GoodKnight 425 ST BiLevel System - DISCONTINUED

The GoodKnight 425ST Bi-Level Device offers an amazingly small, compact, and quiet choice in treating obstructive sleep apnea for people who require bi-level positive pressure. As the world’s smallest, lightest bi-level device, the GoodKnight 425ST won’t crowd the nightstand and is easy to pack for travel, making obstructive sleep apnea (OSA) therapy a snap.

The GoodKnight 425ST device provides the added benefit of a backup rate that delivers a machine-triggered breath in the event of apnea or hypopnea.
