The GoodKnight 425ST Bi-Level device offers the same benefits as our GoodKnight 425 Bi-Level device with the added benefit of a backup rate that delivers a machine-triggered breath in the event of apnea or hypopnea. Thanks to a patented turbine-based blower, the GoodKnight 425ST Bi-Level device is whisper-quiet and comfortable for obstructive sleep apnea patients to use. It's also conveniently small and lightweight, making the GoodKnight 425ST Bi-Level device perfect for use at home, on the road or in clinical settings. Sleep laboratories using Puritan Bennett's Sandman sleep diagnostic system will enjoy compatibility and seamless integration with the GoodKnight 425ST Bi-Level device.
