Quick answer: The ResMed AirCurve 11 ASV is the next-generation adaptive servo-ventilation (ASV) device, built on the newer Air11 platform, with a built-in HumidAir 11 humidifier (part 39012). ASV is a specialized bilevel therapy that adjusts pressure support breath by breath — prescribed for specific forms of central and mixed sleep apnea and periodic breathing, not for ordinary obstructive sleep apnea. It is a prescription device with important clinical contraindications, prescribed and titrated only by a physician. HumidAir 11 humidification is built in.
⚠️ ASV is not a standard CPAP or BiPAP. It is prescribed only for specific conditions and has important safety contraindications (see below). Do not use ASV therapy, or change any settings, except exactly as prescribed by your physician.

About this device
Adaptive servo-ventilation (ASV) is a form of bilevel therapy designed for breathing patterns that a fixed pressure can't manage well — particularly central sleep apnea, mixed apnea, and periodic (Cheyne-Stokes) breathing, where the drive to breathe itself varies. Rather than holding a set pressure, ASV continuously monitors your breathing and adjusts pressure support breath by breath — more support when breathing weakens, less when it normalizes — to smooth out the pattern.
The AirCurve 11 ASV brings this therapy to ResMed's newer Air11 platform — the generation that also includes the AirSense 11 CPAP — with its updated interface and features and the HumidAir 11 humidifier. It remains a clinician-prescribed and clinician-titrated therapy for specific confirmed diagnoses, fundamentally different from CPAP or standard BiPAP.
Because it's an Air11-generation device, it uses Air11-specific consumables — HumidAir 11 tub, Air11 filters, ClimateLineAir 11 tubing — which are not interchangeable with Air10 parts.
Important: ASV contraindications & safety
ASV therapy has a well-established contraindication: it is generally not appropriate for patients with symptomatic chronic heart failure with a reduced ejection fraction (low LVEF), based on clinical trial findings. This is one reason ASV must only ever be prescribed and set up by a physician who has confirmed it's appropriate for you.
- Use ASV only as prescribed by your physician, for the diagnosis it was prescribed for.
- Do not adjust pressures, modes, or settings yourself.
- If your health changes (especially heart or cardiac status), contact your physician.
- This device is not a substitute for the clinical monitoring your care team advises.

Frequently asked questions
What is ASV? Adaptive servo-ventilation — a bilevel therapy that adjusts pressure support breath by breath to stabilize irregular breathing patterns, prescribed for specific central/mixed apnea and periodic breathing.
Is this a CPAP? No. ASV is a specialized therapy different from CPAP and standard BiPAP, prescribed only for particular diagnoses and titrated by a physician.
How is it different from the AirCurve 10 ASV? It's the same ASV therapy on ResMed's newer Air11 platform, with the updated interface and the HumidAir 11 humidifier. It uses Air11-specific consumables.
Will my Air10 tub, filters, or ClimateLineAir fit? No — this is an Air11-generation device and uses Air11-specific consumables (HumidAir 11 tub, Air11 filters, ClimateLineAir 11), which are not interchangeable with Air10 parts.
Is the humidifier included? Yes — the HumidAir 11 heated humidifier is built in, with a water tub.
Who should not use ASV? ASV is generally contraindicated in symptomatic chronic heart failure with a reduced ejection fraction. Only a physician can determine whether ASV is appropriate for you.
Do I need a prescription? Yes — a prescription is required, and the device is set up and titrated by your physician for your specific diagnosis.
Can you help with insurance? We can help with insurance-related purchases through our affiliated service — contact us at (718) 735-3400 and we'll walk you through the options.
How is it delivered? We offer local pickup and delivery in Brooklyn and across NYC, plus USPS shipping throughout the continental U.S. A valid prescription is required before dispensing.
This is a prescription medical device for a specialized therapy. ASV must be prescribed, set up, and titrated by a physician for a confirmed diagnosis, and has important contraindications — including symptomatic chronic heart failure with reduced ejection fraction. Do not use ASV therapy or change settings except exactly as prescribed. Follow the ResMed user guide and your physician's instructions.
