At just 1.5 pounds and half the size of many of it's competitors, the GoodKnight 420E is one of the smallest and lightest CPAP (Continuous Positive Airway Pressure) systems on the market. Add this to the 420E's advanced Auto-Sensing technology, and it's easy to see why this machine is so popular with today's extremely active sleep disorder patients who want to preserve their lifestyles while complying with their prescribed therapy. The GoodKnight 420E model records up to 200 sessions of compliance data with the optional SilverLining® 3 Data Management Software (sold separately), and includes other features of the 420S model.
The auto-CPAP function automatically adapts to airway pressure needs. The new concept of auto-CPAP is based on the Evolution algorithm, in order to deliver the lowest pressure without compromising efficacy. Lower pressure reduces noise, mask leaks and is more comfortable.
The GoodKnight 420E is designed to respond not only to apnea, but also to indicators of increased resistance in the upper airway such as snoring or inspiratory flow limitation. Inspiratory flow limitation is the early phase of a narrowed airway, prior to hypopnea or apnea, and allows a predictive treatment. The analysis of the inspiratory flow contour is used as a noninvasive marker of changes in upper airway resistance to automatically adjust CPAP pressure, and thus prevent an airway collapse. For each apnea, the GoodKnight 420E attempts to classify apneas as obstructive which need pressure increases versus central with the presence of cardiac oscillations where further increases in pressure would be counterproductive. Instead of a constant pressure application, the system provides the minimal pressures necessary to control obstructive events at all times. Thus, if the airway remains stable, the pressure is reduced until the minimum level is reached or a respiratory event is detected.
