DreamStar Auto is designed to maximize comfort and patient compliance with the therapy. The complete respiratory events detection makes the DreamSta Auto respond to obstructive events, such as inspiratory flow limitation and snoring. The differentiation between obstructive and central events allows the DreamStar Auto to always deliver the optimum pressure, without risking the effectiveness of the applied pressure. The pressure does not rise in the event of apneas or hypopneas known as central. All data are stored in the device memory and available for downloading, either with USB cable or data card, and can be processed and stored in DreamStar Analyze software.
