Sleek, Modern Design with Full Color Display: DreamStation's simple shape and full color display are a welcome change for sleep therapy patients used to bulkier, heavier, uglier device options. It is small and light with a modern, non-medical design that looks great on a bedside table, is user friendly, and fits easily in the included travel bag.

Intuitive Graphic User Interface & Ambient Light Sensors: DreamStation's graphic user interface was designed with feedback from patients and doctors so it is easy to use, intelligent and informative. The machine's a large navigation dial is intuitive and convenient; and the bright, front facing display uses simple menus, icons and labels that are easy to understand.

DreamStation's settings can be adjusted while lying down or sitting up in bed and the machine's ambient light sensor adjusts display brightness automatically depending on light levels in the room.

Advanced Auto-CPAP Algorithm Adjusts to Your Changing Needs: The DreamStation Auto is an advanced APAP machine that monitors your breathing for flow limitations and adapts to them, automatically adjusting therapy throughout the night to ensure you're receiving the optimum pressure for a comfortable and successful sleep.

DreamStation Auto goes a step beyond traditional APAP therapy with Opti-Start. When Opti-Start is enabled DreamStation Auto will begin each therapy session at a pressure that is close to the previous session's 90% pressure, in order to reduce the likelihood of residual events at the beginning of a therapy session.

A Step Up, SmartRamp Makes Therapy Easy: In addition to the traditional pressure ramp available on most sleep therapy devices, DreamStation Auto offers SmartRamp for an easier experience at the onset of sleep. When SmartRamp is enabled the DreamStation Auto will monitor your therapy levels, during the ramp period, to deliver lower overall pressure until it detects an obstructive respiratory event. When an event is detected SmartRamp responds to resolve the event, raising pressures as required until the ramp period concludes.

Optional Integrated Humidifier with Heated Tubing: The DreamStation's Heated Humidifier is an elegant match to the DreamStation Auto's intelligent therapy offerings. The humidifier snaps securely onto the back of the DreamStation device to form a single integrated unit that can be setup and adjusted from the machine's primary LCD display.

In "Standard" mode the DreamStation Heated Humidifier acts like a typical heated humidifier, heating to the same pre-selected temperature level throughout the night. But the DreamStation Heated Humidifier can go beyond that with an "Adaptive" mode that delivers a precise, user selected, level of humidification at the mask throughout the night regardless of external factors like room temperature, flow rate, or external humidity. DreamStation Heated Tubing can also be added to provide extra protection from rainout and allow greater humidity levels than traditional non-heated tubing.

Advanced Comfort Features & A-Flex Pressure Relief: Philips Respironics's clinically-proven A-Flex pressure relief technology enhances traditional positive airway pressure therapy to improve comfort and increase compliance. Thanks to the advanced Digital Auto-Trak algorithm, that detects the onset of inspiration and exhalation, the DreamStation Auto delivers just the right amount of pressure relief, at the beginning and end of every breath, to provide a more natural breathing experience.

In addition to A-Flex, DreamStation Auto is equipped with Mask Fit Check tool to help with mask fitting, a Performance Check tool to ensure that your machine is working properly, EZ-Start adaptive therapy technology to help acclimate new sleep therapy users, and Auto On/Off capabilities to automatically start and stop therapy when a user puts on or takes off their mask.

Enhanced Compliance with Bluetooth & the DreamMapper App: The DreamStation Auto was built from the ground up to make therapy tracking and compliance easy and understandable for patients and doctors. Each device comes with Bluetooth built-in and an SD Data Card for data storage. After each sleep session the DreamStation displays a Sleep Progress report on the LCD screen. The Sleep Progress report shows nightly usage over the past 3 sleep sessions as well as summary data from the past 30 days. More detailed information is also available within the "My Info" section of the device or via the free DreamMapper App (iPhone, iPad & Android).

DreamStation Auto tracks, and adjusts therapy levels to respond to, many common OSA related events including Hypopneas, Flow Limitation, Respiratory Effort Related Arousal, Snores, and Leaks. In addition it can detect many symptoms beyond classic OSA -- such as clear airway apneas and periodic breathing -- that may indicate the need for specialized therapy.

FAA Approved & Travel Friendly: The DreamStation Auto is great for home, but it is FAA approved and built for travel as well. Without a humidifier it weighs just 3 lbs and fits easily in the supplied carry case or any overnight travel bag. DC power cord and battery options are also available for camping, air travel and boating.
