Noise Level

The ResMed AirSense is known for its quiet operation, with a noise level of around 27dBa. This is comparable to a soft whisper or a gentle hum.


The ResMed AirSense™ 10/11, a CPAP device equipped with new technology designed to make starting therapy, acclimating and adhering to it easier and more convenient for your patients. The AirSense devices are compact and have a built-in humidification chamber that allows for easy portability. 


To access the Climate Control Manual mode, users can follow these steps from the machine's Home screen: Select "My Options," then choose "Climate Ctrl." Change the default setting from "Auto" to "Manual." Next, select "Humidity Level" and adjust the dial to set the desired humidity level (ranging from 1 to 8, with the default setting at 4). Similarly, choose "Tube Temp" and turn the dial to select the most comfortable temperature for the ClimateLine/ClimateLineAir heated tube (with a range of 60–86⁰F, defaulting to 81⁰F). For more detailed instructions, refer to the ClimateLineAir user guide.

For S9 users, the Climate Control Manual setting must be activated by their equipment supplier. From the Home screen, to adjust humidity, turn the dial to highlight the water drop icon; push the dial, turning the background yellow. Then, turn the dial to set the humidity level (ranging from 1 to 6, with the default setting at 3). Push the dial once more to confirm the new humidity level. To set the tube temperature, turn the dial to highlight the thermometer icon; push the dial to turn the background yellow. Then, turn the dial to select the desired ClimateLine/ClimateLineAir tube temperature (ranging from 60–86⁰F, defaulting to 80⁰F). Push the dial again to confirm the new temperature.

Determining when to adjust humidity versus temperature is a key consideration. Many patients find cooler air more comfortable for sleeping, particularly new CPAP users, those using a full face CPAP mask, and women experiencing hot flashes at bedtime. However, warmer air provides optimal humidity and reduces nasal irritation. Increasing humidity can be beneficial if dry air leads to waking up with a dry mouth, a common concern for 40% of CPAP users. Gradually adjusting humidity and temperature levels can be done one notch at a time. If maximum levels are reached and dryness persists, consulting with the equipment supplier and doctor about potential causes, such as mask leak or medications, is advisable. Additionally, checking for mask leaks if the humidifier's water chamber is consistently empty is recommended.

If dryness persists despite increased humidity, consider a slight rise in tube temperature (1–2⁰F) to assess comfort levels. Empowering patients to make these real-time adjustments offers peace of mind to many and promotes better sleep therapy. As always, consulting with a doctor or equipment supplier before modifying treatment settings is essential.
