This bundle pairs the ResMed AirCurve 11 VAuto BiPAP machine with the AirTouch N20 nasal mask, so both arrive together already matched for bilevel therapy. This is a BiPAP, not a CPAP: it delivers two pressures, a higher IPAP as you breathe in and a lower EPAP as you breathe out, instead of one fixed or auto-adjusting pressure all night. It is built for anyone who has been prescribed bilevel therapy, whether because a single CPAP pressure was hard to tolerate or because a sleep physician determined bilevel support is the better fit for their airway. This is factual product information, not medical advice; your prescribing clinician determines which therapy and settings are right for you. In the box: a ResMed AirCurve 11 VAuto BiPAP machine with the built-in HumidAir humidifier and standard tubing, an AirTouch N20 nasal mask with frame, memory foam cushion in your chosen size, and magnetic headgear, and a ResMed standard filter. Ordering the machine and mask together means one delivery and no guessing which mask fits a bilevel machine. A bilevel prescription is required to purchase this bundle. The AirCurve 11 runs VAuto mode, auto-adjusting IPAP and EPAP between 4 and 25 cm H2O with 0 to 10 cm H2O of pressure support as your breathing changes through the night, and it connects over built-in cellular and Bluetooth to the myAir app. The AirTouch N20 seals under the nose with an UltraSoft memory foam cushion instead of silicone, and its headgear uses magnetic clips for a quick, one-handed fit.
