ResMed AirSense 11 AutoSet CPAP Machine

The ResMed AirSense 11 delivers peaceful, whisper-quiet therapy at just 27 decibels. Sound levels can be affected by your mask fit and hose connection, but with proper setup, most users find their bed partners don't even notice it running. For the quietest experience, we recommend ensuring your mask fits properly and checking that your humidifier and hose is securely connected.

Yes, the AirSense 11 AutoSet CPAP senses your breathing patterns and adjusts therapy pressure throughout the night. It offers three therapy modes to match your needs:

1. AutoSet: Automatically responds to sleep events, providing exactly the pressure you need.
2. AutoSet for Her: Designed specifically for women, featuring more gradual pressure changes.
3. CPAP: Maintains one consistent pressure level throughout the night.
   

Your comfort comes first, with features like AutoRamp™ that starts at a lower pressure until you fall asleep, and EPR™ that makes breathing out more natural by lowering pressure when you exhale.

If you're sensitive to pressure changes, AutoSet Response lets you choose gentler adjustments. Monitor how your device adapts to your needs using the myAir™ app.

Upgrading to a heated hose can help provide a more consistent therapy experience regardless of seasonal changes or location. If you find yourself traveling to a different climate, a heated hose can help you maintain the same therapy you had at home.

If you experience the collection of condensation in your CPAP hose that drips down onto your face and wakes you up, also known as CPAP rainout, a heated hose can help prevent condensation buildup, allowing you to sleep through the night.

With a ClimateLineAir 11 Heated Tube, you’ll also be able to utilize the AirSense 11’s auto climate control settings, which automatically detect the ambient room temperature and supply the optimal humidification for your sleep setting.

You may want one if you:

- Experience dry mouth or throat
- Notice water droplets in your tube
- Use humidification regularly
- Live in a cold or dry climate

You might not need one if you:

- Live in a humid climate
- Don't use the humidifier
- Keep your bedroom warm
- Are comfortable with your current setup

Many of our customers find the heated hose adds noticeable comfort to their therapy, particularly in winter. If cost is a concern, a CPAP hose cover provides similar benefits at a lower price point.
