Innovation + Personalization = Outstanding Results

The SleepStyle™ 200 Auto Series delivers outstanding clinical, patient-care and commercial results due to its innovative SensAwake™ Technology and its unique ability to personalize sleep comfort to the needs of the patient.

Auto-adjusting Pressure

The versatile Auto CPAP device can be used as a titration and long-term treatment solution for your patients. The flow-based auto-adjusting algorithm detects and effectively responds to flow limitations, apneas and hypopneas.

Flow Limitations:

Pressure increases in response to flow limitations up to the maximum set pressure.

Apneas:

Pressure increases in response to apneas, up to a predetermined level, programmable by

the physician.

Hypopneas:

Pressure increases in response to both central and obstructive hypopneas up to the same predetermined level programmed for apneas. Above this level the algorithm will continue to respond to obstructive hypopneas.

SensAwake™

Patients commonly arouse from sleep and experience awake states, during which they are intolerant of the delivered pressure and can have difficulty returning to sleep. To aid the transition back to sleep, patient comfort is critical.

SensAwake™ uses flow to monitor patients’ breathing patterns, senses the critical awake state and promptly reduces the delivered pressure. SensAwake™, together with the advanced auto-adjusting system, personalizes treatment during sleep and awake states. SensAwake™ facilitates the return to sleep to increase sleep quality and ultimately improve therapy uptake.
