FAQs
1. What is the ResMed AirSense 11 AutoSet and how does it work?
The ResMed AirSense 11 AutoSet is an advanced, user-friendly CPAP (Continuous Positive Airway Pressure) machine that automatically adjusts airflow throughout the night based on your breathing. It’s designed to treat obstructive sleep apnea (OSA)—a condition where the airway collapses or becomes blocked during sleep, leading to disrupted rest and potential health risks.
What sets the AirSense 11 apart is its intelligent algorithm, which tracks your breathing in real time and adjusts air pressure accordingly to keep your airway open. You don’t have to set or guess your optimal pressure—the machine does it for you, ensuring your therapy is always responsive and comfortable.
It also includes features like AutoRamp, which starts therapy at a lower pressure while you fall asleep, then gradually increases it once you’re in a deeper sleep. Expiratory Pressure Relief (EPR) softens the airflow as you exhale, making breathing feel more natural. Together, these features create a therapy experience that is both effective and gentle.
2. What’s included in the Basic AirSense 11 Auto Freedom Plan?
This plan includes everything you need to start CPAP therapy with a focus on simplicity and affordability. You’ll receive the ResMed AirSense 11 AutoSet device, standard (non-heated) tubing, a humidifier tub, and your choice of compatible ResMed mask. These components are essential for effective treatment and daily comfort.
In addition to the equipment, the Basic Care Plan provides remote support. This includes assistance during setup, therapy data downloads on request, and support via email or message. The Basic Plan is ideal for those who are comfortable managing their therapy independently but still want to know help is there when they need it.
3. How do I clean and maintain my AirSense 11 AutoSet?
Regular cleaning is key to keeping your CPAP machine running efficiently and hygienically. Each day, you should empty and rinse the humidifier tub with warm water and allow it to air dry. Wipe down the cushion of your mask with a clean cloth or CPAP wipe to remove facial oils and moisture.
Once a week, you should clean the tubing, full mask assembly, and humidifier tub using warm water and mild, fragrance-free soap. Rinse thoroughly and let all components air dry out of direct sunlight. Never use harsh cleaning agents, bleach, or alcohol.
The machine itself doesn’t require much cleaning—just wipe the exterior with a damp cloth as needed. The air filter at the back of the unit should be checked monthly and replaced every 1 to 6 months depending on dust and usage. These simple steps go a long way in maintaining performance and preventing unwanted odours, blockages, or bacterial growth.
4. How do I know if my AirSense 11 is working properly?
You’ll know the device is working correctly if you feel a consistent, gentle stream of air when the machine is turned on and your mask is on your face. As you breathe, the pressure should adjust smoothly without feeling forceful or erratic.
After each session, the machine displays a basic summary on the touchscreen—showing usage time, mask fit, and humidifier status. A green “smiley face” next to the mask icon means you had a good seal that night.
You can also track your performance using the ResMed myAir app, which gives you a daily sleep score based on key metrics like mask leak, events per hour (AHI), and overall usage. If anything seems off—such as loud noise, poor airflow, or repeated error messages—you can check your tubing and filter or contact support if issues persist.
5. Can I travel with the AirSense 11?
Absolutely. The AirSense 11 AutoSet is compact, lightweight, and travel-ready. It’s approved by the FAA for use during flights and includes Airplane Mode, which disables the wireless signal while still allowing full therapy functionality.
The included power supply supports universal voltage (100–240V), making it suitable for international use—you’ll just need a plug adapter for overseas outlets. For trips where mains power isn’t available, such as camping, you can purchase a compatible CPAP battery separately.
The device also comes with a travel bag to keep everything organized and protected. With a little planning, you can maintain your therapy routine no matter where you go.
6. Can I use tap water in the humidifier?
It’s best not to. Tap water often contains minerals like calcium and magnesium, which can build up in the humidifier tub over time, creating white residue and promoting bacterial growth. These deposits are not only hard to clean but can also damage the tub and affect the quality of humidification.
To avoid this, always use distilled or demineralised water in your humidifier chamber. If you’re travelling and don’t have access to distilled water, you can boil and cool tap water as a temporary backup—but return to distilled water as soon as possible to protect your equipment.
7. What kind of support is included in the Basic Care Plan?
The Basic Care Plan is a streamlined support option designed for users who prefer a self-guided therapy experience. It includes remote setup assistance and access to support via email or messaging. If you ever need your therapy data reviewed or downloaded—for example, for a sleep doctor or licensing body—this can be arranged upon request.
Unlike the more comprehensive Complete Plan, it doesn’t include scheduled consultations or automatic part replacements, but it gives you essential backup when you need clarification or encounter minor issues.
8. How often should I replace parts like the filter, mask cushion, or tubing?
Even with regular cleaning, CPAP components wear out over time and should be replaced to maintain hygiene and performance. As a general rule:
- Air filters should be replaced every 1 to 6 months, depending on air quality.
- Mask cushions last 1 to 3 months before they lose elasticity and start leaking.
- Tubing should be replaced every 6 to 12 months to prevent bacterial buildup and airflow obstruction.
- Humidifier tubs should be replaced every 6 months or sooner if there’s any sign of discoloration, scaling, or damage.
Keeping your equipment fresh reduces the risk of leaks, discomfort, or reduced therapy effectiveness.
9. Is the AirSense 11 compatible with the myAir app?
Yes. The AirSense 11 is designed to work seamlessly with the ResMed myAir app, available for both iOS and Android. Once paired, the app automatically receives your therapy data via wireless connectivity.
Each morning, you’ll see a personalised score out of 100, which reflects your therapy usage, mask fit, AHI, and leak levels. You’ll also get helpful tips and encouragement to keep you motivated. For many users, this daily feedback is an important part of staying engaged and consistent with their therapy.
10. What masks are compatible with the AirSense 11 AutoSet?
The AirSense 11 is compatible with all ResMed CPAP masks, allowing you to choose the style that best fits your sleeping habits and breathing preferences. Whether you prefer a nasal mask like the AirFit N20, a full face mask like the F20, or a minimalist nasal pillows design like the P10, they’ll all work smoothly with the device.
The Basic AirSense 11 Auto Freedom Plan includes your choice of ResMed mask at the time of setup, and you can change masks later if needed. Just make sure to use only genuine ResMed masks to ensure optimal compatibility and therapy performance.
