, or enjoy reading or watching T.V. before bed. Enhanced Comfort With Upgraded Frame and Headgear The Rio II’s frame and headgear provide a lighter and more flexible fit with added stability thanks to the new cheek pads. Fitting Your Rio II Nasal Pillow Mask Thread the two side straps of the headgear through the gaps in panels separately, then fold back over to secure. Put the headgear over your head by holding the back strap and stretching it around the back of your head. The top strap should sit comfortably on the top of your head. Adjust each end of the side strap evenly until the interface sits comfortably just under the nose. Reattach the fastening tabs. Move the mask away from your face then place it back to get a comfortable fit. Ensure the nasal pillows fit securely into your nostrils with both pillows positioned upright. Finally, connect the end of the mask short tube into your CPAP hose. Your interface is now fitted and ready to use. Please Note: If you feel an air leak, readjust the angle of the nasal pillows to get a better seal. If you are unable to resolve any leaks, you may need an alternative nasal pillow size. RII1000
