GoodKnight 425 Bilevel Machine

This is a bilevel machine which differs from a CPAP in that it switches back and forth between two pressure levels, one higher and one lower, rather than providing one continuous pressure level. The pressure upon inhalation is higher to hold the airway open, but as the user exhales, the pressure drops to a preset lower level. A bilevel machine responds well to people with very high CPAP pressure needs, weak chest wall muscles, lung disease or other health problems that keep them from being able to exhale against a CPAP pressure.

This product is no longer available. A suitable alternative to this device would be the AirCurve 10 VA BiLevel Machine. This auto-adjusting BiPAP automatically chooses the inhale and exhale pressures for you so you don't have to manually set either pressure. It also comes with a built-in heated humidifier for optimal therapy comfort.

BiLevel Travelling Machine

Verified purchase | Apr. 12, 2009 | Verified CPAP.com Customer
I've got a very convenient BiLevel machine at home, but its's quite heavy. So I bought the GoodKnight 425 - This machine is unbeatable for travilling use and I'm very comfortable with that piece.

This is a welcome change from my previous machine which was bulky and noisy. The Goodknight 425 is so quiet you can barely hear the machine when it is on. And it is so light and compact, it is very easy and very convenient to bring it anywhere.

Goodknight 425 Bilevel Machine

Verified purchase | Nov. 04, 2008 | Verified CPAP.com Customer
This unit delivered everything I had hoped it would, and I am very pleased with the results. There is a bit more noise when exhaling than with my bedside unit, but not a problem once you use it for a night or two. Also, the control buttons are a little more difficult to press than I am accustomed to, but not too difficult. I liked the lightness of the unit when travelling, and will consider getting the humidifier as well. The unit appears to be excellent in every other way.

Small but perfectly formed

BiPAP Goodknight 425 Being in the Uk I receive a free BiPAP machine with service and treatment. Unfortunately this means that they are purchased bulk and tend to be the less portable type of machines. I like to travel and having to carry a heavy BiPAP around is a real chore, paticularly because I do not drive and have to use public transport. The second effect of the Health Service monopoly is that very few BiPAPs are purchased privately so they tend to be expensive, double the price than in the USA. To purchase my Goodknight 425 in the UK would have cost me $1700 and a battery pack $700 so I had to import from America. In fact it would be cheaper for me to fly to the USA from England to buy a machine than to buy one here. From confirmed order to arrival was 4 days, exceptionally speedy, and because it was medical equipment it carries no import duty or sales tax. There was a small amount of administration getting a prescription but that was not to difficult. The machine itself is fantastic, light weight, small and easy to use, both US and UK power covered in the one power pack. Combined with the batery pack and all the leads and tools it weighs less than ten pounds, half the previous weight that I was lugging around. I have used it for two nights now to make sure I can get used to it before I travel and it is fine. Excelent in fact, and so quiet. Once I am fully comfortable and familiar with the machine I will try the battery combination to see how long it lasts with my BiPAP settings and how long it takes to charge. If only I can work out some way of charging the battery by solar power then my stays on remote beaches will happen more often and with a lot less worry.

Thanks!
