The SleepStyle 254 Auto-CPAP detects and effectively responds to flow limitations, apneas and hypopneas to deliver the lowest therapy pressure possible for comfortable, successful sleep therapy. It provides everything you would expect from an advanced Auto-CPAP machine -- 4-20CM Pressure Range, Universal Power Supply, Automatic Leak Compensation, Ramp, and a built in Heated Humidifier -- but it also offers some innovative solutions you may not have expected...

Patients commonly arouse and experience awake states during sleep. During these periods airway pressure is not needed and can actually make it more difficult to get back to sleep. SensAwake uses flow to monitor patients' breathing patterns and promptly lowers pressure during wakeful states to aid the transition back to sleep. The result is more personalized therapy throughout the night -- during both sleep and awake states.

Using a Heated Humidifier during CPAP Therapy is proven to improve therapy acceptance and compliance. The SleepStyle 254's built in heated humidifier offers a truly integrated, compact, and practical solution. The humidifier features Ambient Tracking PLUS Technology that auto-adjusts humidification levels to compensate for changes in room temperature, and humidity loss during mouth/mask leak. In addition users can raise and lower humidity levels with the push of a button whenever desired. Both disposable and long life humidifier chambers are available.

Two kinds of noise can annoy you and your sleeping partner during sleep therapy. There is the noise of the APAP system and the gurgling noise (rainout) that results from condensation forming in the air tube. The SleepStyle 254 addresses both issues. It operates very quietly and, with Ambient Tracking PLUS, it automatically adjusts the level of humidification to minimize rainout noise, from condensation in the system, while maximizing overall comfort levels.

The SleepStyle 254 offers a USB SmartStick and Fisher & Paykels PerformanceMaximizer Software capabilities for easy monitoring of treatment efficacy and comprehensive patient management.

By identifying and automatically compensating for mouth or mask leaks the SleepStyle 254 ensures the patient is effectively treated all night.

With SensAwake the SleepStyle 254 will automatically lower pressure during wakeful states of sleep, but you can also activate the ramp automaticallly. With push button ease users can lower pressure at the start of sleep, or after waking during the night, and the SleepStyle system will raise it slowly over time to create a more comfortable overall sleep experience.
