GoodKnight 420E Auto CPAP Machine

This is an auto-adjusting CPAP machine which is set for a range of pressures, then seeks out and delivers the lowest level of pressure needed to keep the airway open. The pressure level will vary as needed, but it will not lower with each exhalation as a bilevel does. The auto-adjusting CPAPs were designed for patients who are unable to participate in a sleep study or whose pressure needs vary during the night according to their stage of sleep or sleep position. However, any patient will receive very comfortable therapy from this type of CPAP.

This product is no longer available. A suitable replacement for it would be the AirSense 10 AutoSet with Heated Humidifier. The AirSense 10 has a built-in heated humidifier to keep therapy air warm and comfortable during sleep and uses auto-adjusting technology to manage your pressure settings for you.

    Been using it for over 3 weeks. Love it. It is much smaller, much quieter, and seems to perform much better than my previous CPAP system. I'm using the same mask and headgear as before, and it seems to fit more snugly and leak much less.

    I found the GoodKnight 420E machine to be so much better compared to the 420G machine that I've been using. It's because of the auto-pressure and I feel more comfortable and rested after a good night's sleep.
