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.

The GoodKnight 420E Auto CPAP is capable of recording information about your sleep, such as snoring or apnea events, as well as pressure delivery response. The information can be downloaded with the purchase of the SilverLining Data Management software and cable.
The GoodKnight 420E Auto CPAP can be used with a separate passover or heated humidifier.

Any mask will work with any machine, with one important exception. The ResMed AirMini is only compatible with certain ResMed CPAP masks. Compatible masks for the AirMini are as follows:
When considering another CPAP, APAP or BiPAP machine from ResMed or any other manufacturer, mask compatibility extends to all brands. The AirMini uses non-standard tubing to connect the machine to the mask, and is the primary reason why other masks won't work with the AirMini. Despite this issue, many of our customers consider the AirMini to be an excellent machine.

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. more...
Excellent, silent, light, and the Auto function great
The Machines is very light ,Small size and quiet. GOOD Product
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. more...
This is a very quiet Machine, a feature my wife apprecates more the I do. I also like that it... is small and light and easy to take on a trip. I used a Respironics M Series Auto CPAP with A-Flex before and I prefer the Good Night 420E. more...
I totally love my new APAP! It is so small yet so advanced compared to my old Resmed CPAP. It... took just one night for me to get used to the change. My nose is less bulbous in the morning because its not under pressure all night. At first I was afraid it wasn't working because the pressure increases only when you stop breathing. Overall I think the APAP will put less stress on my mouth which has been affected by the strong CPAP pressure. My teeth began to separate from my tongue pushing against them due to the CPAP air pressure. I also began to develop cavities from "dry mouth". I'm getting the amount of pressure I need and feel refreshed in the morning. more...
The machine is light and performs well. This is my travel APAP. The need for a specific two-part... hose (provided with the machine) was unexpected. This makes it difficult to use this as the back-up to my everyday APAP (if the specific hose fails, the Goodknight is effectively unusable with any other hose). It also makes it impossible to use my existing humidifiers and their short hoses. You can work around it by using the hose supplied with the machine as the input to the humidifier and then a long hose to you headgear. However, this seems to be a waste. As long as the hose does not break -- they all do eventually -- maybe in five years -- this is a very good machine. more...
I am a long time CPAP user and have used the GoodKnight 420G as my travel machine (I do a... lot of traveling). Had an old ResMed S5 unit for home. The 420G wore out after several years and just got a 420G. Took a little getting used to but I could immediately tell I was sleeping better (I was dreaming a lot more, especially in the early morning). The technology in this thing is amazing. The only downside it that it is a bit noisy. And you do have to deal with the extra pressure sensor tube (not a big deal really). The 420G is now my every day machine as I use when not traveling as well. Its been over 5 years since my last sleep study. But with an APAP, I feel no need to go get one now. CPAP.com is great to do business with. I called the help line and actually got a human and then one that was knowledgeable!! more...
This is the second GoodKnight machine that I have owned. The first was not an auto set, but it... was great. The autoset makes for great sleep. more...
Nice auto CPAP for the money, it's quiet, and worked very well with default settings for me. The pressure... sensor that goes up the tube seems to make it have less resistance on exhaling, too. Small package, excellent for travel. more...
