Puritan Bennett
Compliance with therapy will be easier than ever when sleep apnea patients discover the small, lightweight and quiet GoodKnight® 420 CPAP system. At a mere 1.5 pounds, the GoodKnight 420 device is so small it is barely noticeable at the bedside and convenient to pack for travel. A wide pressure range of 4 to 20 cm H2O and advanced features for patient management make the GoodKnight 420 units equally effective for home or hospital use. Its patient-friendly features include compatibility with the comfortable, nonconfining Breeze SleepGear™ CPAP Interface System.
