System One CPAP devices

Continuous Positive Airway Pressure (CPAP) devices deliver a steady, gentle flow of air throughout the night using a prescribed set therapy pressure to open your airway. Devices are equipped with various comfort features such as C-Flex pressure relief technology.

System One bi-level devices

Bi-level therapy devices deliver two levels of pressure during the night – a lower pressure when you breathe out (exhale) and a higher level of pressure when you breathe in (inhale). These devices are sometimes prescribed for people who have trouble tolerating one constant pressure from a CPAP device. Most are equipped with comfort features such as A-Flex pressure relief technology.

System One auto devices

Auto therapy devices sense your needs and provide variable pressures throughout the night. As with the other models, auto therapy devices are equipped with various comfort features such as pressure relief technology.

System One device comfort options

Ramp starting pressure

This gives you the opportunity to fall asleep on a low pressure. You can choose the period of time over which the pressure gradually increases until you reach your prescribed level of pressure.

Pressure relief technology

This enhances traditional pressure therapy and makes it easier to exhale against the pressure delivered through the mask. In some devices, the technology also provides an easier transition from exhalation to inhalation. This feature makes breathing on the device feel more natural, making it easier for you to adapt to therapy and use it for the long-term.


Adding a humidifier to your therapy device may help to improve comfort, especially if you have a dry nose or throat. More sophisticated systems can monitor room temperature and room humidity, and adjust humidification to maintain the selected relative humidity level – even when environmental conditions change. Humidifiers can add heated or cool air to your therapy.
