A: How to access your comfort settings on the AirSense 11: On your AirSense 11 machine, use the touchscreen to go to My Options to see your current settings. From here, you can personalize your options.

Humidity Level

The humidifier moistens the air and is designed to make your therapy more comfortable.

If you have a ClimateLineAir™ heated tube, all you have to do is plug it in and press Start. Note: ClimateLineAir heated tubing is required to use Climate Control Auto. You can also manually set the Humidity Level to Off or between 1 and 8, where 1 is the lowest humidity setting and 8 is the highest humidity setting. If you’re getting a dry nose or mouth, turn up the humidity. If you’re getting any moisture in your mask, turn down the humidity. How to adjust humidity: In My Options, select Humidity Level. Scroll and select the desired humidity level.

Ramp Time

Ramp Time is the period during which the pressure increases from a low start airflow pressure to your prescribed treatment pressure. You can set your Ramp Time to Off, from 5 to 45 minutes or Auto. When Ramp Time is set to Auto, the device will detect when you have fallen asleep and then gradually increase to the prescribed treatment pressure.
