After therapy has stopped, your device will blow a small amount of air to avoid condensation in the device and air tube. This will stop automatically after 20 minutes.

If the air pressure feels too high when you start therapy, it might help to select the device's AutoRamp™ setting. This will allow it to deliver a low start pressure to help you fall asleep with ease. Then, using its sleep onset detection capability, it will comfortably start ramping up to your prescribed pressure the moment it detects you’ve fallen asleep – giving you the therapy you need, the moment you need it. It may also help to enable expiratory pressure relief (EPR™). EPR gently lowers the pressure delivered to you when you exhale – making it easier to breathe out against the air pressure.

Ramp may be in progress. Wait for the air pressure to build up, or turn the Ramp feature off. Humidification

When used with the ClimateLineAir™ heated tube, the AirSense™ 10 and AirCurve™ 10 devices are pre-set to automatically deliver the optimal temperature and humidity thanks to Climate Control Auto. If you are using a ClimateLineAir heated tube and still experiencing uncomfortable side effects, enable Climate Control Manual and increase the humidity. If the air becomes too humid and you get condensation, try increasing the temperature. Refer to your user guide for more information.

Air may be escaping through your mouth while you sleep. If you are using a nasal mask or nasal pillows, you may need a chin strap to keep your mouth closed, or a full face mask to cover your nose and mouth.

The air delivered during therapy may overwhelm the body’s ability to add heat and moisture, which can lead to a sore, dry throat, nasal congestion, or a runny nose. Heated humidification has been shown to help minimize 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 combined the humidifier and the device to make it easier for therapy users to receive these benefits.

The device will work without water in the tub but you’ll need to insert it into the device and turn humidification off in the My Options menu. If you don’t want to use the humidifier, you’ll need to insert a side cover into the device.

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

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

Icons are displayed on the device 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.

The HumidAir™ heated humidifier will rise to a target temperature of 40°C over 20 minutes. The device then holds this temperature for a further 10 minutes, ready for therapy to start. If therapy does not commence in that time, the device 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 device.

EPR™ gently lowers the pressure delivered to you as you exhale – making it easier to breathe out against the air pressure. When EPR is enabled, the delivered pressure will not drop below 4 cm H2O.

This ramp setting is designed to make the beginning of therapy more comfortable. It begins by delivering a low start pressure to help you fall asleep with ease. Then, using its sleep onset detection capability, it comfortably starts ramping up to your prescribed pressure the moment it detects you’ve fallen asleep.

The ramp feature on your device is designed to make the beginning of therapy more comfortable. Ramp time is the period during which the therapy pressure increases from a low start pressure to the prescribed treatment pressure. Ramp time can be set between 5 and 45 minutes, or can be switched off.

If you require oxygen, you will need to use an oxygen port. ResMed recommends using the Oxygen Connector Port, but an Oxygen Side Port Connector may also be used. Note: An Oxygen Diverter Valve can be set up to reduce oxygen build-up in the device if oxygen continues to flow when the therapy device is on standby, or off. If you're using the Standard or SlimLine™ air tubing, we recommend that you place the oxygen port between the device and the air tubing. If you're using the ClimateLineAir™ heated tubing, then the port will need to be fitted between the tubing and the mask.

The material used for the filter is not intended to be cleaned but the filter can be replaced.

The device number (DN) is a 3-digit code that can be found on the label at the back of your device. It provides additional security and is similar to a CVV code on the back of a credit card.

The serial number (SN) and device number (DN) can be found on the label at the back of your device.

Sleep apnea in women is different to sleep apnea in men.1 So it makes sense that their treatment should be different too. ResMed's AirSense™ 10 AutoSet™ for Her device includes a new algorithm that responds to female-specific characteristics of obstructive sleep apnea.

There are a few things to consider before travelling with your therapy device:
• Ensure you remove the humidifier tub and place it in its own compartment in the carry bag.
• When transporting the device, always empty the tub to avoid water damage.
• We recommend that you don't use your humidifier when powering your device with a battery, as the humidifier consumes a great deal of power. Simply go to the My Options menu on your device and turn humidification off.
• If you’re using the AirSense™ 10 AutoSet™ patient trial device on a plane, always enable Airplane Mode and turn humidification off.

The AirSense™ 10 and AirCurve™ 10 devices meet Federal Aviation Administration (FAA) requirements for all phases of air travel, so you can safely take your device on board as carry-on luggage.
When using your device on an airplane:
• Make sure the water tub is completely empty and inserted into your device. Do not use your device with water in the tub during air travel to avoid the risk of water inhalation and spillage during turbulence.
• Ensure humidification is turned off.
• If you’re using the AirSense 10 AutoSet™ patient trial device, ensure Airplane Mode is enabled.
Note: Medical devices do not count towards your carry-on luggage limit.

Yes. Even though the rating plate on the therapy device specifies 50-60Hz, the switch mode power supply in the flow generator is compatible with the 110 volts 400Hz power supply on the aircraft.

While most of our devices will automatically compensate for higher altitude changes, some lightweight devices may require manual adjustment. If no adjustment is made, it may deliver less effective therapy. Please consult your local care provider for more information.

No, the x-ray scanners will not harm your device. However, Security may need to see the medical statement from your physician verifying that you are carrying medical equipment. So keep it handy!

Yes. If you’re having surgery, it’s very important that you tell both the surgeon and the anesthesiologist that you have been diagnosed with obstructive sleep apnea (OSA) and are being treated with positive airway pressure therapy.
