AirCurve 11 VAuto with HumidAir 11 and ClimateLineAir 11 tube

The ResMed AirCurve 11 VAuto is a bilevel machine for sleep apnea that lowers the pressure each time you breathe out. For people who find CPAP hard to exhale against, that difference can make therapy easier to stick with, and the pressures still adjust to you through the night.

Day to day, it's simple to live with. A touchscreen shows last night's hours and mask seal, and its hum is soft enough for a shared bedroom. The humidifier and heated tube warm the air, and myAir can walk you through setup if you'd like help.

Key features:

• Battery and power: There's no ResMed battery for Air11 machines, so plan on a wall outlet, or the DC converter in a car or RV.
• Mask leak: ResMed's Vsync keeps the machine in step with your breathing when air escapes around your mask or through your mouth.
• Mask Fit: A quick check on the screen tells you whether your mask is sealing well or needs a small adjustment before bed.
• Care Check-In: During your first month, short questions about getting used to bilevel therapy appear, followed by tips that match your answers.
• Automatic reporting: Your care provider receives each night's therapy data over the machine's own cellular link, with nothing for you to download or mail.
• Built for Canada: ResMed builds this version for the Canadian market, licensed by Health Canada and boxed with the heated tube and standard tub.

The AirCurve 11 VAuto suits people whose prescriber has moved them from CPAP to bilevel, or who need higher pressures and want exhaling to feel gentler. If one steady pressure works well for you, the AirSense 11 shares this machine's design and parts.

Note: Tubs and heated tubes from the AirCurve 10 won't work here. Pair the machine with HumidAir 11 tubs and a ClimateLineAir 11 heated tube, or any non-heated SlimLine or standard tube.
