Welcome to my ResMed AirCurve 11 ASV Review.
When I was diagnosed with obstructive sleep apnea, my world changed overnight. Like most of you, I started researching CPAP machines, masks, hoses — everything that could help me sleep again. Along that journey, I discovered something fascinating: not all apnea is the same, and not all machines treat it the same way.
That’s how I first came across ASV therapy — adaptive servo-ventilation — designed for people whose apnea isn’t caused by a blocked airway, but by the brain’s irregular breathing signals. These are known as central and complex mixed sleep apnea.
Now, I don’t personally use ASV (my apnea is obstructive), but I’ve spent years studying sleep therapy technology for readers of this site. And if you’ve been prescribed ASV — or you’re wondering whether the ResMed AirCurve 11 ASV is worth upgrading to — this review is for you.
What Is ASV and Who Needs It?
Before diving into the machine, let’s clear up what ASV actually does.
ASV (Adaptive Servo-Ventilation) is a specialized PAP therapy used to treat central sleep apnea and complex sleep apnea. These are conditions where your brain intermittently “forgets” to send the signal to breathe. An ASV machine can also be used to treat Cheyne-Stokes Respiration.

In contrast, CPAP treats obstructive sleep apnea (OSA), where the airway collapses.
So, if your sleep study showed central or mixed apneas — or if CPAP didn’t fix your breathing issues — your doctor might prescribe ASV.

What Makes the ResMed AirCurve 11 ASV Different?
The AirCurve 11 ASV is the newest adaptive servo-ventilation machine from ResMed, replacing the older AirCurve 10 ASV.
Here’s the key idea: this machine constantly monitors your breathing in real time and adjusts pressure support with every breath. When your body pauses or slows its rhythm, the AirCurve steps in, gently increasing pressure to keep your breathing stable.
ResMed calls this their PaceWave™ ASV algorithm, and it’s a big part of why this machine has become the go-to model for complex sleep apnea treatment.
Notable upgrades from the AirCurve 10
- Smarter algorithm – improved response to breath-by-breath variability.
- Wi-Fi + Bluetooth connectivity – replaces 3G (which is being phased out).
- myAir app + AirView integration – lets you and your doctor track progress remotely.
- Quieter operation – slightly lower decibel level than the previous version.
- Modern interface – touchscreen display, cleaner menus, easier navigation.
- OTA (Over-the-Air) firmware updates – software improvements without hardware swaps.
If you’ve ever owned a ResMed AirSense 11 (the CPAP version), the look and interface will feel familiar — that’s because ResMed designed the AirCurve 11 to match the same modern aesthetic and ecosystem.
How to Set Up and Use the AirCurve 11 ASV
If you’ve never used an ASV machine before, setup can feel intimidating, but ResMed has made it surprisingly straightforward. This latest model is almost plug-and-play!
- Connect the components: attach your tubing, humidifier chamber, and mask.
- Add distilled water: fill the integrated humidifier (never use tap water).
- Power on and start therapy: the system auto-calibrates pressure support based on your breathing.
- Sync with myAir: download the app to view daily reports and tips.
- Stay connected with your doctor: through AirView, clinicians can monitor data remotely.
That last part is a game-changer. For new ASV users, being able to adjust settings remotely means fewer office visits and faster fine-tuning of comfort levels.
Tip: If you’re switching from CPAP or BiPAP, give your body at least 1–2 weeks to adjust. ASV feels different because the pressure changes more dynamically — but it becomes second nature over time.
AirCurve 11 ASV vs AirCurve 10 ASV
If you’re upgrading or choosing between the two, here’s a side-by-side breakdown:
| Feature | AirCurve 10 ASV | AirCurve 11 ASV |
|---|---|---|
| Algorithm | Older ASV algorithm | New PaceWave™ ASV |
| Connectivity | 3G (obsolete in many areas) | Wi-Fi + Bluetooth |
| Noise Level | ~27 dBA | ~26 dBA |
| Display | Button + LCD | Touchscreen |
| Design | Bulkier | Sleeker, smaller footprint |
| App Support | Limited | Full myAir + AirView |
| Firmware Updates | None | Over-the-air (OTA) capable |
In short, therapy performance is equally effective, but the AirCurve 11 wins on connectivity, usability, and future-proofing.

Who Should (and Shouldn’t) Buy the AirCurve 11 ASV
Let’s talk about fit — because ASV isn’t for everyone.
The AirCurve 11 ASV is right for you if:
- You’ve been diagnosed with central or complex sleep apnea.
- You’re upgrading from an older AirCurve 10 ASV.
- You want smart connectivity and remote support.
- You prefer a quieter, more compact design.
It’s not necessary if:
- You have purely obstructive sleep apnea (OSA) — CPAP or BiPAP is the right treatment for that.
- You don’t have a prescription for ASV (it’s a specialized therapy).
If you’re unsure which category you fall into, talk to your sleep doctor. They’ll review your sleep study and determine whether ASV is appropriate.
Cost & Where to Buy
The ResMed AirCurve 11 ASV is a premium device, and it does require a prescription. I have teamed up with Sleep Doctor, who are the leading suppliers of CPAP equipment online. If you follow the link on the button below, they can help you with your ASV machine needs.
Customizing Comfort and Routine
Once you’ve started ASV therapy, personalization is everything.
Some users find the pressure transitions too noticeable at first — especially if switching from CPAP — but that’s where the AirCurve 11 shines.
- Climate Control Auto adjusts humidity and tube temperature automatically.
- Mask Fit Check ensures leaks are sealed before therapy begins.
- Ramp Time can be fine-tuned so the machine eases into pressure support gradually.
I recommend journaling your first two weeks — note how rested you feel, your energy levels, and any discomfort. If something feels off, your doctor can view your data via AirView and make remote tweaks almost instantly.
FAQ
Q: Can the AirCurve 11 ASV treat obstructive sleep apnea?
Not directly. While it can handle mixed events, it’s primarily designed for central and complex sleep apnea. If your sleep study shows only OSA, a ResMed AirSense 11 CPAP may be a better fit.
Q: Is the AirCurve 11 ASV loud?
Not at all. At around 26 dBA, it’s whisper-quiet — about the same as rustling leaves.
Q: Does it require a professional setup?
Yes. ASV settings are prescription-based, so your provider or DME will configure it initially.
Q: Can it connect to my phone?
Yes! It syncs with the myAir app for daily feedback and AirView for clinician monitoring.
Q: How long does the AirCurve 11 ASV last?
Typically 5–7 years with regular cleaning and proper care.
Conclusion
The ResMed AirCurve 11 ASV isn’t just an incremental update — it’s the most advanced ASV device ResMed has ever made.
Even though I personally use CPAP for obstructive apnea, I research these machines because technology like this represents the future of personalized sleep therapy. If your doctor recommends ASV, the AirCurve 11 offers the best blend of intelligence, connectivity, and quiet comfort on the market today.
It’s smart enough to adapt to every breath — and that kind of precision can change everything for someone living with complex sleep apnea.
