Humidification

Q. Why do the AirSense™ 10 and AirCurve™ 10 devices come with the HumidAir™ heated humidifier built-in?

A. During therapy, the air delivered may overwhelm the body’s ability to naturally add heat and moisture. This  can lead to a sore, dry throat; nasal congestion; or a runny nose. Heated humidification has been shown to help minimise the side effects associated with positive airway pressure therapy, and help make it a more comfortable experience.1 Given the positive impact heated humidification can have, ResMed has built the humidifier into the sleep apnea machine to make it easier for therapy users to receive these benefits.

Q. Can I use my sleep apnea machine without the HumidAir™ heated humidifier?

A. If you don’t want to use the humidifier, your therapy machine will still work, but you’ll need to turn humidification off in the My Options menu. If you want to use the machine with the humidifier removed, you’ll need to insert a side cover into the machine.

Q. How do I know if my humidifier is working?

A. Icons are displayed on the sleep apnea machine screen to indicate when the humidifier is heating up or cooling down. The Sleep Report option on your AirSense™ 10 or AirCurve™ 10 device will indicate that your humidifier is working properly with a smiley face icon. See your user guide for a detailed list of icons and their descriptions.

Q. What does the humidifier smiley face in Sleep Report mean?

A. This means that the humidifier is working as intended for the current settings, and that there is no hardware fault.

Q. What happens if the water tub runs out of water?

A. Your machine will function normally and safely without water in the tub, but it will no longer provide humidification.

Q. What is warm-up mode?

A. The water in your HumidAir™ heated humidifier will rise to a target temperature of 40°C over 20 minutes. The machine then holds this temperature for a further 10 minutes, ready for therapy to start. If therapy does not start in that time, the machine will automatically enter cool-down mode, where it will blow a small amount of air for around 20 minutes to stop condensation forming in the machine.
